Let's divide 525039 by 45
Our goal is to divide 525039 by 45.

Step 1:
45 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 45

Advancing to step 2:
45 can be fit into 52 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 7 after subtracting 45 from 52.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 45

Step 3:
75 divided by 45 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 45 from 75 and we're left with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 45

Step 4:
If we divide 300 by 45, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 116.0
Deduct 270 from 300 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 45

Let's proceed to step 5:
45 goes into 303 6 times with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 1166.0
If we take 270 away from 303, we end up with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 45

Going ahead to step 6:
If we divide 339 by 45, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 11667.0
Subtracting 315 from 339 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.

Going ahead to step 7:
45 can be fit into 240 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 11667.5
If we take 225 away from 240, we end up 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 8:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 11667.53
The remainder is 15 after subtracting 135 from 150.
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:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 11667.533
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 11667.533 with a remainder of 0.0015.
