80970907 ÷ 324 
Our goal is to divide 80970907 by 324.

On to step 1:
If we divide 8 by 324, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 324

Moving on to step 2:
324 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 324

Going ahead to step 3:
324 goes into 809 2 times with a remainder of 161.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 161 after subtracting 648 from 809.
Bring next digit (7) of the dividend behind the 161 and repeat the process: 1617 / 324

Advancing to step 4:
324 goes into 1617 4 times with a remainder of 321.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 321 after subtracting 1296 from 1617.
Append the next digit (0) from the dividend to 321 and continue with: 3210 / 324

Let's proceed to step 5:
When dividing 3210 by 324, we get 9 with a remainder of 294.
Put 9 as the next digit of the answer. 
Result so far: 249.0
If we take 2916 away from 3210, we end up with 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 324

On to step 6:
If we divide 2949 by 324, we get 9 and a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 2499.0
Subtracting 2916 from 2949 leaves us with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 324

Advancing to step 7:
When dividing 330 by 324, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 24991.0
Subtracting 324 from 330 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 324

Step 8:
When dividing 67 by 324, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 249910.0
Subtracting 0 from 67 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
324 can be fit into 670 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 249910.2
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
324 goes into 220 0 times with a remainder of 220.
The next digit of our result is 0. 
Result so far: 249910.2
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
324 goes into 2200 6 times with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 249910.206
Subtract 1944 from 2200 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 12:
324 goes into 2560 7 times with a remainder of 292.
The number 7 becomes the next digit in our result. 
Result so far: 249910.2067
If we take 2268 away from 2560, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 13:
324 goes into 2920 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 249910.20679
If we take 2916 away from 2920, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
If we divide 40 by 324, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 249910.20679
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
If we divide 400 by 324, we get 1 and a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 249910.2067901
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
760 divided by 324 is 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 249910.20679012
Deduct 648 from 760 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 249910.20679012 and a remainder of 1.12e-07.
