We're dividing 821636 by 63 
The aim is to understand the frequency of 63 in 821636.

On to step 1:
8 divided by 63 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 63

Going ahead to step 2:
When dividing 82 by 63, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 63 from 82 leaves us with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 63

Going ahead to step 3:
The number 63 fits into 191 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 189 from 191 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 63

On to step 4:
The number 63 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtracting 0 from 26 leaves us with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 63

Advancing to step 5:
63 goes into 263 4 times with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 1304.0
If we subtract 252 from 263, we get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 63

Advancing to step 6:
When dividing 116 by 63, we get 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 13041.0
The remainder is 53 after subtracting 63 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
If we divide 530 by 63, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 13041.8
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 63 fits into 260 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13041.84
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
63 goes into 80 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 13041.841
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
The number 63 fits into 170 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 13041.8412
If we subtract 126 from 170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
The number 63 fits into 440 6 times, leaving a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 13041.84126
If we subtract 378 from 440, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
When dividing 620 by 63, we get 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 13041.841269
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
The number 63 fits into 530 8 times, leaving a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 13041.8412698
Subtract 504 from 530 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
The number 63 fits into 260 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 13041.84126984
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 13041.84126984 with a remaining 8e-09.
