18315790 ÷ 323 
We want to divide 18315790 by 323.

Moving on to step 1:
323 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 323

On to step 2:
The number 323 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 323

Advancing to step 3:
323 goes into 183 0 times with a remainder of 183.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 183, we end up with 183.
Append the next digit (1) from the dividend to 183 and continue with: 1831 / 323

Step 4:
323 can be fit into 1831 5 times, resulting in a remainder of 216.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 1615 from 1831 and we're left with 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 323

Advancing to step 5:
The number 323 fits into 2165 6 times, leaving a remainder of 227.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtracting 1938 from 2165 leaves us with 227.
Fetch the next digit (7) from the dividend, attach it to 227 and continue: 2277 / 323

Going ahead to step 6:
323 can be fit into 2277 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 567.0
If we subtract 2261 from 2277, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 323

Moving on to step 7:
If we divide 169 by 323, we get 0 and a remainder of 169.
The next digit of our result is 0. 
Result so far: 5670.0
If we take 0 away from 169, we end up with 169.
Grab the next digit (0) from the dividend, add it to 169, then carry on: 1690 / 323

Going ahead to step 8:
323 goes into 1690 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 56705.0
If we take 1615 away from 1690, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
When dividing 750 by 323, we get 2 with a remainder of 104.
The next digit of our result is 2. 
Result so far: 56705.2
Deduct 646 from 750 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
When dividing 1040 by 323, we get 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 56705.23
If we subtract 969 from 1040, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
323 goes into 710 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 56705.232
The remainder is 64 after subtracting 646 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
If we divide 640 by 323, we get 1 and a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 56705.2321
The remainder is 317 after subtracting 323 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 13:
The number 323 fits into 3170 9 times, leaving a remainder of 263.
The next digit of our result is 9. 
Result so far: 56705.23219
Subtract 2907 from 3170 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 14:
323 can be fit into 2630 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 56705.232198
If we take 2584 away from 2630, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 15:
When dividing 460 by 323, we get 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 56705.2321981
Subtracting 323 from 460 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 16:
1370 divided by 323 is 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 56705.23219814
Subtract 1292 from 1370 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 56705.23219814, with a leftover of 7.8e-08.
