813917 ÷ 88 
The aim is to understand the frequency of 88 in 813917.

On to step 1:
The number 88 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 88

Step 2:
81 divided by 88 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 88

Going ahead to step 3:
88 goes into 813 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 792 from 813 leaves us with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 88

Step 4:
The number 88 fits into 219 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtracting 176 from 219 leaves us with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 88

Step 5:
If we divide 431 by 88, we get 4 and a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 924.0
If we subtract 352 from 431, we get 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 88

Going ahead to step 6:
797 divided by 88 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9249.0
Subtract 792 from 797 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
88 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9249.0
Deduct 0 from 50 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.

Going ahead to step 8:
88 can be fit into 500 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 9249.05
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.

Moving on to step 9:
88 can be fit into 600 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 9249.056
Subtract 528 from 600 to 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.

Step 10:
88 goes into 720 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9249.0568
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.

Moving on to step 11:
88 goes into 160 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 9249.05681
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.

Going ahead to step 12:
88 goes into 720 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9249.056818
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.

Let's proceed to step 13:
If we divide 160 by 88, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 9249.0568181
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.

On to step 14:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 9249.05681818
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 9249.05681818, with a leftover of 1.6e-08.
