Let's divide 55399107 by 256
We're looking to find how many times 256 goes into 55399107.

Moving on to step 1:
If we divide 5 by 256, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 256

Advancing to step 2:
When dividing 55 by 256, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 256

Let's proceed to step 3:
The number 256 fits into 553 2 times, leaving a remainder of 41.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 512 from 553, we get 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 256

Going ahead to step 4:
256 can be fit into 419 1 times, resulting in a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 256 from 419, we get 163.
Append the next digit (9) from the dividend to 163 and continue with: 1639 / 256

Moving on to step 5:
If we divide 1639 by 256, we get 6 and a remainder of 103.
The next digit of our result is 6. 
Result so far: 216.0
If we take 1536 away from 1639, we end up with 103.
Fetch the next digit (1) from the dividend, attach it to 103 and continue: 1031 / 256

Advancing to step 6:
If we divide 1031 by 256, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 2164.0
If we subtract 1024 from 1031, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 256

On to step 7:
70 divided by 256 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 21640.0
Subtracting 0 from 70 leaves us with 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 256

Advancing to step 8:
When dividing 707 by 256, we get 2 with a remainder of 195.
Write down 2 as next digit of the result. 
Result so far: 216402.0
If we subtract 512 from 707, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 9:
If we divide 1950 by 256, we get 7 and a remainder of 158.
Record the quotient 7 as the next digit in the result. 
Result so far: 216402.7
The remainder is 158 after subtracting 1792 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
256 can be fit into 1580 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 216402.76
Subtracting 1536 from 1580 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
256 goes into 440 1 times with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 216402.761
Subtracting 256 from 440 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 12:
1840 divided by 256 is 7 with a remainder of 48.
The next digit of our result is 7. 
Result so far: 216402.7617
If we subtract 1792 from 1840, we 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.

Let's proceed to step 13:
If we divide 480 by 256, we get 1 and a remainder of 224.
Put 1 as the next digit of the answer. 
Result so far: 216402.76171
The remainder is 224 after subtracting 256 from 480.
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:
If we divide 2240 by 256, we get 8 and a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 216402.761718
Subtracting 2048 from 2240 leaves us 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.

Moving on to step 15:
When dividing 1920 by 256, we get 7 with a remainder of 128.
Use 7 as the next digit of our solution. 
Result so far: 216402.7617187
If we take 1792 away from 1920, we end up 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.

On to step 16:
1280 divided by 256 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 216402.76171875
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.

The final outcome is 216402.76171875, with a leftover of 0.0.
