627524 divided by 15 
The aim is to understand the frequency of 15 in 627524.

On to step 1:
15 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 15

Step 2:
15 can be fit into 62 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 60 from 62 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 15

Advancing to step 3:
When dividing 27 by 15, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 15 away from 27, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 15

On to step 4:
15 goes into 125 8 times with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 418.0
Subtracting 120 from 125 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 15

Let's proceed to step 5:
If we divide 52 by 15, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4183.0
The remainder is 7 after subtracting 45 from 52.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 15

Going ahead to step 6:
If we divide 74 by 15, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 41834.0
Deduct 60 from 74 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 41834.9
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 41834.93
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 41834.933
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 41834.933 with a balance of 0.0005.
