Unit Price

The unit price can be calculated by dividing the total price of n items by n:

Elizabeth sold n=12 bows for $12.12, so the unit price is:

$12.12 / 12

=$1.01

The cost of each bow is $1.01

The long division requires us to arrange the number like:

12 | 12.12

The division starts by dividing 12 (of the dividend 12.12) by 12 (the divisor). We get 1. It must be placed atop the dividend::

| 1

12 | 12.12

Now multiply 1x12 and subtract from the dividend:

| 1

12 | 12.12

| -12

|----------

| 0.12

We have found the decimal point. Remove it and add it to the quotient.

| 1.

12 | 12.12

| -12

|----------

| 12

Divide 1 by 12. It's not possible, so we add a 0 to the quotient:

| 1.0

12 | 12.12

| -12

|----------

| 12

Now we divide 12 by 12 again and get 1. This is added to the quotient and subtract 1*12 from the dividend:

| 1.01

12 | 12.12

| -12

|----------

| 12

| -12

| ---------

| 0

The remainder is 0 and the quotient is 1.01
