We're dividing 91266321 by 945 
Let's see how many times 945 fits into 91266321.

Going ahead to step 1:
945 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 945

Step 2:
91 divided by 945 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (2) from the dividend to 91 and continue with: 912 / 945

On to step 3:
The number 945 fits into 912 0 times, leaving a remainder of 912.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 912, we get 912.
Include the next digit (6) from the dividend after 912, then repeat: 9126 / 945

Going ahead to step 4:
945 can be fit into 9126 9 times, resulting in a remainder of 621.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 8505 from 9126 leaves us with 621.
Fetch the next digit (6) from the dividend, attach it to 621 and continue: 6216 / 945

Going ahead to step 5:
When dividing 6216 by 945, we get 6 with a remainder of 546.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 546 after subtracting 5670 from 6216.
Bring next digit (3) of the dividend behind the 546 and repeat the process: 5463 / 945

Advancing to step 6:
5463 divided by 945 is 5 with a remainder of 738.
The number 5 becomes the next digit in our result. 
Result so far: 965.0
The remainder is 738 after subtracting 4725 from 5463.
Grab the next digit (2) from the dividend, add it to 738, then carry on: 7382 / 945

On to step 7:
7382 divided by 945 is 7 with a remainder of 767.
The number 7 becomes the next digit in our result. 
Result so far: 9657.0
Deduct 6615 from 7382 and we're left with 767.
Include the next digit (1) from the dividend after 767, then repeat: 7671 / 945

Moving on to step 8:
945 goes into 7671 8 times with a remainder of 111.
Use 8 as the next digit of our solution. 
Result so far: 96578.0
Subtract 7560 from 7671 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
The number 945 fits into 1110 1 times, leaving a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 96578.1
If we take 945 away from 1110, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
If we divide 1650 by 945, we get 1 and a remainder of 705.
The number 1 becomes the next digit in our result. 
Result so far: 96578.11
Subtract 945 from 1650 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Our division results in 96578.11 with a remaining 0.705.
