645562 ÷ 88 
We want to figure out the number of times 645562 can be divided by 88.

Going ahead to step 1:
The number 88 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 88

Moving on to step 2:
88 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 88

Moving on to step 3:
If we divide 645 by 88, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 616 from 645 to get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 88

On to step 4:
If we divide 295 by 88, we get 3 and a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we subtract 264 from 295, we get 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 88

Advancing to step 5:
316 divided by 88 is 3 with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 733.0
If we subtract 264 from 316, we get 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 88

On to step 6:
88 goes into 522 5 times with a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 7335.0
The remainder is 82 after subtracting 440 from 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 7:
If we divide 820 by 88, we get 9 and a remainder of 28.
The next digit of our result is 9. 
Result so far: 7335.9
If we subtract 792 from 820, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
88 can be fit into 280 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 7335.93
Subtracting 264 from 280 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.

Step 9:
When dividing 160 by 88, we get 1 with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 7335.931
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.

Advancing to step 10:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7335.9318
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.

Going ahead to step 11:
If we divide 160 by 88, we get 1 and a remainder of 72.
The next digit of our result is 1. 
Result so far: 7335.93181
Subtract 88 from 160 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.

Let's proceed to step 12:
720 divided by 88 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7335.931818
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.

Let's proceed to step 13:
88 can be fit into 160 1 times, resulting in a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 7335.9318181
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.

Step 14:
88 can be fit into 720 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 7335.93181818
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.

The final outcome is 7335.93181818, with a leftover of 1.6e-08.
