We divide 317092 by 15
The aim is to understand the frequency of 15 in 317092.

Moving on to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Step 2:
15 goes into 31 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 30 from 31 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 15

Step 3:
17 divided by 15 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 15 from 17 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 15

On to step 4:
The number 15 fits into 20 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
Deduct 15 from 20 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 15

Step 5:
When dividing 59 by 15, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 2113.0
If we take 45 away from 59, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 15

On to step 6:
When dividing 142 by 15, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 21139.0
If we take 135 away from 142, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 21139.4
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 21139.46
If we subtract 90 from 100, we 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.

On to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 21139.466
Deduct 90 from 100 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.

The quotient of the division is 21139.466, and the remainder is 0.001.
