We look at the division of 840873 by 5 
We want to divide 840873 by 5.

Moving on to step 1:
5 goes into 8 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 5 from 8 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 5

Let's proceed to step 2:
If we divide 34 by 5, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 30 from 34, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 5

Step 3:
5 goes into 40 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 168.0
Subtract 40 from 40 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 5

Advancing to step 4:
If we divide 8 by 5, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1681.0
Subtract 5 from 8 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 5

Moving on to step 5:
The number 5 fits into 37 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 16817.0
If we take 35 away from 37, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 5

On to step 6:
5 can be fit into 23 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 168174.0
If we subtract 20 from 23, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 168174.6
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 168174.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 168174.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 168174.6, with a leftover of 0.0.
