We look at the division of 99990297 by 306 
We want to divide 99990297 by 306.

Advancing to step 1:
When dividing 9 by 306, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 306

Step 2:
The number 306 fits into 99 0 times, leaving 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.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 306

Let's proceed to step 3:
306 goes into 999 3 times with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 918 away from 999, we end up with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 306

Going ahead to step 4:
The number 306 fits into 819 2 times, leaving a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 612 from 819, we get 207.
Grab the next digit (0) from the dividend, add it to 207, then carry on: 2070 / 306

Step 5:
The number 306 fits into 2070 6 times, leaving a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 326.0
Subtract 1836 from 2070 to get 234.
Append the next digit (2) from the dividend to 234 and continue with: 2342 / 306

Going ahead to step 6:
2342 divided by 306 is 7 with a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 3267.0
Subtract 2142 from 2342 to get 200.
Append the next digit (9) from the dividend to 200 and continue with: 2009 / 306

Going ahead to step 7:
2009 divided by 306 is 6 with a remainder of 173.
The number 6 becomes the next digit in our result. 
Result so far: 32676.0
Subtract 1836 from 2009 to get 173.
Bring next digit (7) of the dividend behind the 173 and repeat the process: 1737 / 306

Step 8:
1737 divided by 306 is 5 with a remainder of 207.
Use 5 as the next digit of our solution. 
Result so far: 326765.0
The remainder is 207 after subtracting 1530 from 1737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 9:
2070 divided by 306 is 6 with a remainder of 234.
Put 6 as the next digit of the answer. 
Result so far: 326765.6
Deduct 1836 from 2070 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 10:
When dividing 2340 by 306, we get 7 with a remainder of 198.
The next digit of our result is 7. 
Result so far: 326765.67
The remainder is 198 after subtracting 2142 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 11:
When dividing 1980 by 306, we get 6 with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 326765.676
Deduct 1836 from 1980 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 12:
306 goes into 1440 4 times with a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 326765.6764
The remainder is 216 after subtracting 1224 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 13:
If we divide 2160 by 306, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 326765.67647
If we subtract 2142 from 2160, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
180 divided by 306 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 326765.67647
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
306 goes into 1800 5 times with a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 326765.6764705
The remainder is 270 after subtracting 1530 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 16:
2700 divided by 306 is 8 with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 326765.67647058
Subtracting 2448 from 2700 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Our division results in 326765.67647058 with a remaining 2.52e-07.
