We're dividing 31437452 by 324 
We want to divide 31437452 by 324.

Step 1:
If we divide 3 by 324, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 324

Step 2:
When dividing 31 by 324, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 324

Let's proceed to step 3:
314 divided by 324 is 0 with a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 314 to get 314.
Fetch the next digit (3) from the dividend, attach it to 314 and continue: 3143 / 324

Moving on to step 4:
324 goes into 3143 9 times with a remainder of 227.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 2916 from 3143 and we're left with 227.
Include the next digit (7) from the dividend after 227, then repeat: 2277 / 324

Step 5:
2277 divided by 324 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 2268 from 2277 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 324

On to step 6:
The number 324 fits into 94 0 times, leaving a remainder of 94.
The next digit of our result is 0. 
Result so far: 970.0
If we take 0 away from 94, we end up with 94.
Take the next digit (5) from the dividend and append it to 94, then repeat: 945 / 324

Going ahead to step 7:
324 can be fit into 945 2 times, resulting in a remainder of 297.
Record the quotient 2 as the next digit in the result. 
Result so far: 9702.0
Deduct 648 from 945 and we're left with 297.
Append the next digit (2) from the dividend to 297 and continue with: 2972 / 324

Moving on to step 8:
324 can be fit into 2972 9 times, resulting in a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 97029.0
If we take 2916 away from 2972, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
324 can be fit into 560 1 times, resulting in a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 97029.1
Deduct 324 from 560 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 10:
The number 324 fits into 2360 7 times, leaving a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 97029.17
If we take 2268 away from 2360, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
920 divided by 324 is 2 with a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 97029.172
If we take 648 away from 920, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 12:
When dividing 2720 by 324, we get 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 97029.1728
Deduct 2592 from 2720 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
The number 324 fits into 1280 3 times, leaving a remainder of 308.
Write down 3 as next digit of the result. 
Result so far: 97029.17283
Deduct 972 from 1280 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 14:
If we divide 3080 by 324, we get 9 and a remainder of 164.
Write down 9 as next digit of the result. 
Result so far: 97029.172839
If we subtract 2916 from 3080, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 15:
1640 divided by 324 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 97029.1728395
The remainder is 20 after subtracting 1620 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
324 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 97029.1728395
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 97029.1728395 with a remainder of 2e-07.
