We look at the division of 800173 by 79 
We want to divide 800173 by 79.

Step 1:
If we divide 8 by 79, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 79

Advancing to step 2:
79 can be fit into 80 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 79 from 80, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 79

Going ahead to step 3:
79 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 79

Going ahead to step 4:
79 can be fit into 101 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtract 79 from 101 to get 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 79

Going ahead to step 5:
79 goes into 227 2 times with a remainder of 69.
The next digit of our result is 2. 
Result so far: 1012.0
Subtract 158 from 227 to get 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 79

Let's proceed to step 6:
693 divided by 79 is 8 with a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 10128.0
If we take 632 away from 693, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
The number 79 fits into 610 7 times, leaving a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 10128.7
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
570 divided by 79 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 10128.77
The remainder is 17 after subtracting 553 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 10128.77 and a remainder of 0.017.
