We look at the division of 818962 by 63 
The aim is to understand the frequency of 63 in 818962.

Going ahead to step 1:
When dividing 8 by 63, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 63

On to step 2:
63 can be fit into 81 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 18 after subtracting 63 from 81.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 63

Moving on to step 3:
188 divided by 63 is 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 126 from 188 and we're left with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 63

Moving on to step 4:
When dividing 629 by 63, we get 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 567 from 629 leaves us with 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 63

Advancing to step 5:
63 goes into 626 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 1299.0
If we subtract 567 from 626, we get 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 63

On to step 6:
When dividing 592 by 63, we get 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 12999.0
If we subtract 567 from 592, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
The number 63 fits into 250 3 times, leaving a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 12999.3
If we take 189 away from 250, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
63 goes into 610 9 times with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 12999.39
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
When dividing 430 by 63, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 12999.396
If we subtract 378 from 430, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
When dividing 520 by 63, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12999.3968
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
160 divided by 63 is 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 12999.39682
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
When dividing 340 by 63, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 12999.396825
If we take 315 away from 340, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
When dividing 250 by 63, we get 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 12999.3968253
Subtract 189 from 250 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
The number 63 fits into 610 9 times, leaving a remainder of 43.
The next digit of our result is 9. 
Result so far: 12999.39682539
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 12999.39682539 and a remainder of 4.3e-08.
