We look at the division of 601842 by 90 
Let's see how many times 90 fits into 601842.

On to step 1:
6 divided by 90 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 90

On to step 2:
The number 90 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 90

Let's proceed to step 3:
90 goes into 601 6 times with a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 540 from 601 leaves us with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 90

On to step 4:
618 divided by 90 is 6 with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtracting 540 from 618 leaves us with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 90

Let's proceed to step 5:
If we divide 784 by 90, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 668.0
If we take 720 away from 784, we end up with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 90

Moving on to step 6:
The number 90 fits into 642 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 6687.0
If we take 630 away from 642, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 90 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 6687.1
If we take 90 away from 120, 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.

On 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: 6687.13
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.

Advancing to step 9:
90 goes into 300 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 6687.133
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.

The final outcome is 6687.133, with a leftover of 0.003.
