99866162 ÷ 339 
We want to divide 99866162 by 339.

Going ahead to step 1:
If we divide 9 by 339, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 339

Let's proceed to step 2:
When dividing 99 by 339, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 339

Step 3:
If we divide 998 by 339, we get 2 and a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 320 after subtracting 678 from 998.
Include the next digit (6) from the dividend after 320, then repeat: 3206 / 339

On to step 4:
When dividing 3206 by 339, we get 9 with a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 3051 from 3206, we get 155.
Append the next digit (6) from the dividend to 155 and continue with: 1556 / 339

Let's proceed to step 5:
1556 divided by 339 is 4 with a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 294.0
If we take 1356 away from 1556, we end up with 200.
Bring next digit (1) of the dividend behind the 200 and repeat the process: 2001 / 339

Advancing to step 6:
When dividing 2001 by 339, we get 5 with a remainder of 306.
Write down 5 as next digit of the result. 
Result so far: 2945.0
If we subtract 1695 from 2001, we get 306.
Fetch the next digit (6) from the dividend, attach it to 306 and continue: 3066 / 339

Let's proceed to step 7:
If we divide 3066 by 339, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 29459.0
If we take 3051 away from 3066, we end up with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 339

Advancing to step 8:
The number 339 fits into 152 0 times, leaving a remainder of 152.
The next digit of our result is 0. 
Result so far: 294590.0
If we take 0 away from 152, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 9:
The number 339 fits into 1520 4 times, leaving a remainder of 164.
The next digit of our result is 4. 
Result so far: 294590.4
Deduct 1356 from 1520 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
1640 divided by 339 is 4 with a remainder of 284.
Put 4 as the next digit of the answer. 
Result so far: 294590.44
The remainder is 284 after subtracting 1356 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final outcome is 294590.44, with a leftover of 0.284.
