We look at the division of 878470 by 91 
We're looking to find how many times 91 goes into 878470.

Going ahead to step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 91

Step 2:
91 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 91

Moving on to step 3:
When dividing 878 by 91, we get 9 with a remainder of 59.
The next digit of our result is 9. 
Result so far: 9.0
If we take 819 away from 878, we end up with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 91

Advancing to step 4:
If we divide 594 by 91, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we subtract 546 from 594, we get 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 91

On to step 5:
If we divide 487 by 91, we get 5 and a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 965.0
If we subtract 455 from 487, we get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 91

Going ahead to step 6:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 9653.0
If we subtract 273 from 320, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9653.5
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
91 goes into 150 1 times with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 9653.51
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
If we divide 590 by 91, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 9653.516
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
91 goes into 440 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 9653.5164
If we take 364 away from 440, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
The number 91 fits into 760 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 9653.51648
Deduct 728 from 760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
The number 91 fits into 320 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 9653.516483
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9653.5164835
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
The number 91 fits into 150 1 times, leaving a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 9653.51648351
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The quotient of the division is 9653.51648351, and the remainder is 5.9e-08.
