We're dividing 3952836 by 905 
We want to figure out the number of times 3952836 can be divided by 905.

Going ahead to step 1:
905 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 905

Going ahead to step 2:
The number 905 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 905

Let's proceed to step 3:
905 can be fit into 395 0 times, resulting in a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Grab the next digit (2) from the dividend, add it to 395, then carry on: 3952 / 905

Let's proceed to step 4:
The number 905 fits into 3952 4 times, leaving a remainder of 332.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3620 away from 3952, we end up with 332.
Include the next digit (8) from the dividend after 332, then repeat: 3328 / 905

On to step 5:
If we divide 3328 by 905, we get 3 and a remainder of 613.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 613 after subtracting 2715 from 3328.
Grab the next digit (3) from the dividend, add it to 613, then carry on: 6133 / 905

Moving on to step 6:
The number 905 fits into 6133 6 times, leaving a remainder of 703.
Use 6 as the next digit of our solution. 
Result so far: 436.0
If we take 5430 away from 6133, we end up with 703.
Include the next digit (6) from the dividend after 703, then repeat: 7036 / 905

Step 7:
If we divide 7036 by 905, we get 7 and a remainder of 701.
The next digit of our result is 7. 
Result so far: 4367.0
Subtract 6335 from 7036 to get 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Step 8:
905 can be fit into 7010 7 times, resulting in a remainder of 675.
Put 7 as the next digit of the answer. 
Result so far: 4367.7
The remainder is 675 after subtracting 6335 from 7010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 9:
The number 905 fits into 6750 7 times, leaving a remainder of 415.
Record the quotient 7 as the next digit in the result. 
Result so far: 4367.77
Subtract 6335 from 6750 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

The quotient of the division is 4367.77, and the remainder is 0.415.
