We're dividing 339506 by 53 
We want to divide 339506 by 53.

Step 1:
53 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 53

Advancing to step 2:
If we divide 33 by 53, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 53

Going ahead to step 3:
53 goes into 339 6 times with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 318 from 339 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 53

On to step 4:
The number 53 fits into 215 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 212 from 215, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 53

Let's proceed to step 5:
The number 53 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 640.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 53

Step 6:
53 goes into 306 5 times with a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 6405.0
Subtract 265 from 306 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.

On to step 7:
53 can be fit into 410 7 times, resulting in a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 6405.7
Subtract 371 from 410 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
53 can be fit into 390 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 6405.77
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 6405.77, with a leftover of 0.019.
