662361 ÷ 15 
The aim is to understand the frequency of 15 in 662361.

On to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 15

Going ahead to step 2:
15 goes into 66 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 60 from 66 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 15

Advancing to step 3:
62 divided by 15 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 60 away from 62, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 15

Going ahead to step 4:
15 can be fit into 23 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 441.0
Deduct 15 from 23 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 15

Step 5:
86 divided by 15 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 4415.0
If we take 75 away from 86, we end up with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 15

On to step 6:
The number 15 fits into 111 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 44157.0
If we take 105 away from 111, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 15, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 44157.4
If we subtract 60 from 60, 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.

On to step 8:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44157.4
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.

On to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 44157.4
Deduct 0 from 0 and we're left 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.

The quotient of the division is 44157.4, and the remainder is 0.0.
