Let's divide 339931 by 53
We want to figure out the number of times 339931 can be divided by 53.

On to step 1:
If we divide 3 by 53, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 53

On to step 2:
When dividing 33 by 53, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 53

Advancing to step 3:
339 divided by 53 is 6 with a remainder of 21.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 318 from 339 to get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 53

Let's proceed to step 4:
53 goes into 219 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 212 away from 219, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 53

Step 5:
When dividing 73 by 53, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 641.0
If we take 53 away from 73, we end up with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 53

Going ahead to step 6:
When dividing 201 by 53, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 6413.0
Subtract 159 from 201 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
53 goes into 420 7 times with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 6413.7
Subtracting 371 from 420 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 8:
The number 53 fits into 490 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 6413.79
If we subtract 477 from 490, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
When dividing 130 by 53, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 6413.792
Deduct 106 from 130 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 53 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 6413.7924
Subtract 212 from 240 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.

On to step 11:
53 goes into 280 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 6413.79245
Subtract 265 from 280 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
If we divide 150 by 53, we get 2 and a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6413.792452
If we take 106 away from 150, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
The number 53 fits into 440 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 6413.7924528
If we take 424 away from 440, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
160 divided by 53 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 6413.79245283
Deduct 159 from 160 and we're left 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.

In conclusion, the division gives 6413.79245283 with a balance of 1e-09.
