We look at the division of 899843 by 42 
We want to figure out the number of times 899843 can be divided by 42.

Let's proceed to step 1:
8 divided by 42 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 42

Advancing to step 2:
42 goes into 89 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 84 from 89 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 42

Moving on to step 3:
42 can be fit into 59 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 42 from 59 to get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 42

Advancing to step 4:
When dividing 178 by 42, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we take 168 away from 178, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 42

Let's proceed to step 5:
42 goes into 104 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2142.0
Subtracting 84 from 104 leaves us with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 42

Going ahead to step 6:
The number 42 fits into 203 4 times, leaving a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 21424.0
The remainder is 35 after subtracting 168 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
350 divided by 42 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 21424.8
The remainder is 14 after subtracting 336 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 42, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 21424.83
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
When dividing 140 by 42, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 21424.833
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 21424.833 with a balance of 0.0014.
