We're dividing 521574 by 45 
Our goal is to divide 521574 by 45.

Moving on to step 1:
45 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 45

Step 2:
52 divided by 45 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 52 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 45

Moving on to step 3:
If we divide 71 by 45, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 45 away from 71, we end up with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 45

Step 4:
If we divide 265 by 45, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 115.0
The remainder is 40 after subtracting 225 from 265.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 45

Step 5:
407 divided by 45 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1159.0
The remainder is 2 after subtracting 405 from 407.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 45

Step 6:
45 goes into 24 0 times with a remainder of 24.
The next digit of our result is 0. 
Result so far: 11590.0
Subtracting 0 from 24 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 45, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 11590.5
If we subtract 225 from 240, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 11590.53
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 11590.533
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 11590.533 with a remaining 0.0015.
