We look at the division of 399400 by 4 
We want to divide 399400 by 4.

Let's proceed to step 1:
If we divide 3 by 4, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

Advancing to step 2:
If we divide 39 by 4, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 36 from 39 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

Going ahead to step 3:
39 divided by 4 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 36 from 39, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 4

Step 4:
34 divided by 4 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 998.0
Subtracting 32 from 34 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 4

Let's proceed to step 5:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9985.0
If we subtract 20 from 20, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Advancing to step 6:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 99850.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 99850.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 99850.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 99850.0, and the remainder is 0.0.
