512371 ÷ 80 
We're looking to find how many times 80 goes into 512371.

Moving on to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 80

Let's proceed to step 2:
80 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 80

Step 3:
80 can be fit into 512 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 480 from 512, we get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 80

Moving on to step 4:
80 can be fit into 323 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtracting 320 from 323 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 80

Moving on to step 5:
37 divided by 80 is 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 640.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 80

Advancing to step 6:
80 goes into 371 4 times with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 6404.0
Deduct 320 from 371 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
80 can be fit into 510 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 6404.6
Subtract 480 from 510 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 6404.63
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 6404.637
Subtracting 560 from 600 leaves us 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.

On to step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6404.6375
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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6404.6375
Deduct 0 from 0 and we're left 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.

Step 12:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6404.6375
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 6404.6375, and the remainder is 0.0.
