We look at the division of 320573 by 79 
Let's see how many times 79 fits into 320573.

On to step 1:
79 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 79

Let's proceed to step 2:
When dividing 32 by 79, we get 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 79

Going ahead to step 3:
The number 79 fits into 320 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 316 from 320 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 79

Going ahead to step 4:
79 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 79

Advancing to step 5:
When dividing 457 by 79, we get 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 405.0
If we subtract 395 from 457, we get 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 79

On to step 6:
The number 79 fits into 623 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 4057.0
Deduct 553 from 623 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
79 goes into 700 8 times with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 4057.8
If we subtract 632 from 700, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
If we divide 680 by 79, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 4057.88
Deduct 632 from 680 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 4057.88, with a leftover of 0.048.
