We're dividing 3449287 by 924 
Let's see how many times 924 fits into 3449287.

Going ahead to step 1:
924 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 924

Advancing to step 2:
If we divide 34 by 924, we get 0 and a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 924

Step 3:
924 can be fit into 344 0 times, resulting in a remainder of 344.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 344, we end up with 344.
Bring next digit (9) of the dividend behind the 344 and repeat the process: 3449 / 924

On to step 4:
If we divide 3449 by 924, we get 3 and a remainder of 677.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2772 from 3449 leaves us with 677.
Include the next digit (2) from the dividend after 677, then repeat: 6772 / 924

Moving on to step 5:
924 goes into 6772 7 times with a remainder of 304.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 6468 from 6772 to get 304.
Grab the next digit (8) from the dividend, add it to 304, then carry on: 3048 / 924

Going ahead to step 6:
The number 924 fits into 3048 3 times, leaving a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 373.0
If we subtract 2772 from 3048, we get 276.
Include the next digit (7) from the dividend after 276, then repeat: 2767 / 924

Going ahead to step 7:
If we divide 2767 by 924, we get 2 and a remainder of 919.
Put 2 as the next digit of the answer. 
Result so far: 3732.0
If we take 1848 away from 2767, we end up with 919.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9190, and continue the process.

Let's proceed to step 8:
9190 divided by 924 is 9 with a remainder of 874.
The number 9 becomes the next digit in our result. 
Result so far: 3732.9
The remainder is 874 after subtracting 8316 from 9190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

On to step 9:
If we divide 8740 by 924, we get 9 and a remainder of 424.
Put 9 as the next digit of the answer. 
Result so far: 3732.99
Subtracting 8316 from 8740 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Our division results in 3732.99 with a remaining 0.424.
