We look at the division of 879166 by 63 
The aim is to understand the frequency of 63 in 879166.

Let's proceed to step 1:
63 goes into 8 0 times 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.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 63

On to step 2:
The number 63 fits into 87 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 63 from 87 to get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 63

Moving on to step 3:
If we divide 249 by 63, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 189 from 249 leaves us with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 63

Going ahead to step 4:
The number 63 fits into 601 9 times, leaving a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 567 from 601 to get 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 63

Step 5:
When dividing 346 by 63, we get 5 with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 1395.0
Subtract 315 from 346 to get 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 63

Let's proceed to step 6:
The number 63 fits into 316 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 13955.0
Deduct 315 from 316 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 63 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13955.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 63, we get 1 and a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 13955.01
The remainder is 37 after subtracting 63 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 63 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 13955.015
If we subtract 315 from 370, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
If we divide 550 by 63, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 13955.0158
Subtracting 504 from 550 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
63 goes into 460 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 13955.01587
Subtract 441 from 460 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
63 goes into 190 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13955.015873
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
The number 63 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13955.015873
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
63 goes into 100 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 13955.01587301
Subtract 63 from 100 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 13955.01587301 with a remaining 3.7e-08.
