We divide 86570880 by 108
The aim is to understand the frequency of 108 in 86570880.

Step 1:
The number 108 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 108

Advancing to step 2:
The number 108 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 108

On to step 3:
108 can be fit into 865 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 864 from 865 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 108

Step 4:
If we divide 17 by 108, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 108

Step 5:
When dividing 170 by 108, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
Subtracting 108 from 170 leaves us with 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 108

On to step 6:
The number 108 fits into 628 5 times, leaving a remainder of 88.
The number 5 becomes the next digit in our result. 
Result so far: 8015.0
If we subtract 540 from 628, we get 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 108

Let's proceed to step 7:
When dividing 888 by 108, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 80158.0
The remainder is 24 after subtracting 864 from 888.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 108

Moving on to step 8:
108 can be fit into 240 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 801582.0
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
The number 108 fits into 240 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 801582.2
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 108, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 801582.22
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 801582.22 with a remaining 0.024.
