997588 divided by 88 
The aim is to understand the frequency of 88 in 997588.

Step 1:
If we divide 9 by 88, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 88

Let's proceed to step 2:
88 goes into 99 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 11 after subtracting 88 from 99.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 88

Advancing to step 3:
When dividing 117 by 88, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 88 from 117 to get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 88

Moving on to step 4:
88 can be fit into 295 3 times, resulting in a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Deduct 264 from 295 and we're left with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 88

On to step 5:
318 divided by 88 is 3 with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 1133.0
Deduct 264 from 318 and we're left with 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 88

Advancing to step 6:
88 can be fit into 548 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 11336.0
Subtracting 528 from 548 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 88 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 11336.2
If we subtract 176 from 200, we 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.

Advancing to step 8:
88 can be fit into 240 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 11336.22
If we subtract 176 from 240, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 11336.22, and the remainder is 0.064.
