We divide 99993890 by 830
We're looking to find how many times 830 goes into 99993890.

Advancing to step 1:
830 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 830

Moving on to step 2:
830 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 830

Moving on to step 3:
830 can be fit into 999 1 times, resulting in a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 830 from 999, we get 169.
Fetch the next digit (9) from the dividend, attach it to 169 and continue: 1699 / 830

Going ahead to step 4:
830 goes into 1699 2 times with a remainder of 39.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1660 from 1699 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 830

Advancing to step 5:
The number 830 fits into 393 0 times, leaving a remainder of 393.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 393, we end up with 393.
Fetch the next digit (8) from the dividend, attach it to 393 and continue: 3938 / 830

Let's proceed to step 6:
3938 divided by 830 is 4 with a remainder of 618.
The next digit of our result is 4. 
Result so far: 1204.0
Deduct 3320 from 3938 and we're left with 618.
Grab the next digit (9) from the dividend, add it to 618, then carry on: 6189 / 830

Step 7:
830 goes into 6189 7 times with a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 12047.0
If we take 5810 away from 6189, we end up with 379.
Take the next digit (0) from the dividend and append it to 379, then repeat: 3790 / 830

Let's proceed to step 8:
When dividing 3790 by 830, we get 4 with a remainder of 470.
Record the quotient 4 as the next digit in the result. 
Result so far: 120474.0
Subtracting 3320 from 3790 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 9:
830 goes into 4700 5 times with a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 120474.5
If we subtract 4150 from 4700, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
When dividing 5500 by 830, we get 6 with a remainder of 520.
The next digit of our result is 6. 
Result so far: 120474.56
The remainder is 520 after subtracting 4980 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 11:
5200 divided by 830 is 6 with a remainder of 220.
Write down 6 as next digit of the result. 
Result so far: 120474.566
The remainder is 220 after subtracting 4980 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 120474.566 with a balance of 0.022.
