We're dividing 451755 by 80 
Let's see how many times 80 fits into 451755.

Going ahead to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
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:
45 divided by 80 is 0 with 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.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 80

Moving on to step 3:
If we divide 451 by 80, we get 5 and a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 400 from 451 and we're left with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 80

Let's proceed to step 4:
If we divide 517 by 80, we get 6 and a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtracting 480 from 517 leaves us with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 80

Going ahead to step 5:
80 goes into 375 4 times with a remainder of 55.
The next digit of our result is 4. 
Result so far: 564.0
Subtracting 320 from 375 leaves us with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 80

Step 6:
80 goes into 555 6 times with a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 5646.0
If we subtract 480 from 555, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 7:
The number 80 fits into 750 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 5646.9
Deduct 720 from 750 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
80 goes into 300 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 5646.93
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 80 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 5646.937
If we take 560 away from 600, we end up 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.

Step 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5646.9375
If we subtract 400 from 400, we get 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:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5646.9375
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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 5646.9375
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.

The quotient of the division is 5646.9375, and the remainder is 0.0.
