We're dividing 602880 by 90 
Let's see how many times 90 fits into 602880.

Going ahead to step 1:
90 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 90

Step 2:
The number 90 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 90

On to step 3:
The number 90 fits into 602 6 times, leaving a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 62 after subtracting 540 from 602.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 90

Let's proceed to step 4:
When dividing 628 by 90, we get 6 with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 66.0
The remainder is 88 after subtracting 540 from 628.
Bring next digit (8) of the dividend behind the 88 and repeat the process: 888 / 90

Going ahead to step 5:
The number 90 fits into 888 9 times, leaving a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 669.0
If we take 810 away from 888, we end up with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 90

Let's proceed to step 6:
The number 90 fits into 780 8 times, leaving a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 6698.0
Deduct 720 from 780 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
90 goes into 600 6 times with a remainder of 60.
The next digit of our result is 6. 
Result so far: 6698.6
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
90 goes into 600 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 6698.66
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 6698.66, and the remainder is 0.06.
