We're dividing 813563 by 52 
We're looking to find how many times 52 goes into 813563.

Going ahead to step 1:
The number 52 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 52

Moving on to step 2:
52 goes into 81 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 52 from 81 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 52

Step 3:
If we divide 293 by 52, we get 5 and a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 260 from 293 and we're left with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 52

Going ahead to step 4:
The number 52 fits into 335 6 times, leaving a remainder of 23.
The next digit of our result is 6. 
Result so far: 156.0
Subtracting 312 from 335 leaves us with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 52

Going ahead to step 5:
When dividing 236 by 52, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1564.0
Deduct 208 from 236 and we're left with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 52

Let's proceed to step 6:
52 can be fit into 283 5 times, resulting in a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 15645.0
Subtract 260 from 283 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
If we divide 230 by 52, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 15645.4
If we subtract 208 from 230, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
The number 52 fits into 220 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15645.44
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 15645.44 and a remainder of 0.012.
