We're dividing 521523 by 10 
Let's see how many times 10 fits into 521523.

Advancing to step 1:
10 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 10

Let's proceed to step 2:
If we divide 52 by 10, we get 5 and a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 50 from 52, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

On to step 3:
21 divided by 10 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 1 after subtracting 20 from 21.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 10

Let's proceed to step 4:
10 can be fit into 15 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 521.0
Subtracting 10 from 15 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 10

Going ahead to step 5:
The number 10 fits into 52 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5215.0
If we take 50 away from 52, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 10

Let's proceed to step 6:
10 can be fit into 23 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 52152.0
The remainder is 3 after subtracting 20 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 10, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 52152.3
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 52152.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52152.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 52152.3 and a remainder of 0.0.
