We're dividing 665594 by 45 
We want to divide 665594 by 45.

Moving on to step 1:
If we divide 6 by 45, we get 0 and 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 (6) from the dividend, attach it to 6 and continue: 66 / 45

Advancing to step 2:
The number 45 fits into 66 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 66 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 45

Going ahead to step 3:
45 goes into 215 4 times with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 180 from 215 and we're left with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 45

Step 4:
The number 45 fits into 355 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 147.0
Subtract 315 from 355 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 45

On to step 5:
If we divide 409 by 45, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 1479.0
If we take 405 away from 409, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 45

Advancing to step 6:
The number 45 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 14790.0
Deduct 0 from 44 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
The number 45 fits into 440 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 14790.9
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
45 goes into 350 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 14790.97
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 14790.977
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 14790.977 with a remaining 0.0035.
