We're dividing 393965 by 53 
We want to divide 393965 by 53.

Advancing to step 1:
If we divide 3 by 53, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 53

Let's proceed to step 2:
39 divided by 53 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 53

Going ahead to step 3:
53 can be fit into 393 7 times, resulting in a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 371 from 393 to get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 53

Let's proceed to step 4:
When dividing 229 by 53, we get 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we take 212 away from 229, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 53

Advancing to step 5:
53 can be fit into 176 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 743.0
The remainder is 17 after subtracting 159 from 176.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 53

On to step 6:
If we divide 175 by 53, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 7433.0
Subtract 159 from 175 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
53 goes into 160 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 7433.3
If we take 159 away from 160, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 53, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7433.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 53 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 7433.301
If we take 53 away from 100, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 7433.3018
Subtract 424 from 470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
460 divided by 53 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 7433.30188
Subtracting 424 from 460 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 7433.30188, with a leftover of 3.6e-05.
