We're dividing 91075313 by 42 
Let's see how many times 42 fits into 91075313.

Going ahead to step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 42

On to step 2:
42 can be fit into 91 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 7 after subtracting 84 from 91.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 42

Advancing to step 3:
If we divide 70 by 42, we get 1 and a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 42 from 70 to get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 42

Advancing to step 4:
If we divide 287 by 42, we get 6 and a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 216.0
Subtract 252 from 287 to get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 42

Let's proceed to step 5:
42 goes into 355 8 times with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 2168.0
If we take 336 away from 355, we end up with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 42

Advancing to step 6:
42 can be fit into 193 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 21684.0
If we take 168 away from 193, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 42

Moving on to step 7:
The number 42 fits into 251 5 times, leaving a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 216845.0
The remainder is 41 after subtracting 210 from 251.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 42

Step 8:
413 divided by 42 is 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 2168459.0
Subtracting 378 from 413 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
42 can be fit into 350 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 2168459.8
The remainder is 14 after subtracting 336 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 42 fits into 140 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 2168459.83
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 42, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 2168459.833
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 2168459.833 with a remainder of 0.0014.
