Let's divide 21200504 by 324
Our goal is to divide 21200504 by 324.

Step 1:
324 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 324

Step 2:
When dividing 21 by 324, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 324

Going ahead to step 3:
324 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Grab the next digit (0) from the dividend, add it to 212, then carry on: 2120 / 324

Step 4:
When dividing 2120 by 324, we get 6 with a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 1944 from 2120 and we're left with 176.
Include the next digit (0) from the dividend after 176, then repeat: 1760 / 324

On to step 5:
If we divide 1760 by 324, we get 5 and a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 1620 from 1760 leaves us with 140.
Grab the next digit (5) from the dividend, add it to 140, then carry on: 1405 / 324

Step 6:
The number 324 fits into 1405 4 times, leaving a remainder of 109.
Use 4 as the next digit of our solution. 
Result so far: 654.0
Subtracting 1296 from 1405 leaves us with 109.
Append the next digit (0) from the dividend to 109 and continue with: 1090 / 324

Moving on to step 7:
When dividing 1090 by 324, we get 3 with a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 6543.0
Deduct 972 from 1090 and we're left with 118.
Include the next digit (4) from the dividend after 118, then repeat: 1184 / 324

Going ahead to step 8:
The number 324 fits into 1184 3 times, leaving a remainder of 212.
Record the quotient 3 as the next digit in the result. 
Result so far: 65433.0
Subtracting 972 from 1184 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 9:
The number 324 fits into 2120 6 times, leaving a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 65433.6
The remainder is 176 after subtracting 1944 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 10:
When dividing 1760 by 324, we get 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 65433.65
Subtracting 1620 from 1760 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
If we divide 1400 by 324, we get 4 and a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 65433.654
Subtract 1296 from 1400 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
When dividing 1040 by 324, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 65433.6543
If we subtract 972 from 1040, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
324 goes into 680 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 65433.65432
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
The number 324 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 65433.65432
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
When dividing 3200 by 324, we get 9 with a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 65433.6543209
If we take 2916 away from 3200, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 16:
When dividing 2840 by 324, we get 8 with a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 65433.65432098
The remainder is 248 after subtracting 2592 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 65433.65432098 with a balance of 2.48e-07.
