We're dividing 439789 by 4 
We want to divide 439789 by 4.

Advancing to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Going ahead to step 2:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

On to step 3:
If we divide 39 by 4, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 36 from 39, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

On to step 4:
If we divide 37 by 4, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1099.0
Deduct 36 from 37 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

On to step 5:
18 divided by 4 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 10994.0
If we subtract 16 from 18, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

On to step 6:
If we divide 29 by 4, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 109947.0
Subtract 28 from 29 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 109947.2
If we subtract 8 from 10, we 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.

Let's proceed to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 109947.25
The remainder is 0 after subtracting 20 from 20.
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 9:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 109947.25
Subtracting 0 from 0 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.

Going ahead to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 109947.25
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.

The quotient of the division is 109947.25, and the remainder is 0.0.
