We look at the division of 531450 by 80 
Let's see how many times 80 fits into 531450.

On to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 80

On to step 2:
80 can be fit into 53 0 times, resulting in a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 80

Advancing to step 3:
If we divide 531 by 80, we get 6 and a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 480 from 531 leaves us with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 80

Let's proceed to step 4:
If we divide 514 by 80, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 480 from 514, we get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 80

Advancing to step 5:
The number 80 fits into 345 4 times, leaving a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 664.0
If we subtract 320 from 345, we get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 80

Advancing to step 6:
80 goes into 250 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 6643.0
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
80 can be fit into 100 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 6643.1
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 6643.12
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.

Moving on to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6643.125
Subtracting 400 from 400 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.

Let's proceed to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6643.125
The remainder is 0 after subtracting 0 from 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:
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: 6643.125
If we take 0 away from 0, 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.

In conclusion, the division gives 6643.125 with a balance of 0.0.
