We look at the division of 959689 by 63 
The aim is to understand the frequency of 63 in 959689.

On to step 1:
9 divided by 63 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 63

Moving on to step 2:
95 divided by 63 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 63 from 95 and we're left with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 63

Let's proceed to step 3:
If we divide 329 by 63, we get 5 and a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 315 from 329, we get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 63

Going ahead to step 4:
146 divided by 63 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 152.0
Subtract 126 from 146 to get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 63

Step 5:
208 divided by 63 is 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 1523.0
If we take 189 away from 208, we end up with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 63

Moving on to step 6:
The number 63 fits into 199 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 15233.0
The remainder is 10 after subtracting 189 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
63 can be fit into 100 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 15233.1
If we take 63 away from 100, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
The number 63 fits into 370 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 15233.15
If we take 315 away from 370, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
550 divided by 63 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 15233.158
If we subtract 504 from 550, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
When dividing 460 by 63, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 15233.1587
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
63 goes into 190 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 15233.15873
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.

Let's proceed to step 12:
10 divided by 63 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15233.15873
Subtracting 0 from 10 leaves us 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.

Going ahead to step 13:
63 goes into 100 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 15233.1587301
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.

Step 14:
If we divide 370 by 63, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 15233.15873015
The remainder is 55 after subtracting 315 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 15233.15873015 with a remainder of 5.5e-08.
