90518 ÷ 88 
The aim is to understand the frequency of 88 in 90518.

On to step 1:
The number 88 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 88

On to step 2:
The number 88 fits into 90 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 88 from 90 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 88

Let's proceed to step 3:
When dividing 25 by 88, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 88

Advancing to step 4:
When dividing 251 by 88, we get 2 with a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 176 away from 251, we end up with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 88

On to step 5:
If we divide 758 by 88, we get 8 and a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 1028.0
The remainder is 54 after subtracting 704 from 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 6:
88 goes into 540 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1028.6
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
88 can be fit into 120 1 times, resulting in a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1028.61
Subtract 88 from 120 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
If we divide 320 by 88, we get 3 and a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 1028.613
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
88 can be fit into 560 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1028.6136
If we take 528 away from 560, 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.

Advancing to step 10:
88 can be fit into 320 3 times, resulting in a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 1028.61363
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
88 goes into 560 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 1028.613636
Subtracting 528 from 560 leaves us 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.

Step 12:
If we divide 320 by 88, we get 3 and a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 1028.6136363
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
The number 88 fits into 560 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1028.61363636
Subtracting 528 from 560 leaves us 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.

The final outcome is 1028.61363636, with a leftover of 3.2e-08.
