We look at the division of 159040 by 7 
We want to divide 159040 by 7.

Step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 7

Advancing to step 2:
If we divide 15 by 7, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 14 from 15, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 7

Step 3:
7 goes into 19 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 14 from 19 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 7

Moving on to step 4:
7 goes into 50 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 227.0
If we subtract 49 from 50, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 7

On to step 5:
If we divide 14 by 7, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2272.0
The remainder is 0 after subtracting 14 from 14.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 7

Going ahead to step 6:
When dividing 0 by 7, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22720.0
Deduct 0 from 0 and we're left 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.

On to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 22720.0
Subtracting 0 from 0 leaves us 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.

Advancing to step 8:
0 divided by 7 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22720.0
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 22720.0 with a balance of 0.0.
