687418 ÷ 88 
The aim is to understand the frequency of 88 in 687418.

Step 1:
6 divided by 88 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 88

Moving on to step 2:
88 can be fit into 68 0 times, resulting in a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 88

On to step 3:
When dividing 687 by 88, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 71 after subtracting 616 from 687.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 88

Let's proceed to step 4:
When dividing 714 by 88, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 704 from 714 leaves us with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 88

Let's proceed to step 5:
88 can be fit into 101 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 781.0
Subtracting 88 from 101 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 88

Advancing to step 6:
138 divided by 88 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 7811.0
Deduct 88 from 138 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
88 can be fit into 500 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 7811.5
Subtracting 440 from 500 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 88 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 7811.56
If we subtract 528 from 600, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7811.568
Deduct 704 from 720 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 88, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 7811.5681
If we take 88 away from 160, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
If we divide 720 by 88, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7811.56818
If we take 704 away from 720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
88 goes into 160 1 times with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 7811.568181
Subtracting 88 from 160 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
When dividing 720 by 88, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7811.5681818
Subtracting 704 from 720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 88, we get 1 and a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 7811.56818181
If we take 88 away from 160, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 7811.56818181 with a remaining 7.2e-08.
