We look at the division of 89899444 by 399 
Let's see how many times 399 fits into 89899444.

Going ahead to step 1:
When dividing 8 by 399, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 399

Step 2:
399 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 399

Advancing to step 3:
The number 399 fits into 898 2 times, leaving a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 100 after subtracting 798 from 898.
Append the next digit (9) from the dividend to 100 and continue with: 1009 / 399

Going ahead to step 4:
When dividing 1009 by 399, we get 2 with a remainder of 211.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 211 after subtracting 798 from 1009.
Include the next digit (9) from the dividend after 211, then repeat: 2119 / 399

Advancing to step 5:
The number 399 fits into 2119 5 times, leaving a remainder of 124.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Subtract 1995 from 2119 to get 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 399

Let's proceed to step 6:
If we divide 1244 by 399, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 2253.0
The remainder is 47 after subtracting 1197 from 1244.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 399

Going ahead to step 7:
When dividing 474 by 399, we get 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 22531.0
Subtract 399 from 474 to get 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 399

On to step 8:
399 can be fit into 754 1 times, resulting in a remainder of 355.
Record the quotient 1 as the next digit in the result. 
Result so far: 225311.0
Subtract 399 from 754 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 9:
399 can be fit into 3550 8 times, resulting in a remainder of 358.
Use 8 as the next digit of our solution. 
Result so far: 225311.8
Subtract 3192 from 3550 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 10:
399 can be fit into 3580 8 times, resulting in a remainder of 388.
Put 8 as the next digit of the answer. 
Result so far: 225311.88
Subtracting 3192 from 3580 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 225311.88 and a remainder of 0.388.
