We look at the division of 291733 by 88 
The aim is to understand the frequency of 88 in 291733.

On to step 1:
If we divide 2 by 88, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 88

Moving on to step 2:
The number 88 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 88

On to step 3:
88 can be fit into 291 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 264 from 291 and we're left with 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 88

Step 4:
88 goes into 277 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 13 after subtracting 264 from 277.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 88

Moving on to step 5:
133 divided by 88 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 331.0
If we subtract 88 from 133, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 88

Moving on to step 6:
88 can be fit into 453 5 times, resulting in a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 3315.0
If we subtract 440 from 453, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 88, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 3315.1
Deduct 88 from 130 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
If we divide 420 by 88, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 3315.14
If we take 352 away from 420, 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 9:
If we divide 680 by 88, we get 7 and a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 3315.147
If we subtract 616 from 680, 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.

Moving on to step 10:
If we divide 640 by 88, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 3315.1477
Subtract 616 from 640 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.

After the division, we end up with 3315.1477 and a remainder of 0.00024.
