309042 ÷ 52 
We're looking to find how many times 52 goes into 309042.

Advancing to step 1:
3 divided by 52 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 52

Going ahead to step 2:
52 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 52

Let's proceed to step 3:
If we divide 309 by 52, we get 5 and a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 260 away from 309, we end up with 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 52

On to step 4:
The number 52 fits into 490 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtract 468 from 490 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 52

Moving on to step 5:
52 goes into 224 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 594.0
The remainder is 16 after subtracting 208 from 224.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 52

On to step 6:
If we divide 162 by 52, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 5943.0
If we take 156 away from 162, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
52 can be fit into 60 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 5943.1
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 52 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 5943.11
Subtract 52 from 80 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 5943.11 and a remainder of 0.028.
