91920978 ÷ 324 
We want to divide 91920978 by 324.

Moving on to step 1:
The number 324 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 324

Step 2:
324 can be fit into 91 0 times, resulting in a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (9) from the dividend, attach it to 91 and continue: 919 / 324

Let's proceed to step 3:
The number 324 fits into 919 2 times, leaving a remainder of 271.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 648 from 919, we get 271.
Include the next digit (2) from the dividend after 271, then repeat: 2712 / 324

Advancing to step 4:
324 goes into 2712 8 times with a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 2592 from 2712 and we're left with 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 324

Step 5:
The number 324 fits into 1200 3 times, leaving a remainder of 228.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
If we subtract 972 from 1200, we get 228.
Fetch the next digit (9) from the dividend, attach it to 228 and continue: 2289 / 324

Going ahead to step 6:
If we divide 2289 by 324, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 2837.0
Deduct 2268 from 2289 and we're left with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 324

Advancing to step 7:
When dividing 217 by 324, we get 0 with a remainder of 217.
Record the quotient 0 as the next digit in the result. 
Result so far: 28370.0
Subtracting 0 from 217 leaves us with 217.
Grab the next digit (8) from the dividend, add it to 217, then carry on: 2178 / 324

On to step 8:
2178 divided by 324 is 6 with a remainder of 234.
The next digit of our result is 6. 
Result so far: 283706.0
If we subtract 1944 from 2178, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 9:
When dividing 2340 by 324, we get 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 283706.7
Subtract 2268 from 2340 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
324 can be fit into 720 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 283706.72
If we subtract 648 from 720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
If we divide 720 by 324, we get 2 and a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 283706.722
Subtracting 648 from 720 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 283706.722 with a remainder of 0.0072.
