856391 ÷ 91 
We want to divide 856391 by 91.

Advancing to step 1:
91 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 91

Moving on to step 2:
The number 91 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 91

Step 3:
If we divide 856 by 91, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 9.0
If we take 819 away from 856, we end up with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 91

Advancing to step 4:
The number 91 fits into 373 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 364 away from 373, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 91

On to step 5:
91 can be fit into 99 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 941.0
If we subtract 91 from 99, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 91

Advancing to step 6:
The number 91 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 9410.0
The remainder is 81 after subtracting 0 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 7:
91 goes into 810 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 9410.8
If we take 728 away from 810, we end up with 82.
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 8:
91 goes into 820 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9410.89
Deduct 819 from 820 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 91 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9410.89
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 91, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 9410.8901
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 9410.8901
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 9410.890109
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 13:
91 goes into 810 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 9410.8901098
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
91 goes into 820 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9410.89010989
Subtracting 819 from 820 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 9410.89010989 with a balance of 1e-09.
