We look at the division of 19866246 by 843 
Let's see how many times 843 fits into 19866246.

Moving on to step 1:
843 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 843

Advancing to step 2:
843 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 843

Advancing to step 3:
The number 843 fits into 198 0 times, leaving a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 198 and we're left with 198.
Grab the next digit (6) from the dividend, add it to 198, then carry on: 1986 / 843

Advancing to step 4:
When dividing 1986 by 843, we get 2 with a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1686 from 1986 to get 300.
Include the next digit (6) from the dividend after 300, then repeat: 3006 / 843

Step 5:
843 can be fit into 3006 3 times, resulting in a remainder of 477.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 2529 away from 3006, we end up with 477.
Fetch the next digit (2) from the dividend, attach it to 477 and continue: 4772 / 843

Step 6:
843 goes into 4772 5 times with a remainder of 557.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
Subtract 4215 from 4772 to get 557.
Fetch the next digit (4) from the dividend, attach it to 557 and continue: 5574 / 843

On to step 7:
843 goes into 5574 6 times with a remainder of 516.
The next digit of our result is 6. 
Result so far: 2356.0
Subtracting 5058 from 5574 leaves us with 516.
Append the next digit (6) from the dividend to 516 and continue with: 5166 / 843

Moving on to step 8:
5166 divided by 843 is 6 with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 23566.0
Subtracting 5058 from 5166 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 9:
1080 divided by 843 is 1 with a remainder of 237.
The next digit of our result is 1. 
Result so far: 23566.1
Subtract 843 from 1080 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 10:
The number 843 fits into 2370 2 times, leaving a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 23566.12
If we subtract 1686 from 2370, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 11:
843 goes into 6840 8 times with a remainder of 96.
The next digit of our result is 8. 
Result so far: 23566.128
Subtracting 6744 from 6840 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
If we divide 960 by 843, we get 1 and a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 23566.1281
Subtracting 843 from 960 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 13:
1170 divided by 843 is 1 with a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 23566.12811
If we take 843 away from 1170, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The final outcome is 23566.12811, with a leftover of 0.000327.
