We look at the division of 45103699 by 256 
Our goal is to divide 45103699 by 256.

Going ahead to step 1:
256 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 256

Let's proceed to step 2:
If we divide 45 by 256, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 256

Step 3:
256 can be fit into 451 1 times, resulting in a remainder of 195.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 256 from 451 to get 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 256

Advancing to step 4:
1950 divided by 256 is 7 with a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 1792 away from 1950, we end up with 158.
Append the next digit (3) from the dividend to 158 and continue with: 1583 / 256

On to step 5:
If we divide 1583 by 256, we get 6 and a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 176.0
Subtract 1536 from 1583 to get 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 256

On to step 6:
476 divided by 256 is 1 with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 1761.0
If we subtract 256 from 476, we get 220.
Include the next digit (9) from the dividend after 220, then repeat: 2209 / 256

On to step 7:
256 goes into 2209 8 times with a remainder of 161.
Use 8 as the next digit of our solution. 
Result so far: 17618.0
Deduct 2048 from 2209 and we're left with 161.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 256

Step 8:
If we divide 1619 by 256, we get 6 and a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 176186.0
If we take 1536 away from 1619, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
If we divide 830 by 256, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 176186.3
The remainder is 62 after subtracting 768 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
When dividing 620 by 256, we get 2 with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 176186.32
If we subtract 512 from 620, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
If we divide 1080 by 256, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 176186.324
Subtract 1024 from 1080 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
If we divide 560 by 256, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 176186.3242
Subtract 512 from 560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
256 goes into 480 1 times with a remainder of 224.
Put 1 as the next digit of the answer. 
Result so far: 176186.32421
If we take 256 away from 480, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 14:
The number 256 fits into 2240 8 times, leaving a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 176186.324218
The remainder is 192 after subtracting 2048 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 15:
When dividing 1920 by 256, we get 7 with a remainder of 128.
The next digit of our result is 7. 
Result so far: 176186.3242187
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.

Advancing to step 16:
256 goes into 1280 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 176186.32421875
Subtract 1280 from 1280 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 176186.32421875 with a remaining 0.0.
