We look at the division of 843905 by 45 
We want to divide 843905 by 45.

On to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 45

Step 2:
The number 45 fits into 84 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 84 leaves us with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 45

Going ahead to step 3:
45 can be fit into 393 8 times, resulting in a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 360 from 393 to get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 45

Step 4:
When dividing 339 by 45, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
Deduct 315 from 339 and we're left with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 45

Going ahead to step 5:
45 can be fit into 240 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1875.0
The remainder is 15 after subtracting 225 from 240.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 45

Going ahead to step 6:
The number 45 fits into 155 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 18753.0
Subtracting 135 from 155 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
45 goes into 200 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 18753.4
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 18753.44
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 18753.44 with a balance of 0.02.
