Let's divide 85284591 by 91
We want to divide 85284591 by 91.

On to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 91

Let's proceed to step 2:
When dividing 85 by 91, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 91

Advancing to step 3:
If we divide 852 by 91, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 819 from 852, we get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 91

Moving on to step 4:
338 divided by 91 is 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we subtract 273 from 338, we get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 91

Moving on to step 5:
654 divided by 91 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 937.0
Subtract 637 from 654 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 91

Going ahead to step 6:
175 divided by 91 is 1 with a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 9371.0
Subtract 91 from 175 to get 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 91

On to step 7:
When dividing 849 by 91, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 93719.0
Deduct 819 from 849 and we're left with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 91

Moving on to step 8:
When dividing 301 by 91, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 937193.0
If we subtract 273 from 301, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 91, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 937193.3
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
If we divide 70 by 91, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 937193.3
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
91 goes into 700 7 times with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 937193.307
The remainder is 63 after subtracting 637 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
When dividing 630 by 91, we get 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 937193.3076
If we take 546 away from 630, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 13:
The number 91 fits into 840 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 937193.30769
If we subtract 819 from 840, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
210 divided by 91 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 937193.307692
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 15:
91 can be fit into 280 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 937193.3076923
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 937193.3076923
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 937193.3076923, and the remainder is 7e-08.
