Let's divide 870236 by 91
Let's see how many times 91 fits into 870236.

Moving on to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 91

Going ahead to step 2:
If we divide 87 by 91, we get 0 and a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 91

Going ahead to step 3:
When dividing 870 by 91, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 819 from 870, we get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 91

Moving on to step 4:
When dividing 512 by 91, we get 5 with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we take 455 away from 512, we end up with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 91

Moving on to step 5:
The number 91 fits into 573 6 times, leaving a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 956.0
Subtract 546 from 573 to get 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 91

Step 6:
The number 91 fits into 276 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 9563.0
Subtracting 273 from 276 leaves us with 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 7:
91 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9563.0
Deduct 0 from 30 and we're left with 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 8:
If we divide 300 by 91, we get 3 and a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 9563.03
Subtract 273 from 300 to 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.

Moving on to step 9:
If we divide 270 by 91, we get 2 and a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 9563.032
Subtracting 182 from 270 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
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: 9563.0329
If we subtract 819 from 880, we get 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 11:
When dividing 610 by 91, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 9563.03296
If we take 546 away from 610, we end up 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.

Let's proceed to step 12:
If we divide 640 by 91, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 9563.032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
30 divided by 91 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9563.032967
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.

Step 14:
91 goes into 300 3 times with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 9563.03296703
Deduct 273 from 300 and we're left 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.

In conclusion, the division gives 9563.03296703 with a balance of 2.7e-08.
