Let's divide 620397 by 91
We want to figure out the number of times 620397 can be divided by 91.

Advancing to step 1:
When dividing 6 by 91, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 91

On to step 2:
91 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 91

Let's proceed to step 3:
91 can be fit into 620 6 times, resulting in a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 546 from 620, we get 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 91

Let's proceed to step 4:
If we divide 743 by 91, we get 8 and a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 728 from 743 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 91

Going ahead to step 5:
The number 91 fits into 159 1 times, leaving a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 681.0
The remainder is 68 after subtracting 91 from 159.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 91

On to step 6:
91 goes into 687 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 6817.0
Subtracting 637 from 687 leaves us 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.

Let's proceed to step 7:
If we divide 500 by 91, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 6817.5
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
The number 91 fits into 450 4 times, leaving a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 6817.54
If we take 364 away from 450, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
91 can be fit into 860 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 6817.549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
If we divide 410 by 91, we get 4 and a remainder of 46.
The next digit of our result is 4. 
Result so far: 6817.5494
If we subtract 364 from 410, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
When dividing 460 by 91, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6817.54945
If we take 455 away from 460, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
91 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6817.54945
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.

Advancing to step 13:
500 divided by 91 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 6817.5494505
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
91 goes into 450 4 times with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 6817.54945054
If we take 364 away from 450, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 6817.54945054 and a remainder of 8.6e-08.
