We look at the division of 618555 by 90 
Let's see how many times 90 fits into 618555.

Advancing to step 1:
If we divide 6 by 90, we get 0 and 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.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 90

On to step 2:
90 can be fit into 61 0 times, resulting in a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 90

Let's proceed to step 3:
The number 90 fits into 618 6 times, leaving a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 540 from 618 leaves us with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 90

Step 4:
When dividing 785 by 90, we get 8 with a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 720 away from 785, we end up with 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 90

Step 5:
If we divide 655 by 90, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 687.0
Deduct 630 from 655 and we're left with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 90

Going ahead to step 6:
90 can be fit into 255 2 times, resulting in a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 6872.0
The remainder is 75 after subtracting 180 from 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
When dividing 750 by 90, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 6872.8
Subtract 720 from 750 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 6872.83
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 6872.833
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 6872.833 and a remainder of 0.003.
