Let's divide 606388 by 90
Let's see how many times 90 fits into 606388.

Let's proceed 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
If we take 0 away from 6, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 90

Advancing to step 2:
If we divide 60 by 90, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (6) from the dividend, attach it to 60 and continue: 606 / 90

Moving on to step 3:
The number 90 fits into 606 6 times, leaving a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 540 from 606 and we're left with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 90

Step 4:
The number 90 fits into 663 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
The remainder is 33 after subtracting 630 from 663.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 90

On to step 5:
90 can be fit into 338 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 673.0
The remainder is 68 after subtracting 270 from 338.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 90

Step 6:
If we divide 688 by 90, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 6737.0
Subtracting 630 from 688 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
580 divided by 90 is 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 6737.6
Subtracting 540 from 580 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 6737.64
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 90 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 6737.644
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 6737.644 and a remainder of 0.004.
