18171855 divided by 318 
We want to divide 18171855 by 318.

Advancing to step 1:
If we divide 1 by 318, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 318

Moving on to step 2:
When dividing 18 by 318, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 318

Moving on to step 3:
181 divided by 318 is 0 with a remainder of 181.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Take the next digit (7) from the dividend and append it to 181, then repeat: 1817 / 318

Going ahead to step 4:
The number 318 fits into 1817 5 times, leaving a remainder of 227.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 1590 from 1817 leaves us with 227.
Grab the next digit (1) from the dividend, add it to 227, then carry on: 2271 / 318

On to step 5:
2271 divided by 318 is 7 with a remainder of 45.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 2226 from 2271, we get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 318

Going ahead to step 6:
318 goes into 458 1 times with a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 571.0
If we subtract 318 from 458, we get 140.
Include the next digit (5) from the dividend after 140, then repeat: 1405 / 318

Advancing to step 7:
318 goes into 1405 4 times with a remainder of 133.
Use 4 as the next digit of our solution. 
Result so far: 5714.0
If we subtract 1272 from 1405, we get 133.
Fetch the next digit (5) from the dividend, attach it to 133 and continue: 1335 / 318

Step 8:
318 goes into 1335 4 times with a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 57144.0
Deduct 1272 from 1335 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
318 goes into 630 1 times with a remainder of 312.
Record the quotient 1 as the next digit in the result. 
Result so far: 57144.1
The remainder is 312 after subtracting 318 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 10:
3120 divided by 318 is 9 with a remainder of 258.
Record the quotient 9 as the next digit in the result. 
Result so far: 57144.19
The remainder is 258 after subtracting 2862 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 11:
If we divide 2580 by 318, we get 8 and a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 57144.198
The remainder is 36 after subtracting 2544 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
318 goes into 360 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 57144.1981
Deduct 318 from 360 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
420 divided by 318 is 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 57144.19811
Subtracting 318 from 420 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 57144.19811 with a remainder of 0.000102.
