We're dividing 678222 by 90 
Our goal is to divide 678222 by 90.

Advancing to step 1:
When dividing 6 by 90, we get 0 with 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.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 90

Step 2:
The number 90 fits into 67 0 times, leaving a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 90

Going ahead to step 3:
90 goes into 678 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 630 from 678 to get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 90

Let's proceed to step 4:
90 goes into 482 5 times with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 75.0
Deduct 450 from 482 and we're left with 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 90

Advancing to step 5:
When dividing 322 by 90, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 753.0
Subtract 270 from 322 to get 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 90

Going ahead to step 6:
522 divided by 90 is 5 with a remainder of 72.
Record the quotient 5 as the next digit in the result. 
Result so far: 7535.0
If we take 450 away from 522, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
If we divide 720 by 90, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 7535.8
The remainder is 0 after subtracting 720 from 720.
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 8:
0 divided by 90 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7535.8
Subtract 0 from 0 to get 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 9:
0 divided by 90 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7535.8
If we take 0 away from 0, we end up 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 7535.8, and the remainder is 0.0.
