We divide 635453 by 80
Our goal is to divide 635453 by 80.

Advancing to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 80

Step 2:
63 divided by 80 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 80

On to step 3:
If we divide 635 by 80, we get 7 and a remainder of 75.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 560 from 635 leaves us with 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 80

Step 4:
If we divide 754 by 80, we get 9 and a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 720 from 754 to get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 80

On to step 5:
When dividing 345 by 80, we get 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 794.0
Subtracting 320 from 345 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 80

Going ahead to step 6:
The number 80 fits into 253 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 7943.0
Subtract 240 from 253 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 80 is 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 7943.1
Subtract 80 from 130 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7943.16
Subtracting 480 from 500 leaves us 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.

Let's proceed to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 7943.162
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7943.1625
Subtract 400 from 400 to 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7943.1625
Subtract 0 from 0 to 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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7943.1625
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.

After the division, we end up with 7943.1625 and a remainder of 0.0.
