439138 divided by 53 
Let's see how many times 53 fits into 439138.

Moving on to step 1:
If we divide 4 by 53, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 53

Let's proceed to step 2:
When dividing 43 by 53, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 53

Advancing to step 3:
If we divide 439 by 53, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 424 from 439 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 53

Moving on to step 4:
151 divided by 53 is 2 with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 106 from 151 leaves us with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 53

Moving on to step 5:
If we divide 453 by 53, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 828.0
Deduct 424 from 453 and we're left with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 53

Let's proceed to step 6:
53 can be fit into 298 5 times, resulting in a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 8285.0
If we take 265 away from 298, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
53 goes into 330 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 8285.6
If we take 318 away from 330, we end up 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.

Advancing to step 8:
If we divide 120 by 53, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 8285.62
The remainder is 14 after subtracting 106 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
When dividing 140 by 53, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 8285.622
Deduct 106 from 140 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 8285.622, with a leftover of 0.0034.
