903012 divided by 45 
Our goal is to divide 903012 by 45.

Moving on to step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 45

Let's proceed to step 2:
If we divide 90 by 45, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 90 from 90 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 45

On to step 3:
If we divide 3 by 45, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 45

Going ahead to step 4:
If we divide 30 by 45, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 200.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 45

Let's proceed to step 5:
When dividing 301 by 45, we get 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 2006.0
Deduct 270 from 301 and we're left with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 45

Moving on to step 6:
The number 45 fits into 312 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 20066.0
If we take 270 away from 312, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
420 divided by 45 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 20066.9
If we subtract 405 from 420, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 20066.93
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 45 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 20066.933
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 20066.933 with a balance of 0.0015.
