We divide 839889 by 4
Our goal is to divide 839889 by 4.

Advancing to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 8 from 8 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Moving on to step 2:
3 divided by 4 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

On to step 3:
When dividing 39 by 4, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Subtract 36 from 39 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 4

On to step 4:
4 goes into 38 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 2099.0
Deduct 36 from 38 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Step 5:
28 divided by 4 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 20997.0
Subtract 28 from 28 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Advancing to step 6:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 209972.0
Subtract 8 from 9 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 goes into 10 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 209972.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 209972.25
Deduct 20 from 20 and we're left 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.

Advancing to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 209972.25
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.

On to step 10:
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: 209972.25
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.

After the division, we end up with 209972.25 and a remainder of 0.0.
