We look at the division of 45873 by 80 
Our goal is to divide 45873 by 80.

Step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 80

Going ahead to step 2:
80 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 80

Step 3:
458 divided by 80 is 5 with a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 400 from 458 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 80

Let's proceed to step 4:
The number 80 fits into 587 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 560 from 587 to get 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 80

Step 5:
80 can be fit into 273 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 573.0
If we subtract 240 from 273, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 6:
If we divide 330 by 80, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 573.4
Subtract 320 from 330 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 80, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 573.41
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 573.412
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 573.4125
If we take 400 away from 400, 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.

Let's proceed to step 10:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 573.4125
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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 573.4125
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.

Our division results in 573.4125 with a remaining 0.0.
