We divide 722007 by 15
The aim is to understand the frequency of 15 in 722007.

Going ahead to step 1:
7 divided by 15 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 15

Moving on to step 2:
If we divide 72 by 15, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 72 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 15

Step 3:
15 goes into 122 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 120 away from 122, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 15

Going ahead to step 4:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 481.0
Subtract 15 from 20 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 15

Moving on to step 5:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4813.0
The remainder is 5 after subtracting 45 from 50.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 15

Advancing to step 6:
15 goes into 57 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 48133.0
Subtracting 45 from 57 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 48133.8
If we take 120 away from 120, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48133.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48133.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 48133.8 with a remaining 0.0.
