We're dividing 30074339 by 45 
Let's see how many times 45 fits into 30074339.

Advancing to step 1:
If we divide 3 by 45, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 45

Step 2:
45 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 45

Moving on to step 3:
The number 45 fits into 300 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 270 from 300 and we're left with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 45

Advancing to step 4:
If we divide 307 by 45, we get 6 and a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 270 away from 307, we end up with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 45

On to step 5:
45 can be fit into 374 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 668.0
Subtracting 360 from 374 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 45

Going ahead to step 6:
45 can be fit into 143 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 6683.0
Subtract 135 from 143 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 45

On to step 7:
83 divided by 45 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 66831.0
The remainder is 38 after subtracting 45 from 83.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 45

Going ahead to step 8:
389 divided by 45 is 8 with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 668318.0
Subtracting 360 from 389 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
If we divide 290 by 45, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 668318.6
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 668318.64
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 668318.644
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 668318.644 with a balance of 0.002.
