Let's divide 3924217 by 255
We're looking to find how many times 255 goes into 3924217.

Going ahead to step 1:
255 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 255

Advancing to step 2:
255 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 255

Let's proceed to step 3:
255 can be fit into 392 1 times, resulting in a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 255 from 392 leaves us with 137.
Fetch the next digit (4) from the dividend, attach it to 137 and continue: 1374 / 255

Moving on to step 4:
255 can be fit into 1374 5 times, resulting in a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 1275 from 1374 to get 99.
Bring next digit (2) of the dividend behind the 99 and repeat the process: 992 / 255

Going ahead to step 5:
255 can be fit into 992 3 times, resulting in a remainder of 227.
The next digit of our result is 3. 
Result so far: 153.0
If we take 765 away from 992, we end up with 227.
Bring next digit (1) of the dividend behind the 227 and repeat the process: 2271 / 255

On to step 6:
255 can be fit into 2271 8 times, resulting in a remainder of 231.
Put 8 as the next digit of the answer. 
Result so far: 1538.0
Deduct 2040 from 2271 and we're left with 231.
Bring next digit (7) of the dividend behind the 231 and repeat the process: 2317 / 255

Step 7:
When dividing 2317 by 255, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 15389.0
If we take 2295 away from 2317, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
If we divide 220 by 255, we get 0 and a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 15389.0
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 9:
255 can be fit into 2200 8 times, resulting in a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 15389.08
Subtract 2040 from 2200 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 255 is 6 with a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 15389.086
If we subtract 1530 from 1600, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
255 can be fit into 700 2 times, resulting in a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 15389.0862
Subtract 510 from 700 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
255 can be fit into 1900 7 times, resulting in a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 15389.08627
Subtracting 1785 from 1900 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 13:
1150 divided by 255 is 4 with a remainder of 130.
The next digit of our result is 4. 
Result so far: 15389.086274
Deduct 1020 from 1150 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
When dividing 1300 by 255, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15389.0862745
Subtracting 1275 from 1300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
255 can be fit into 250 0 times, resulting in a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 15389.0862745
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Our division results in 15389.0862745 with a remaining 2.5e-07.
