669523 ÷ 45 
We want to divide 669523 by 45.

On to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 45

Let's proceed to step 2:
The number 45 fits into 66 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 21 after subtracting 45 from 66.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 45

Going ahead to step 3:
The number 45 fits into 219 4 times, leaving a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 180 from 219, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 45

Step 4:
395 divided by 45 is 8 with a remainder of 35.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 360 from 395 and we're left with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 45

Going ahead to step 5:
If we divide 352 by 45, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 1487.0
The remainder is 37 after subtracting 315 from 352.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 45

Step 6:
373 divided by 45 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 14878.0
Subtracting 360 from 373 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 45, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 14878.2
Deduct 90 from 130 and we're left 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.

Moving on to step 8:
400 divided by 45 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 14878.28
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 14878.288
Subtracting 360 from 400 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.

In conclusion, the division gives 14878.288 with a balance of 0.004.
