Let's divide 88570 by 91
We want to divide 88570 by 91.

On to step 1:
91 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 91

Moving on to step 2:
88 divided by 91 is 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 91

Advancing to step 3:
91 can be fit into 885 9 times, resulting in a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 819 from 885 to get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 91

Going ahead to step 4:
91 goes into 667 7 times with a remainder of 30.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 637 from 667 to get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 91

Step 5:
300 divided by 91 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 973.0
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 6:
If we divide 270 by 91, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 973.2
The remainder is 88 after subtracting 182 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 7:
If we divide 880 by 91, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 973.29
Deduct 819 from 880 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
91 goes into 610 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 973.296
Deduct 546 from 610 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
640 divided by 91 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 973.2967
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 91, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 973.2967
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
300 divided by 91 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 973.296703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
When dividing 270 by 91, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 973.2967032
The remainder is 88 after subtracting 182 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 13:
880 divided by 91 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 973.29670329
Deduct 819 from 880 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 973.29670329, with a leftover of 6.1e-08.
