Let's divide 672458 by 78
We want to divide 672458 by 78.

Advancing to step 1:
78 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 78

On to step 2:
When dividing 67 by 78, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 78

Step 3:
If we divide 672 by 78, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 48 after subtracting 624 from 672.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 78

Moving on to step 4:
78 can be fit into 484 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 468 from 484, we get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 78

Let's proceed to step 5:
The number 78 fits into 165 2 times, leaving a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 862.0
Deduct 156 from 165 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 78

Advancing to step 6:
78 goes into 98 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 8621.0
Subtract 78 from 98 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 78, we get 2 and a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 8621.2
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
78 goes into 440 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8621.25
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 8621.256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8621.2564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 78, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 8621.25641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
78 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8621.25641
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 8621.2564102
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
78 can be fit into 440 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 8621.25641025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 8621.25641025, and the remainder is 5e-08.
