796438 ÷ 15 
The aim is to understand the frequency of 15 in 796438.

On to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 15

Let's proceed to step 2:
The number 15 fits into 79 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 75 from 79 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 15

Advancing to step 3:
When dividing 46 by 15, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 1 after subtracting 45 from 46.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 15

Moving on to step 4:
When dividing 14 by 15, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 15

Going ahead to step 5:
If we divide 143 by 15, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 5309.0
If we take 135 away from 143, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 15

Let's proceed to step 6:
88 divided by 15 is 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 53095.0
Deduct 75 from 88 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 15 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 53095.8
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 53095.86
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 53095.866
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 53095.866, and the remainder is 0.001.
