We look at the division of 63403520 by 108 
The aim is to understand the frequency of 108 in 63403520.

On to step 1:
6 divided by 108 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 108

Let's proceed to step 2:
When dividing 63 by 108, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 108

Let's proceed to step 3:
108 can be fit into 634 5 times, resulting in a remainder of 94.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 94 after subtracting 540 from 634.
Include the next digit (0) from the dividend after 94, then repeat: 940 / 108

Step 4:
If we divide 940 by 108, we get 8 and a remainder of 76.
The next digit of our result is 8. 
Result so far: 58.0
If we take 864 away from 940, we end up with 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 108

Advancing to step 5:
763 divided by 108 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 587.0
If we take 756 away from 763, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 108

Let's proceed to step 6:
108 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 5870.0
Deduct 0 from 75 and we're left with 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 108

Let's proceed to step 7:
752 divided by 108 is 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 58706.0
Deduct 648 from 752 and we're left with 104.
Grab the next digit (0) from the dividend, add it to 104, then carry on: 1040 / 108

Moving on to step 8:
When dividing 1040 by 108, we get 9 with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 587069.0
If we subtract 972 from 1040, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
If we divide 680 by 108, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 587069.6
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
108 goes into 320 2 times with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 587069.62
If we take 216 away from 320, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
The number 108 fits into 1040 9 times, leaving a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 587069.629
If we take 972 away from 1040, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
108 goes into 680 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 587069.6296
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
108 goes into 320 2 times with a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 587069.62962
If we take 216 away from 320, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 14:
108 can be fit into 1040 9 times, resulting in a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 587069.629629
The remainder is 68 after subtracting 972 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 15:
The number 108 fits into 680 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 587069.6296296
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
108 can be fit into 320 2 times, resulting in a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 587069.62962962
Subtracting 216 from 320 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 587069.62962962 and a remainder of 1.04e-07.
