We look at the division of 285174 by 91 
We want to divide 285174 by 91.

Let's proceed to step 1:
2 divided by 91 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 91

Step 2:
28 divided by 91 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 91

Advancing to step 3:
The number 91 fits into 285 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 273 from 285 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 91

Going ahead to step 4:
When dividing 121 by 91, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 91 from 121 and we're left with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 91

Going ahead to step 5:
When dividing 307 by 91, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 313.0
If we take 273 away from 307, we end up with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 91

Advancing to step 6:
344 divided by 91 is 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 3133.0
If we subtract 273 from 344, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
91 can be fit into 710 7 times, resulting in a remainder of 73.
The next digit of our result is 7. 
Result so far: 3133.7
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 8:
When dividing 730 by 91, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3133.78
If we subtract 728 from 730, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
91 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3133.78
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 91, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 3133.7802
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 91 is 1 with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 3133.78021
Deduct 91 from 180 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 12:
890 divided by 91 is 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 3133.780219
Subtract 819 from 890 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
If we divide 710 by 91, we get 7 and a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 3133.7802197
If we take 637 away from 710, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 14:
730 divided by 91 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3133.78021978
If we subtract 728 from 730, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 3133.78021978 with a remainder of 2e-09.
