We're dividing 45681821 by 256 
We're looking to find how many times 256 goes into 45681821.

Let's proceed to step 1:
4 divided by 256 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 256

Step 2:
256 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 256

Advancing to step 3:
256 goes into 456 1 times with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 256 from 456 and we're left with 200.
Include the next digit (8) from the dividend after 200, then repeat: 2008 / 256

Let's proceed to step 4:
256 goes into 2008 7 times with a remainder of 216.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 1792 from 2008 to get 216.
Grab the next digit (1) from the dividend, add it to 216, then carry on: 2161 / 256

Advancing to step 5:
256 goes into 2161 8 times with a remainder of 113.
Put 8 as the next digit of the answer. 
Result so far: 178.0
If we take 2048 away from 2161, we end up with 113.
Bring next digit (8) of the dividend behind the 113 and repeat the process: 1138 / 256

Advancing to step 6:
If we divide 1138 by 256, we get 4 and a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 1784.0
If we subtract 1024 from 1138, we get 114.
Append the next digit (2) from the dividend to 114 and continue with: 1142 / 256

Let's proceed to step 7:
If we divide 1142 by 256, we get 4 and a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 17844.0
Subtracting 1024 from 1142 leaves us with 118.
Take the next digit (1) from the dividend and append it to 118, then repeat: 1181 / 256

Advancing to step 8:
The number 256 fits into 1181 4 times, leaving a remainder of 157.
Use 4 as the next digit of our solution. 
Result so far: 178444.0
Deduct 1024 from 1181 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
256 can be fit into 1570 6 times, resulting in a remainder of 34.
The next digit of our result is 6. 
Result so far: 178444.6
The remainder is 34 after subtracting 1536 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 256 is 1 with a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 178444.61
If we subtract 256 from 340, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
840 divided by 256 is 3 with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 178444.613
If we take 768 away from 840, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
256 can be fit into 720 2 times, resulting in a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 178444.6132
Deduct 512 from 720 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
256 goes into 2080 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 178444.61328
If we subtract 2048 from 2080, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
256 can be fit into 320 1 times, resulting in a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 178444.613281
The remainder is 64 after subtracting 256 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
640 divided by 256 is 2 with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 178444.6132812
Deduct 512 from 640 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.

Going ahead to step 16:
256 goes into 1280 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 178444.61328125
If we take 1280 away from 1280, 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.

After the division, we end up with 178444.61328125 and a remainder of 0.0.
