451761 divided by 80 
Let's see how many times 80 fits into 451761.

On to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 80

Moving on to step 2:
The number 80 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 80

Going ahead to step 3:
451 divided by 80 is 5 with a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 400 from 451 and we're left with 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 80

Moving on to step 4:
517 divided by 80 is 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtracting 480 from 517 leaves us with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 80

On to step 5:
When dividing 376 by 80, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 564.0
Subtract 320 from 376 to get 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 80

Step 6:
561 divided by 80 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 5647.0
Deduct 560 from 561 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 80 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5647.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 5647.01
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 5647.012
If we take 160 away from 200, 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:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5647.0125
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 11:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5647.0125
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 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5647.0125
If we subtract 0 from 0, 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.

After the division, we end up with 5647.0125 and a remainder of 0.0.
