We look at the division of 879240 by 43 
Let's see how many times 43 fits into 879240.

Let's proceed to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 43

On to step 2:
43 can be fit into 87 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 86 from 87 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 43

Let's proceed to step 3:
When dividing 19 by 43, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 19, we get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 43

On to step 4:
When dividing 192 by 43, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 204.0
Subtract 172 from 192 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 43

Advancing to step 5:
The number 43 fits into 204 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 2044.0
If we subtract 172 from 204, we get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 43

Step 6:
320 divided by 43 is 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 20447.0
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
43 can be fit into 190 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 20447.4
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
43 can be fit into 180 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20447.44
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 20447.44 and a remainder of 0.008.
