Let's divide 431839 by 4
We want to divide 431839 by 4.

Advancing to step 1:
4 can be fit into 4 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 4 from 4 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Advancing to step 2:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 4

Step 3:
If we divide 31 by 4, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Deduct 28 from 31 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Moving on to step 4:
4 goes into 38 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1079.0
Subtract 36 from 38 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Going ahead to step 5:
23 divided by 4 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 10795.0
If we take 20 away from 23, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Moving on to step 6:
39 divided by 4 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 107959.0
Subtracting 36 from 39 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 107959.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 107959.75
Subtracting 20 from 20 leaves us 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.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 107959.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 107959.75
The remainder is 0 after subtracting 0 from 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 107959.75 with a remaining 0.0.
