We look at the division of 620171 by 91 
We're looking to find how many times 91 goes into 620171.

Step 1:
91 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 91

Step 2:
The number 91 fits into 62 0 times, leaving a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 91

Going ahead to step 3:
620 divided by 91 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 546 from 620 and we're left with 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 91

Going ahead to step 4:
91 goes into 741 8 times with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 728 from 741, we get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 91

Step 5:
91 goes into 137 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 681.0
The remainder is 46 after subtracting 91 from 137.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 91

Going ahead to step 6:
The number 91 fits into 461 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 6815.0
Subtracting 455 from 461 leaves us with 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 7:
60 divided by 91 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 6815.0
Subtracting 0 from 60 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.

On to step 8:
When dividing 600 by 91, we get 6 with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 6815.06
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
If we divide 540 by 91, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 6815.065
Deduct 455 from 540 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 6815.0659
Deduct 819 from 850 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
91 can be fit into 310 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 6815.06593
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
370 divided by 91 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 6815.065934
Subtracting 364 from 370 leaves us with 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 13:
When dividing 60 by 91, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 6815.065934
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.

Going ahead to step 14:
When dividing 600 by 91, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 6815.06593406
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 6815.06593406, and the remainder is 5.4e-08.
