18016390 ÷ 557 
Our goal is to divide 18016390 by 557.

Going ahead to step 1:
If we divide 1 by 557, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 557

Step 2:
The number 557 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 557

Advancing to step 3:
The number 557 fits into 180 0 times, leaving a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 180, we end up with 180.
Take the next digit (1) from the dividend and append it to 180, then repeat: 1801 / 557

Advancing to step 4:
If we divide 1801 by 557, we get 3 and a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1671 from 1801, we get 130.
Grab the next digit (6) from the dividend, add it to 130, then carry on: 1306 / 557

On to step 5:
The number 557 fits into 1306 2 times, leaving a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 32.0
The remainder is 192 after subtracting 1114 from 1306.
Fetch the next digit (3) from the dividend, attach it to 192 and continue: 1923 / 557

Advancing to step 6:
If we divide 1923 by 557, we get 3 and a remainder of 252.
The number 3 becomes the next digit in our result. 
Result so far: 323.0
Subtract 1671 from 1923 to get 252.
Fetch the next digit (9) from the dividend, attach it to 252 and continue: 2529 / 557

Advancing to step 7:
2529 divided by 557 is 4 with a remainder of 301.
Write down 4 as next digit of the result. 
Result so far: 3234.0
The remainder is 301 after subtracting 2228 from 2529.
Take the next digit (0) from the dividend and append it to 301, then repeat: 3010 / 557

Advancing to step 8:
The number 557 fits into 3010 5 times, leaving a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 32345.0
Subtract 2785 from 3010 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 9:
557 goes into 2250 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 32345.4
Deduct 2228 from 2250 and we're left 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.

On to step 10:
557 goes into 220 0 times with a remainder of 220.
The next digit of our result is 0. 
Result so far: 32345.4
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.

Advancing to step 11:
557 can be fit into 2200 3 times, resulting in a remainder of 529.
Put 3 as the next digit of the answer. 
Result so far: 32345.403
If we take 1671 away from 2200, we end up with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 12:
The number 557 fits into 5290 9 times, leaving a remainder of 277.
The next digit of our result is 9. 
Result so far: 32345.4039
Subtracting 5013 from 5290 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 13:
If we divide 2770 by 557, we get 4 and a remainder of 542.
Put 4 as the next digit of the answer. 
Result so far: 32345.40394
Subtracting 2228 from 2770 leaves us with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 14:
557 can be fit into 5420 9 times, resulting in a remainder of 407.
Write down 9 as next digit of the result. 
Result so far: 32345.403949
Deduct 5013 from 5420 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Let's proceed to step 15:
When dividing 4070 by 557, we get 7 with a remainder of 171.
The next digit of our result is 7. 
Result so far: 32345.4039497
If we subtract 3899 from 4070, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 16:
557 goes into 1710 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 32345.40394973
If we take 1671 away from 1710, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 32345.40394973, and the remainder is 3.9e-08.
