Let's divide 75318728 by 45
We're looking to find how many times 45 goes into 75318728.

Step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 45

Advancing to step 2:
When dividing 75 by 45, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 75 to get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 45

On to step 3:
303 divided by 45 is 6 with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 270 from 303 to get 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 45

Moving on to step 4:
When dividing 331 by 45, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Subtracting 315 from 331 leaves us with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 45

On to step 5:
45 can be fit into 168 3 times, resulting in a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 1673.0
Deduct 135 from 168 and we're left with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 45

Going ahead to step 6:
45 goes into 337 7 times with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 16737.0
Subtracting 315 from 337 leaves us with 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 45

Step 7:
When dividing 222 by 45, we get 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 167374.0
Subtracting 180 from 222 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 45

Let's proceed to step 8:
428 divided by 45 is 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 1673749.0
Deduct 405 from 428 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
If we divide 230 by 45, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1673749.5
Subtracting 225 from 230 leaves us with 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 10:
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: 1673749.51
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.

Advancing to step 11:
50 divided by 45 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1673749.511
If we take 45 away from 50, we end up with 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 1673749.511 with a balance of 0.0005.
