3420183 divided by 256 
We want to divide 3420183 by 256.

Moving on to step 1:
256 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 256

Moving on to step 2:
The number 256 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 256

Let's proceed to step 3:
342 divided by 256 is 1 with a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 256 from 342 to get 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 256

Advancing to step 4:
256 goes into 860 3 times with a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 768 from 860, we get 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 256

Step 5:
If we divide 921 by 256, we get 3 and a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Subtracting 768 from 921 leaves us with 153.
Include the next digit (8) from the dividend after 153, then repeat: 1538 / 256

Moving on to step 6:
1538 divided by 256 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 1336.0
Subtracting 1536 from 1538 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 256

Going ahead to step 7:
The number 256 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 13360.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
230 divided by 256 is 0 with a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 13360.0
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 9:
2300 divided by 256 is 8 with a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 13360.08
If we subtract 2048 from 2300, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
When dividing 2520 by 256, we get 9 with a remainder of 216.
The number 9 becomes the next digit in our result. 
Result so far: 13360.089
Subtracting 2304 from 2520 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 11:
If we divide 2160 by 256, we get 8 and a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 13360.0898
Subtract 2048 from 2160 to 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: 13360.08984
If we take 1024 away from 1120, we end up 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.

Let's proceed to step 13:
256 can be fit into 960 3 times, resulting in a remainder of 192.
Record the quotient 3 as the next digit in the result. 
Result so far: 13360.089843
If we take 768 away from 960, 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.

Advancing to step 14:
If we divide 1920 by 256, we get 7 and a remainder of 128.
The next digit of our result is 7. 
Result so far: 13360.0898437
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 15:
1280 divided by 256 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13360.08984375
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.

Our division results in 13360.08984375 with a remaining 0.0.
