680401 divided by 91 
Our goal is to divide 680401 by 91.

Going ahead to step 1:
91 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 91

Let's proceed to step 2:
91 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 91

On to step 3:
The number 91 fits into 680 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 637 from 680 leaves us with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 91

Moving on to step 4:
The number 91 fits into 434 4 times, leaving a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 364 from 434 to get 70.
Include the next digit (0) from the dividend after 70, then repeat: 700 / 91

Step 5:
When dividing 700 by 91, we get 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 747.0
Subtract 637 from 700 to get 63.
Grab the next digit (1) from the dividend, add it to 63, then carry on: 631 / 91

Advancing to step 6:
91 can be fit into 631 6 times, resulting in a remainder of 85.
Record the quotient 6 as the next digit in the result. 
Result so far: 7476.0
If we subtract 546 from 631, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 7:
When dividing 850 by 91, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 7476.9
The remainder is 31 after subtracting 819 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
If we divide 310 by 91, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 7476.93
If we subtract 273 from 310, we 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 9:
91 goes into 370 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 7476.934
The remainder is 6 after subtracting 364 from 370.
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 10:
91 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 7476.934
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.

Going ahead to step 11:
If we divide 600 by 91, we get 6 and a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 7476.93406
Subtracting 546 from 600 leaves us 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.

Step 12:
The number 91 fits into 540 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 7476.934065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 13:
When dividing 850 by 91, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 7476.9340659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
91 can be fit into 310 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 7476.93406593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 7476.93406593, with a leftover of 3.7e-08.
