721979 divided by 88 
The aim is to understand the frequency of 88 in 721979.

On to step 1:
The number 88 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 88

Step 2:
88 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 88

Step 3:
721 divided by 88 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 704 from 721, we get 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 88

Moving on to step 4:
179 divided by 88 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 176 from 179, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 88

Step 5:
The number 88 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 820.0
Subtracting 0 from 37 leaves us with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 88

Going ahead to step 6:
The number 88 fits into 379 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 8204.0
The remainder is 27 after subtracting 352 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
88 goes into 270 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 8204.3
If we subtract 264 from 270, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
88 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8204.3
The remainder is 60 after subtracting 0 from 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 9:
The number 88 fits into 600 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 8204.306
If we take 528 away from 600, 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.

Going ahead to step 10:
If we divide 720 by 88, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8204.3068
If we subtract 704 from 720, we get 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 11:
88 can be fit into 160 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 8204.30681
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.

Let's proceed to step 12:
88 can be fit into 720 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8204.306818
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.

Let's proceed to step 13:
88 goes into 160 1 times with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 8204.3068181
Deduct 88 from 160 and we're left 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.

Going ahead to step 14:
720 divided by 88 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 8204.30681818
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.

The final outcome is 8204.30681818, with a leftover of 1.6e-08.
