We look at the division of 692659 by 15 
The aim is to understand the frequency of 15 in 692659.

Let's proceed to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 15

On to step 2:
69 divided by 15 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 9 after subtracting 60 from 69.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 15

On to step 3:
If we divide 92 by 15, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtract 90 from 92 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 15

Let's proceed to step 4:
The number 15 fits into 26 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 461.0
The remainder is 11 after subtracting 15 from 26.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 15

Moving on to step 5:
15 can be fit into 115 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 4617.0
Subtract 105 from 115 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 15

Going ahead to step 6:
If we divide 109 by 15, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 46177.0
Deduct 105 from 109 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 15 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 46177.2
Deduct 30 from 40 and we're left 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.

Let's proceed to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 46177.26
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.

Moving on to step 9:
100 divided by 15 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 46177.266
Subtracting 90 from 100 leaves us 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.

The quotient of the division is 46177.266, and the remainder is 0.001.
