43299213 ÷ 324 
Our goal is to divide 43299213 by 324.

Advancing to step 1:
324 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 324

Step 2:
43 divided by 324 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 324

Advancing to step 3:
324 can be fit into 432 1 times, resulting in a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 324 from 432, we get 108.
Fetch the next digit (9) from the dividend, attach it to 108 and continue: 1089 / 324

Going ahead to step 4:
The number 324 fits into 1089 3 times, leaving a remainder of 117.
The next digit of our result is 3. 
Result so far: 13.0
If we take 972 away from 1089, we end up with 117.
Take the next digit (9) from the dividend and append it to 117, then repeat: 1179 / 324

Advancing to step 5:
1179 divided by 324 is 3 with a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Deduct 972 from 1179 and we're left with 207.
Grab the next digit (2) from the dividend, add it to 207, then carry on: 2072 / 324

Going ahead to step 6:
324 can be fit into 2072 6 times, resulting in a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 1336.0
Subtracting 1944 from 2072 leaves us with 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 324

Going ahead to step 7:
324 can be fit into 1281 3 times, resulting in a remainder of 309.
Write down 3 as next digit of the result. 
Result so far: 13363.0
Deduct 972 from 1281 and we're left with 309.
Grab the next digit (3) from the dividend, add it to 309, then carry on: 3093 / 324

Step 8:
324 goes into 3093 9 times with a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 133639.0
If we subtract 2916 from 3093, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 9:
324 can be fit into 1770 5 times, resulting in a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 133639.5
Subtracting 1620 from 1770 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
324 can be fit into 1500 4 times, resulting in a remainder of 204.
The next digit of our result is 4. 
Result so far: 133639.54
Subtract 1296 from 1500 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 11:
If we divide 2040 by 324, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 133639.546
The remainder is 96 after subtracting 1944 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
If we divide 960 by 324, we get 2 and a remainder of 312.
The next digit of our result is 2. 
Result so far: 133639.5462
Subtracting 648 from 960 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 13:
324 can be fit into 3120 9 times, resulting in a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 133639.54629
If we take 2916 away from 3120, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 14:
324 goes into 2040 6 times with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 133639.546296
If we subtract 1944 from 2040, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
324 goes into 960 2 times with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 133639.5462962
If we subtract 648 from 960, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 16:
When dividing 3120 by 324, we get 9 with a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 133639.54629629
If we subtract 2916 from 3120, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

In conclusion, the division gives 133639.54629629 with a balance of 2.04e-07.
