Let's divide 625756 by 15
The aim is to understand the frequency of 15 in 625756.

Going ahead to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 15

Let's proceed to step 2:
15 can be fit into 62 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 60 from 62 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 15

Let's proceed to step 3:
25 divided by 15 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 10 after subtracting 15 from 25.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 15

Moving on to step 4:
If we divide 107 by 15, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 417.0
Deduct 105 from 107 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 15

Advancing to step 5:
25 divided by 15 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 4171.0
Deduct 15 from 25 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 15

Let's proceed to step 6:
The number 15 fits into 106 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 41717.0
The remainder is 1 after subtracting 105 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 15, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 41717.0
If we take 0 away from 10, 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.

On to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 41717.06
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.

Going ahead to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 41717.066
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.

Our division results in 41717.066 with a remaining 0.001.
