We look at the division of 680809 by 63 
The aim is to understand the frequency of 63 in 680809.

Advancing to step 1:
When dividing 6 by 63, we get 0 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.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 63

Advancing to step 2:
63 goes into 68 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 63 from 68 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 63

Advancing to step 3:
The number 63 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 50, we end up with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 63

Advancing to step 4:
If we divide 508 by 63, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 108.0
The remainder is 4 after subtracting 504 from 508.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 63

Moving on to step 5:
When dividing 40 by 63, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1080.0
If we subtract 0 from 40, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 63

Going ahead to step 6:
The number 63 fits into 409 6 times, leaving a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 10806.0
Deduct 378 from 409 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
If we divide 310 by 63, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 10806.4
The remainder is 58 after subtracting 252 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
63 can be fit into 580 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 10806.49
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
130 divided by 63 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10806.492
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 63, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10806.492
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 63 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 10806.49206
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
If we divide 220 by 63, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 10806.492063
Subtracting 189 from 220 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
If we divide 310 by 63, we get 4 and a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 10806.4920634
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
If we divide 580 by 63, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 10806.49206349
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 10806.49206349 and a remainder of 1.3e-08.
