We divide 8638520 by 88
The aim is to understand the frequency of 88 in 8638520.

Going ahead to step 1:
The number 88 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 / 88

Advancing to step 2:
88 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 88

Moving on to step 3:
88 can be fit into 863 9 times, resulting in a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 71 after subtracting 792 from 863.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 88

On to step 4:
88 can be fit into 718 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 704 from 718 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 88

On to step 5:
145 divided by 88 is 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 981.0
Subtracting 88 from 145 leaves us with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 88

Going ahead to step 6:
88 can be fit into 572 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 9816.0
Subtract 528 from 572 to get 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 88

Moving on to step 7:
440 divided by 88 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 98165.0
Subtract 440 from 440 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 88, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 98165.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 88, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 98165.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 98165.0 with a balance of 0.0.
