Let's divide 840043 by 24
Let's see how many times 24 fits into 840043.

On to step 1:
If we divide 8 by 24, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 24

Let's proceed to step 2:
The number 24 fits into 84 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 12 after subtracting 72 from 84.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 24

Advancing to step 3:
If we divide 120 by 24, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 120 from 120 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 24

Moving on to step 4:
0 divided by 24 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 24

On to step 5:
24 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 3500.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 24

Moving on to step 6:
If we divide 43 by 24, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 35001.0
If we subtract 24 from 43, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 24 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 35001.7
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
24 can be fit into 220 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 35001.79
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 24 fits into 40 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 35001.791
Deduct 24 from 40 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 24 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 35001.7916
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 35001.79166
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 35001.79166 and a remainder of 1.6e-05.
