8179912 divided by 45 
Our goal is to divide 8179912 by 45.

Let's proceed to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 45

Step 2:
45 can be fit into 81 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 81, we get 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 45

Step 3:
45 goes into 367 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 360 from 367, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 45

Moving on to step 4:
If we divide 79 by 45, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we take 45 away from 79, we end up with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 45

On to step 5:
349 divided by 45 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 1817.0
If we subtract 315 from 349, we get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 45

Step 6:
45 goes into 341 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 18177.0
If we subtract 315 from 341, we get 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 45

Moving on to step 7:
45 goes into 262 5 times with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 181775.0
The remainder is 37 after subtracting 225 from 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
45 can be fit into 370 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 181775.8
If we subtract 360 from 370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 181775.82
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 45 fits into 100 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 181775.822
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 181775.822 and a remainder of 0.001.
