We divide 21645660 by 324
We want to divide 21645660 by 324.

On to step 1:
324 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 324

Advancing to step 2:
324 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 324

Moving on to step 3:
If we divide 216 by 324, we get 0 and a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Fetch the next digit (4) from the dividend, attach it to 216 and continue: 2164 / 324

Moving on to step 4:
324 can be fit into 2164 6 times, resulting in a remainder of 220.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 220 after subtracting 1944 from 2164.
Append the next digit (5) from the dividend to 220 and continue with: 2205 / 324

Going ahead to step 5:
When dividing 2205 by 324, we get 6 with a remainder of 261.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 1944 from 2205 and we're left with 261.
Include the next digit (6) from the dividend after 261, then repeat: 2616 / 324

Let's proceed to step 6:
When dividing 2616 by 324, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 668.0
If we take 2592 away from 2616, we end up with 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 324

Going ahead to step 7:
324 goes into 246 0 times with a remainder of 246.
Record the quotient 0 as the next digit in the result. 
Result so far: 6680.0
Subtracting 0 from 246 leaves us with 246.
Include the next digit (0) from the dividend after 246, then repeat: 2460 / 324

Going ahead to step 8:
2460 divided by 324 is 7 with a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 66807.0
If we take 2268 away from 2460, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 9:
The number 324 fits into 1920 5 times, leaving a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 66807.5
If we take 1620 away from 1920, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
324 can be fit into 3000 9 times, resulting in a remainder of 84.
The next digit of our result is 9. 
Result so far: 66807.59
If we take 2916 away from 3000, we end up 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.

On to step 11:
The number 324 fits into 840 2 times, leaving a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 66807.592
Subtracting 648 from 840 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 12:
324 goes into 1920 5 times with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 66807.5925
If we subtract 1620 from 1920, 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.

Let's proceed to step 13:
3000 divided by 324 is 9 with a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 66807.59259
If we take 2916 away from 3000, we end up 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.

On to step 14:
When dividing 840 by 324, we get 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 66807.592592
Deduct 648 from 840 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
1920 divided by 324 is 5 with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 66807.5925925
If we take 1620 away from 1920, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
The number 324 fits into 3000 9 times, leaving a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 66807.59259259
If we take 2916 away from 3000, we end up 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.

The quotient of the division is 66807.59259259, and the remainder is 8.4e-08.
