Let's divide 108538 by 63
The aim is to understand the frequency of 63 in 108538.

Step 1:
If we divide 1 by 63, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 63

Going ahead to step 2:
63 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 63

On to step 3:
The number 63 fits into 108 1 times, leaving a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 63 away from 108, we end up with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 63

Advancing to step 4:
63 goes into 455 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 441 from 455, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 63

Let's proceed to step 5:
The number 63 fits into 143 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 172.0
The remainder is 17 after subtracting 126 from 143.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 63

Step 6:
178 divided by 63 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 1722.0
Subtract 126 from 178 to 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 7:
The number 63 fits into 520 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 1722.8
Deduct 504 from 520 and we're left 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 8:
If we divide 160 by 63, we get 2 and a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1722.82
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 63, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1722.825
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.

Let's proceed to step 10:
When dividing 250 by 63, we get 3 with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 1722.8253
The remainder is 61 after subtracting 189 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 11:
63 can be fit into 610 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 1722.82539
Deduct 567 from 610 and we're left 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.

Moving on to step 12:
The number 63 fits into 430 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1722.825396
If we take 378 away from 430, we end up 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 13:
When dividing 520 by 63, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1722.8253968
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.

Let's proceed to step 14:
63 goes into 160 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1722.82539682
Subtracting 126 from 160 leaves us 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.

The final result is 1722.82539682 with a remainder of 3.4e-08.
