91531866 ÷ 363 
We want to divide 91531866 by 363.

Let's proceed to step 1:
363 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.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 363

Going ahead to step 2:
363 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 363

Going ahead to step 3:
915 divided by 363 is 2 with a remainder of 189.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 726 away from 915, we end up with 189.
Take the next digit (3) from the dividend and append it to 189, then repeat: 1893 / 363

Going ahead to step 4:
1893 divided by 363 is 5 with a remainder of 78.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 1815 from 1893 and we're left with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 363

Moving on to step 5:
The number 363 fits into 781 2 times, leaving a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
If we take 726 away from 781, we end up with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 363

Let's proceed to step 6:
If we divide 558 by 363, we get 1 and a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 2521.0
Subtracting 363 from 558 leaves us with 195.
Include the next digit (6) from the dividend after 195, then repeat: 1956 / 363

Moving on to step 7:
When dividing 1956 by 363, we get 5 with a remainder of 141.
Put 5 as the next digit of the answer. 
Result so far: 25215.0
If we subtract 1815 from 1956, we get 141.
Append the next digit (6) from the dividend to 141 and continue with: 1416 / 363

Advancing to step 8:
If we divide 1416 by 363, we get 3 and a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 252153.0
Subtracting 1089 from 1416 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 9:
The number 363 fits into 3270 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 252153.9
If we take 3267 away from 3270, 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.

Moving on to step 10:
363 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 252153.9
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.

Going ahead to step 11:
The number 363 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 252153.9
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 252153.9 with a balance of 0.03.
