We look at the division of 678067 by 90 
We're looking to find how many times 90 goes into 678067.

Moving on to step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 90

Let's proceed to step 2:
The number 90 fits into 67 0 times, leaving a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 90

On to step 3:
678 divided by 90 is 7 with a remainder of 48.
The next digit of our result is 7. 
Result so far: 7.0
If we take 630 away from 678, we end up with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 90

On to step 4:
The number 90 fits into 480 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtract 450 from 480 to get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 90

Let's proceed to step 5:
90 goes into 306 3 times with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 753.0
If we subtract 270 from 306, we get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 90

Step 6:
367 divided by 90 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 7534.0
The remainder is 7 after subtracting 360 from 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 90, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 7534.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 7534.07
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
700 divided by 90 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 7534.077
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7534.077, with a leftover of 0.007.
