Let's divide 91040275 by 391
Let's see how many times 391 fits into 91040275.

On to step 1:
391 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 391

On to step 2:
If we divide 91 by 391, we get 0 and a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (0) of the dividend behind the 91 and repeat the process: 910 / 391

Going ahead to step 3:
910 divided by 391 is 2 with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 782 away from 910, we end up with 128.
Bring next digit (4) of the dividend behind the 128 and repeat the process: 1284 / 391

Moving on to step 4:
When dividing 1284 by 391, we get 3 with a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 1173 from 1284 to get 111.
Include the next digit (0) from the dividend after 111, then repeat: 1110 / 391

Step 5:
If we divide 1110 by 391, we get 2 and a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Deduct 782 from 1110 and we're left with 328.
Fetch the next digit (2) from the dividend, attach it to 328 and continue: 3282 / 391

Advancing to step 6:
3282 divided by 391 is 8 with a remainder of 154.
Record the quotient 8 as the next digit in the result. 
Result so far: 2328.0
If we subtract 3128 from 3282, we get 154.
Fetch the next digit (7) from the dividend, attach it to 154 and continue: 1547 / 391

Let's proceed to step 7:
391 can be fit into 1547 3 times, resulting in a remainder of 374.
Put 3 as the next digit of the answer. 
Result so far: 23283.0
Subtract 1173 from 1547 to get 374.
Append the next digit (5) from the dividend to 374 and continue with: 3745 / 391

Advancing to step 8:
The number 391 fits into 3745 9 times, leaving a remainder of 226.
The next digit of our result is 9. 
Result so far: 232839.0
The remainder is 226 after subtracting 3519 from 3745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 9:
391 goes into 2260 5 times with a remainder of 305.
The next digit of our result is 5. 
Result so far: 232839.5
Deduct 1955 from 2260 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 10:
The number 391 fits into 3050 7 times, leaving a remainder of 313.
Use 7 as the next digit of our solution. 
Result so far: 232839.57
The remainder is 313 after subtracting 2737 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 11:
391 goes into 3130 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 232839.578
Deduct 3128 from 3130 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
The number 391 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 232839.578
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
If we divide 200 by 391, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 232839.578
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 232839.578 with a remaining 0.0002.
