Let's divide 84247790 by 843
Our goal is to divide 84247790 by 843.

Going ahead to step 1:
8 divided by 843 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 843

On to step 2:
84 divided by 843 is 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 843

Step 3:
843 can be fit into 842 0 times, resulting in a remainder of 842.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 842 to get 842.
Bring next digit (4) of the dividend behind the 842 and repeat the process: 8424 / 843

Let's proceed to step 4:
If we divide 8424 by 843, we get 9 and a remainder of 837.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7587 from 8424, we get 837.
Include the next digit (7) from the dividend after 837, then repeat: 8377 / 843

On to step 5:
8377 divided by 843 is 9 with a remainder of 790.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 790 after subtracting 7587 from 8377.
Bring next digit (7) of the dividend behind the 790 and repeat the process: 7907 / 843

Advancing to step 6:
When dividing 7907 by 843, we get 9 with a remainder of 320.
Put 9 as the next digit of the answer. 
Result so far: 999.0
If we subtract 7587 from 7907, we get 320.
Grab the next digit (9) from the dividend, add it to 320, then carry on: 3209 / 843

On to step 7:
When dividing 3209 by 843, we get 3 with a remainder of 680.
The next digit of our result is 3. 
Result so far: 9993.0
Deduct 2529 from 3209 and we're left with 680.
Include the next digit (0) from the dividend after 680, then repeat: 6800 / 843

Let's proceed to step 8:
The number 843 fits into 6800 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 99938.0
Subtracting 6744 from 6800 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
When dividing 560 by 843, we get 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 99938.0
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 10:
843 goes into 5600 6 times with a remainder of 542.
Record the quotient 6 as the next digit in the result. 
Result so far: 99938.06
Deduct 5058 from 5600 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 11:
843 can be fit into 5420 6 times, resulting in a remainder of 362.
The next digit of our result is 6. 
Result so far: 99938.066
Subtracting 5058 from 5420 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final outcome is 99938.066, with a leftover of 0.0362.
