We divide 684144 by 53
We're looking to find how many times 53 goes into 684144.

Moving on to step 1:
53 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 53

On to step 2:
When dividing 68 by 53, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 53 from 68 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 53

Advancing to step 3:
When dividing 154 by 53, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 106 away from 154, we end up with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 53

Step 4:
If we divide 481 by 53, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 477 from 481 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 53

Let's proceed to step 5:
When dividing 44 by 53, we get 0 with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 1290.0
The remainder is 44 after subtracting 0 from 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 53

Let's proceed to step 6:
53 can be fit into 444 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 12908.0
Subtracting 424 from 444 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
53 goes into 200 3 times with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 12908.3
Subtract 159 from 200 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
53 goes into 410 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 12908.37
The remainder is 39 after subtracting 371 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
53 goes into 390 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 12908.377
If we subtract 371 from 390, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 12908.377, with a leftover of 0.0019.
