858079 divided by 91 
We want to divide 858079 by 91.

Moving on to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 91

Moving on to step 2:
85 divided by 91 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (8) from the dividend after 85, then repeat: 858 / 91

Let's proceed to step 3:
91 can be fit into 858 9 times, resulting in a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 39 after subtracting 819 from 858.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 91

On to step 4:
390 divided by 91 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we take 364 away from 390, we end up with 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 91

Let's proceed to step 5:
When dividing 267 by 91, we get 2 with a remainder of 85.
Use 2 as the next digit of our solution. 
Result so far: 942.0
If we subtract 182 from 267, we get 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 91

Let's proceed to step 6:
The number 91 fits into 859 9 times, leaving a remainder of 40.
The next digit of our result is 9. 
Result so far: 9429.0
Subtracting 819 from 859 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 91 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 9429.4
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
91 goes into 360 3 times with a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 9429.43
If we subtract 273 from 360, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 9:
If we divide 870 by 91, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 9429.439
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
510 divided by 91 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 9429.4395
Subtracting 455 from 510 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 91, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 9429.43956
If we take 546 away from 550, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 91 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 9429.43956
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
91 goes into 400 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 9429.4395604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
360 divided by 91 is 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 9429.43956043
If we take 273 away from 360, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 9429.43956043 and a remainder of 8.7e-08.
