99309261 divided by 843 
Let's see how many times 843 fits into 99309261.

On to step 1:
If we divide 9 by 843, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 843

Step 2:
The number 843 fits into 99 0 times, leaving a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 843

On to step 3:
993 divided by 843 is 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 843 away from 993, we end up with 150.
Append the next digit (0) from the dividend to 150 and continue with: 1500 / 843

Moving on to step 4:
If we divide 1500 by 843, we get 1 and a remainder of 657.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 843 away from 1500, we end up with 657.
Fetch the next digit (9) from the dividend, attach it to 657 and continue: 6579 / 843

Moving on to step 5:
6579 divided by 843 is 7 with a remainder of 678.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
The remainder is 678 after subtracting 5901 from 6579.
Bring next digit (2) of the dividend behind the 678 and repeat the process: 6782 / 843

Going ahead to step 6:
If we divide 6782 by 843, we get 8 and a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 1178.0
Subtract 6744 from 6782 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 843

Advancing to step 7:
If we divide 386 by 843, we get 0 and a remainder of 386.
The number 0 becomes the next digit in our result. 
Result so far: 11780.0
The remainder is 386 after subtracting 0 from 386.
Fetch the next digit (1) from the dividend, attach it to 386 and continue: 3861 / 843

On to step 8:
3861 divided by 843 is 4 with a remainder of 489.
Use 4 as the next digit of our solution. 
Result so far: 117804.0
The remainder is 489 after subtracting 3372 from 3861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
4890 divided by 843 is 5 with a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 117804.5
Subtract 4215 from 4890 to get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 10:
If we divide 6750 by 843, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 117804.58
Deduct 6744 from 6750 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
The number 843 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 117804.58
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
The number 843 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 117804.58
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 117804.58 and a remainder of 0.006.
