We look at the division of 615373 by 45 
We're looking to find how many times 45 goes into 615373.

Let's proceed to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 45

Step 2:
61 divided by 45 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 61 leaves us with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 45

Going ahead to step 3:
45 can be fit into 165 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 135 from 165 to get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 45

On to step 4:
When dividing 303 by 45, we get 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 136.0
The remainder is 33 after subtracting 270 from 303.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 45

Step 5:
The number 45 fits into 337 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 1367.0
Deduct 315 from 337 and we're left with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 45

Let's proceed to step 6:
45 goes into 223 4 times with a remainder of 43.
The next digit of our result is 4. 
Result so far: 13674.0
Subtract 180 from 223 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
The number 45 fits into 430 9 times, leaving a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 13674.9
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
250 divided by 45 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 13674.95
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
45 goes into 250 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 13674.955
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 13674.955 with a balance of 0.0025.
