512473 ÷ 78 
Let's see how many times 78 fits into 512473.

Going ahead to step 1:
78 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 78

Going ahead to step 2:
51 divided by 78 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 78

Step 3:
The number 78 fits into 512 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 468 from 512 and we're left with 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 78

Going ahead to step 4:
The number 78 fits into 444 5 times, leaving a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 390 away from 444, we end up with 54.
Fetch the next digit (7) from the dividend, attach it to 54 and continue: 547 / 78

Advancing to step 5:
78 goes into 547 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 657.0
If we take 546 away from 547, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 78

Advancing to step 6:
13 divided by 78 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 6570.0
Deduct 0 from 13 and we're left 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:
The number 78 fits into 130 1 times, leaving a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 6570.1
Subtract 78 from 130 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
78 goes into 520 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 6570.16
If we subtract 468 from 520, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
If we divide 520 by 78, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6570.166
If we take 468 away from 520, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 6570.166, with a leftover of 0.0052.
