We look at the division of 959863 by 63 
The aim is to understand the frequency of 63 in 959863.

On to step 1:
If we divide 9 by 63, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 63

Going ahead to step 2:
The number 63 fits into 95 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 63 away from 95, we end up with 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 63

Advancing to step 3:
63 can be fit into 329 5 times, resulting in a remainder of 14.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 315 from 329 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 63

Going ahead to step 4:
63 can be fit into 148 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtracting 126 from 148 leaves us with 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 63

Going ahead to step 5:
When dividing 226 by 63, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 1523.0
Subtract 189 from 226 to get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 63

Let's proceed to step 6:
373 divided by 63 is 5 with a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 15235.0
If we subtract 315 from 373, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
580 divided by 63 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 15235.9
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.

Step 8:
The number 63 fits into 130 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 15235.92
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
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: 15235.92
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.

Advancing to step 10:
The number 63 fits into 400 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 15235.9206
If we subtract 378 from 400, we 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 11:
63 goes into 220 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 15235.92063
If we subtract 189 from 220, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
The number 63 fits into 310 4 times, leaving a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 15235.920634
Subtract 252 from 310 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
The number 63 fits into 580 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 15235.9206349
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.

Advancing to step 14:
When dividing 130 by 63, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15235.92063492
If we subtract 126 from 130, we 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.

The quotient of the division is 15235.92063492, and the remainder is 4e-09.
