We look at the division of 641453 by 80 
We want to figure out the number of times 641453 can be divided by 80.

Advancing to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 80

Moving on to step 2:
64 divided by 80 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 80

Let's proceed to step 3:
80 can be fit into 641 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 640 from 641 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 80

Step 4:
When dividing 14 by 80, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 14, we end up with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 80

Moving on to step 5:
80 goes into 145 1 times with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
The remainder is 65 after subtracting 80 from 145.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 80

Moving on to step 6:
80 goes into 653 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 8018.0
If we take 640 away from 653, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed 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: 8018.1
The remainder is 50 after subtracting 80 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 8018.16
If we take 480 away from 500, we end up 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.

Advancing to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 8018.162
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.

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: 8018.1625
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:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8018.1625
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.

On to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8018.1625
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.

The final outcome is 8018.1625, with a leftover of 0.0.
