We divide 330393 by 91
We want to divide 330393 by 91.

On to step 1:
3 divided by 91 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 91

Let's proceed to step 2:
If we divide 33 by 91, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 91

On to step 3:
91 can be fit into 330 3 times, resulting in a remainder of 57.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 273 from 330 and we're left with 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 91

On to step 4:
91 can be fit into 573 6 times, resulting in a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 27 after subtracting 546 from 573.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 91

On to step 5:
91 can be fit into 279 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 363.0
The remainder is 6 after subtracting 273 from 279.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 91

On to step 6:
When dividing 63 by 91, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 3630.0
Subtract 0 from 63 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
If we divide 630 by 91, we get 6 and a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 3630.6
If we subtract 546 from 630, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
91 goes into 840 9 times with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 3630.69
Subtract 819 from 840 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
The number 91 fits into 210 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 3630.692
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
91 goes into 280 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3630.6923
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 3630.6923
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
If we divide 700 by 91, we get 7 and a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 3630.692307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 13:
If we divide 630 by 91, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 3630.6923076
Subtracting 546 from 630 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
91 can be fit into 840 9 times, resulting in a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 3630.69230769
Subtract 819 from 840 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 3630.69230769, with a leftover of 2.1e-08.
