18086470 ÷ 256 
We want to divide 18086470 by 256.

Going ahead to step 1:
When dividing 1 by 256, we get 0 with 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 / 256

Advancing to step 2:
The number 256 fits into 18 0 times, leaving 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.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 256

Advancing to step 3:
The number 256 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Append the next digit (8) from the dividend to 180 and continue with: 1808 / 256

Step 4:
When dividing 1808 by 256, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 1792 away from 1808, we end up with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 256

Step 5:
The number 256 fits into 166 0 times, leaving a remainder of 166.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtract 0 from 166 to get 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 256

Step 6:
256 can be fit into 1664 6 times, resulting in a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
The remainder is 128 after subtracting 1536 from 1664.
Take the next digit (7) from the dividend and append it to 128, then repeat: 1287 / 256

Step 7:
256 can be fit into 1287 5 times, resulting in a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 7065.0
Subtracting 1280 from 1287 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 256

On to step 8:
70 divided by 256 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 70650.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
256 goes into 700 2 times with a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 70650.2
If we subtract 512 from 700, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 10:
If we divide 1880 by 256, we get 7 and a remainder of 88.
The next digit of our result is 7. 
Result so far: 70650.27
Deduct 1792 from 1880 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
880 divided by 256 is 3 with a remainder of 112.
Record the quotient 3 as the next digit in the result. 
Result so far: 70650.273
If we subtract 768 from 880, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
1120 divided by 256 is 4 with a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 70650.2734
Deduct 1024 from 1120 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 13:
When dividing 960 by 256, we get 3 with a remainder of 192.
The number 3 becomes the next digit in our result. 
Result so far: 70650.27343
If we subtract 768 from 960, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
If we divide 1920 by 256, we get 7 and a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 70650.273437
Subtract 1792 from 1920 to 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.

Moving on to step 15:
The number 256 fits into 1280 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 70650.2734375
The remainder is 0 after subtracting 1280 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 16:
The number 256 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 70650.2734375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 70650.2734375, and the remainder is 0.0.
