579151 divided by 45 
Our goal is to divide 579151 by 45.

Advancing to step 1:
45 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 45

Let's proceed to step 2:
The number 45 fits into 57 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 45

On to step 3:
45 can be fit into 129 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 90 from 129 leaves us with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 45

Going ahead to step 4:
45 can be fit into 391 8 times, resulting in a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 360 from 391, we get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 45

Step 5:
315 divided by 45 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1287.0
The remainder is 0 after subtracting 315 from 315.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 45

Let's proceed to step 6:
45 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 12870.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 45, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12870.0
Subtract 0 from 10 to 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.

Step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12870.02
Subtract 90 from 100 to 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.

Step 9:
The number 45 fits into 100 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 12870.022
Deduct 90 from 100 and we're left 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.

The final outcome is 12870.022, with a leftover of 0.001.
