Let's divide 858781 by 91
Our goal is to divide 858781 by 91.

Moving on 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
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 91

On to step 2:
85 divided by 91 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 91

Let's proceed to step 3:
When dividing 858 by 91, we get 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 819 from 858 and we're left with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 91

Step 4:
When dividing 397 by 91, we get 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 364 from 397 and we're left with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 91

On to step 5:
The number 91 fits into 338 3 times, leaving a remainder of 65.
Put 3 as the next digit of the answer. 
Result so far: 943.0
Subtracting 273 from 338 leaves us with 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 91

Step 6:
When dividing 651 by 91, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 9437.0
Subtract 637 from 651 to 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.

Going ahead to step 7:
140 divided by 91 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 9437.1
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 8:
When dividing 490 by 91, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9437.15
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
If we divide 350 by 91, we get 3 and a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 9437.153
Subtracting 273 from 350 leaves us 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 10:
If we divide 770 by 91, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 9437.1538
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
The number 91 fits into 420 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 9437.15384
Subtract 364 from 420 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 91 fits into 560 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 9437.153846
If we take 546 away from 560, we end up 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 13:
140 divided by 91 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 9437.1538461
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
When dividing 490 by 91, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 9437.15384615
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 9437.15384615 with a remaining 3.5e-08.
