Let's divide 859901 by 91
We want to divide 859901 by 91.

Going ahead to step 1:
91 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the 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

Step 2:
When dividing 85 by 91, we get 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 91

On to step 3:
859 divided by 91 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 819 from 859, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 91

Advancing to step 4:
91 goes into 409 4 times with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 364 from 409, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 91

Advancing to step 5:
450 divided by 91 is 4 with a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 944.0
Subtracting 364 from 450 leaves us with 86.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 91

Step 6:
When dividing 861 by 91, we get 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 9449.0
The remainder is 42 after subtracting 819 from 861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
The number 91 fits into 420 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9449.4
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
The number 91 fits into 560 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 9449.46
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
91 can be fit into 140 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 9449.461
The remainder is 49 after subtracting 91 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
91 can be fit into 490 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9449.4615
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
91 can be fit into 350 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 9449.46153
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
The number 91 fits into 770 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 9449.461538
Subtracting 728 from 770 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
91 goes into 420 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9449.4615384
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
The number 91 fits into 560 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 9449.46153846
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 9449.46153846 with a remaining 1.4e-08.
