Let's divide 645299 by 91
We want to figure out the number of times 645299 can be divided by 91.

Step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 91

Step 2:
If we divide 64 by 91, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 91

On to step 3:
91 can be fit into 645 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 637 from 645, we get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 91

Let's proceed to step 4:
If we divide 82 by 91, we get 0 and a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 82 and we're left with 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 91

Going ahead to step 5:
829 divided by 91 is 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 709.0
Subtracting 819 from 829 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 91

Going ahead to step 6:
91 goes into 109 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 7091.0
If we take 91 away from 109, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
91 goes into 180 1 times with a remainder of 89.
The next digit of our result is 1. 
Result so far: 7091.1
The remainder is 89 after subtracting 91 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 8:
91 can be fit into 890 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7091.19
Deduct 819 from 890 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
If we divide 710 by 91, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 7091.197
Deduct 637 from 710 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
When dividing 730 by 91, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 7091.1978
Subtracting 728 from 730 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
The number 91 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7091.1978
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
91 goes into 200 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 7091.197802
Subtracting 182 from 200 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
If we divide 180 by 91, we get 1 and a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 7091.1978021
Subtracting 91 from 180 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 14:
91 goes into 890 9 times with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7091.19780219
Deduct 819 from 890 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 7091.19780219 with a remaining 7.1e-08.
