We divide 125217 by 63
The aim is to understand the frequency of 63 in 125217.

Advancing to step 1:
The number 63 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 63

Advancing to step 2:
63 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 63

On to step 3:
63 can be fit into 125 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 63 from 125, we get 62.
Take the next digit (2) from the dividend and append it to 62, then repeat: 622 / 63

Advancing to step 4:
622 divided by 63 is 9 with a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 55 after subtracting 567 from 622.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 63

Moving on to step 5:
The number 63 fits into 551 8 times, leaving a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 198.0
The remainder is 47 after subtracting 504 from 551.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 63

On to step 6:
63 goes into 477 7 times with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 1987.0
Subtracting 441 from 477 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
63 can be fit into 360 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1987.5
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
63 goes into 450 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1987.57
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
When dividing 90 by 63, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1987.571
If we subtract 63 from 90, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
When dividing 270 by 63, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 1987.5714
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 63, we get 2 and a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 1987.57142
If we take 126 away from 180, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
63 can be fit into 540 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1987.571428
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
360 divided by 63 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1987.5714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
If we divide 450 by 63, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 1987.57142857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 1987.57142857, with a leftover of 9e-09.
