673218 divided by 78 
We want to divide 673218 by 78.

Advancing to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 78

Let's proceed to step 2:
78 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 78

Advancing to step 3:
The number 78 fits into 673 8 times, leaving a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 624 from 673 leaves us with 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 78

Moving on to step 4:
78 goes into 492 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 468 from 492 and we're left with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 78

Going ahead to step 5:
If we divide 241 by 78, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 863.0
Subtracting 234 from 241 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 78

Going ahead to step 6:
78 can be fit into 78 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 8631.0
The remainder is 0 after subtracting 78 from 78.
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 7:
If we divide 0 by 78, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8631.0
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.

Advancing to step 8:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8631.0
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.

The final outcome is 8631.0, with a leftover of 0.0.
