We divide 398889 by 4
Our goal is to divide 398889 by 4.

Advancing to step 1:
4 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 4

On to step 2:
39 divided by 4 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 3 after subtracting 36 from 39.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 4

Let's proceed to step 3:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 36 from 38 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

Step 4:
If we divide 28 by 4, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 997.0
The remainder is 0 after subtracting 28 from 28.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Step 5:
If we divide 8 by 4, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 9972.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Let's proceed to step 6:
4 goes into 9 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 99722.0
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.
The number 2 becomes the next digit in our result. 
Result so far: 99722.2
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 99722.25
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.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 99722.25
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.

Let's proceed to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 99722.25
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 final outcome is 99722.25, with a leftover of 0.0.
