45117854 ÷ 256 
We want to figure out the number of times 45117854 can be divided by 256.

Let's proceed to step 1:
If we divide 4 by 256, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 256

On to step 2:
256 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 256

Advancing to step 3:
256 can be fit into 451 1 times, resulting in a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 195 after subtracting 256 from 451.
Bring next digit (1) of the dividend behind the 195 and repeat the process: 1951 / 256

Going ahead to step 4:
If we divide 1951 by 256, we get 7 and a remainder of 159.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 159 after subtracting 1792 from 1951.
Include the next digit (7) from the dividend after 159, then repeat: 1597 / 256

Going ahead to step 5:
If we divide 1597 by 256, we get 6 and a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 176.0
Deduct 1536 from 1597 and we're left with 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 256

Going ahead to step 6:
618 divided by 256 is 2 with a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 1762.0
If we take 512 away from 618, we end up with 106.
Grab the next digit (5) from the dividend, add it to 106, then carry on: 1065 / 256

Going ahead to step 7:
When dividing 1065 by 256, we get 4 with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 17624.0
Subtract 1024 from 1065 to get 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 256

Going ahead to step 8:
256 can be fit into 414 1 times, resulting in a remainder of 158.
Record the quotient 1 as the next digit in the result. 
Result so far: 176241.0
If we take 256 away from 414, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 9:
When dividing 1580 by 256, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 176241.6
Subtract 1536 from 1580 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
256 can be fit into 440 1 times, resulting in a remainder of 184.
The number 1 becomes the next digit in our result. 
Result so far: 176241.61
If we subtract 256 from 440, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
The number 256 fits into 1840 7 times, leaving a remainder of 48.
The next digit of our result is 7. 
Result so far: 176241.617
The remainder is 48 after subtracting 1792 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
256 goes into 480 1 times with a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 176241.6171
If we subtract 256 from 480, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 13:
When dividing 2240 by 256, we get 8 with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 176241.61718
If we take 2048 away from 2240, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
1920 divided by 256 is 7 with a remainder of 128.
The next digit of our result is 7. 
Result so far: 176241.617187
Deduct 1792 from 1920 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 15:
1280 divided by 256 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 176241.6171875
Deduct 1280 from 1280 and we're left 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.

Going ahead to step 16:
256 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 176241.6171875
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 176241.6171875 and a remainder of 0.0.
