Let's divide 18405906 by 843
We want to figure out the number of times 18405906 can be divided by 843.

Let's proceed to step 1:
When dividing 1 by 843, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 843

Going ahead to step 2:
If we divide 18 by 843, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 843

Step 3:
184 divided by 843 is 0 with a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Bring next digit (0) of the dividend behind the 184 and repeat the process: 1840 / 843

Moving on to step 4:
843 goes into 1840 2 times with a remainder of 154.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1686 from 1840 leaves us with 154.
Append the next digit (5) from the dividend to 154 and continue with: 1545 / 843

Step 5:
The number 843 fits into 1545 1 times, leaving a remainder of 702.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 843 from 1545 and we're left with 702.
Include the next digit (9) from the dividend after 702, then repeat: 7029 / 843

On to step 6:
When dividing 7029 by 843, we get 8 with a remainder of 285.
Write down 8 as next digit of the result. 
Result so far: 218.0
Subtract 6744 from 7029 to get 285.
Append the next digit (0) from the dividend to 285 and continue with: 2850 / 843

Let's proceed to step 7:
2850 divided by 843 is 3 with a remainder of 321.
Record the quotient 3 as the next digit in the result. 
Result so far: 2183.0
Subtract 2529 from 2850 to get 321.
Append the next digit (6) from the dividend to 321 and continue with: 3216 / 843

Going ahead to step 8:
If we divide 3216 by 843, we get 3 and a remainder of 687.
Write down 3 as next digit of the result. 
Result so far: 21833.0
Subtract 2529 from 3216 to get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

On to step 9:
The number 843 fits into 6870 8 times, leaving a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 21833.8
Subtract 6744 from 6870 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 10:
843 can be fit into 1260 1 times, resulting in a remainder of 417.
The next digit of our result is 1. 
Result so far: 21833.81
If we take 843 away from 1260, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Going ahead to step 11:
843 can be fit into 4170 4 times, resulting in a remainder of 798.
Use 4 as the next digit of our solution. 
Result so far: 21833.814
If we subtract 3372 from 4170, we get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Advancing to step 12:
If we divide 7980 by 843, we get 9 and a remainder of 393.
The next digit of our result is 9. 
Result so far: 21833.8149
Deduct 7587 from 7980 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 13:
3930 divided by 843 is 4 with a remainder of 558.
The number 4 becomes the next digit in our result. 
Result so far: 21833.81494
If we take 3372 away from 3930, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 14:
843 can be fit into 5580 6 times, resulting in a remainder of 522.
Record the quotient 6 as the next digit in the result. 
Result so far: 21833.814946
Subtract 5058 from 5580 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 15:
843 goes into 5220 6 times with a remainder of 162.
Record the quotient 6 as the next digit in the result. 
Result so far: 21833.8149466
If we subtract 5058 from 5220, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final result is 21833.8149466 with a remainder of 1.62e-06.
