We divide 645031 by 52
We want to figure out the number of times 645031 can be divided by 52.

Going ahead to step 1:
52 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 52

On to step 2:
When dividing 64 by 52, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 52 from 64 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 52

Let's proceed to step 3:
If we divide 125 by 52, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 104 away from 125, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 52

Step 4:
210 divided by 52 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 208 away from 210, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 52

On to step 5:
52 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 1240.0
Subtract 0 from 23 to get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 52

Let's proceed to step 6:
52 can be fit into 231 4 times, resulting in a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 12404.0
Subtract 208 from 231 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.

Moving on to step 7:
When dividing 230 by 52, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 12404.4
Subtracting 208 from 230 leaves us with 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:
52 goes into 220 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 12404.44
Deduct 208 from 220 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 12404.44 with a remaining 0.012.
