We look at the division of 374866 by 63 
The aim is to understand the frequency of 63 in 374866.

Advancing to step 1:
63 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 63

Going ahead to step 2:
37 divided by 63 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 63

On to step 3:
If we divide 374 by 63, we get 5 and a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 315 away from 374, we end up with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 63

On to step 4:
598 divided by 63 is 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtract 567 from 598 to get 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 63

Step 5:
When dividing 316 by 63, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 595.0
If we take 315 away from 316, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 63

Moving on to step 6:
When dividing 16 by 63, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 5950.0
Subtracting 0 from 16 leaves us 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.

Advancing to step 7:
160 divided by 63 is 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 5950.2
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
63 goes into 340 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5950.25
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
63 can be fit into 250 3 times, resulting in a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 5950.253
Subtracting 189 from 250 leaves us 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 10:
610 divided by 63 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 5950.2539
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.

On to step 11:
If we divide 430 by 63, we get 6 and a remainder of 52.
The next digit of our result is 6. 
Result so far: 5950.25396
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
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: 5950.253968
Subtracting 504 from 520 leaves us 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.

Moving on to step 13:
When dividing 160 by 63, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 5950.2539682
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
63 can be fit into 340 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5950.25396825
Subtract 315 from 340 to 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.

Our division results in 5950.25396825 with a remaining 2.5e-08.
