81373070 divided by 324 
We want to figure out the number of times 81373070 can be divided by 324.

Advancing to step 1:
The number 324 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 324

Let's proceed to step 2:
81 divided by 324 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 324

Going ahead to step 3:
If we divide 813 by 324, we get 2 and a remainder of 165.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 648 from 813, we get 165.
Bring next digit (7) of the dividend behind the 165 and repeat the process: 1657 / 324

Moving on to step 4:
324 can be fit into 1657 5 times, resulting in a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 1620 from 1657 leaves us with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 324

Step 5:
373 divided by 324 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 251.0
If we take 324 away from 373, we end up with 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 324

Step 6:
324 goes into 490 1 times with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 2511.0
Subtract 324 from 490 to get 166.
Fetch the next digit (7) from the dividend, attach it to 166 and continue: 1667 / 324

Let's proceed to step 7:
When dividing 1667 by 324, we get 5 with a remainder of 47.
The number 5 becomes the next digit in our result. 
Result so far: 25115.0
The remainder is 47 after subtracting 1620 from 1667.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 324

Moving on to step 8:
When dividing 470 by 324, we get 1 with a remainder of 146.
The number 1 becomes the next digit in our result. 
Result so far: 251151.0
Subtracting 324 from 470 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 9:
The number 324 fits into 1460 4 times, leaving a remainder of 164.
Record the quotient 4 as the next digit in the result. 
Result so far: 251151.4
If we subtract 1296 from 1460, 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.

On to step 10:
324 goes into 1640 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 251151.45
If we subtract 1620 from 1640, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
The number 324 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 251151.45
Deduct 0 from 200 and we're left 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.

Step 12:
When dividing 2000 by 324, we get 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 251151.4506
Subtract 1944 from 2000 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
324 can be fit into 560 1 times, resulting in a remainder of 236.
Put 1 as the next digit of the answer. 
Result so far: 251151.45061
Subtract 324 from 560 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 14:
If we divide 2360 by 324, we get 7 and a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 251151.450617
Subtracting 2268 from 2360 leaves us 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.

Step 15:
324 goes into 920 2 times with a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 251151.4506172
If we subtract 648 from 920, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 16:
The number 324 fits into 2720 8 times, leaving a remainder of 128.
The next digit of our result is 8. 
Result so far: 251151.45061728
If we subtract 2592 from 2720, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 251151.45061728, with a leftover of 1.28e-07.
