We look at the division of 307580 by 45 
We want to figure out the number of times 307580 can be divided by 45.

Step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
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 2:
45 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 45

Going ahead to step 3:
If we divide 307 by 45, we get 6 and a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 270 from 307 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 45

Advancing to step 4:
45 goes into 375 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtracting 360 from 375 leaves us with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 45

Let's proceed to step 5:
When dividing 158 by 45, we get 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 683.0
If we take 135 away from 158, we end up with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 45

On to step 6:
When dividing 230 by 45, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6835.0
Subtract 225 from 230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
45 goes into 50 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 6835.1
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 6835.11
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 6835.11 with a balance of 0.005.
