Let's divide 673645 by 52
We're looking to find how many times 52 goes into 673645.

Step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 52

On to step 2:
If we divide 67 by 52, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 52 from 67 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 52

Going ahead to step 3:
52 can be fit into 153 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 104 away from 153, we end up with 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 52

Advancing to step 4:
52 goes into 496 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 468 from 496 leaves us with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 52

Let's proceed to step 5:
52 goes into 284 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 1295.0
The remainder is 24 after subtracting 260 from 284.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 52

On to step 6:
52 goes into 245 4 times with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 12954.0
Subtracting 208 from 245 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
If we divide 370 by 52, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 12954.7
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 52, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 12954.71
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 52 fits into 80 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 12954.711
The remainder is 28 after subtracting 52 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 12954.711, with a leftover of 0.0028.
