We look at the division of 524121 by 13 
Let's see how many times 13 fits into 524121.

Advancing to step 1:
13 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 13

Step 2:
13 goes into 52 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 52 from 52 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 13

Let's proceed to step 3:
When dividing 4 by 13, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 13

On to step 4:
The number 13 fits into 41 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 403.0
If we subtract 39 from 41, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 13

Step 5:
13 goes into 22 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 4031.0
If we subtract 13 from 22, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 13

Moving on to step 6:
The number 13 fits into 91 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 40317.0
Subtract 91 from 91 to 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.

On to step 7:
When dividing 0 by 13, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40317.0
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.

Going ahead to step 8:
The number 13 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40317.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 40317.0 and a remainder of 0.0.
