49591209 ÷ 339 
We want to figure out the number of times 49591209 can be divided by 339.

Step 1:
4 divided by 339 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 339

Step 2:
If we divide 49 by 339, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 339

Going ahead to step 3:
495 divided by 339 is 1 with a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 339 from 495 and we're left with 156.
Bring next digit (9) of the dividend behind the 156 and repeat the process: 1569 / 339

Going ahead to step 4:
1569 divided by 339 is 4 with a remainder of 213.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 1356 from 1569, we get 213.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 339

Advancing to step 5:
When dividing 2131 by 339, we get 6 with a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Subtracting 2034 from 2131 leaves us with 97.
Append the next digit (2) from the dividend to 97 and continue with: 972 / 339

Let's proceed to step 6:
When dividing 972 by 339, we get 2 with a remainder of 294.
Use 2 as the next digit of our solution. 
Result so far: 1462.0
If we take 678 away from 972, we end up with 294.
Take the next digit (0) from the dividend and append it to 294, then repeat: 2940 / 339

On to step 7:
339 goes into 2940 8 times with a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 14628.0
Deduct 2712 from 2940 and we're left with 228.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 339

Going ahead to step 8:
The number 339 fits into 2289 6 times, leaving a remainder of 255.
Write down 6 as next digit of the result. 
Result so far: 146286.0
Subtract 2034 from 2289 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
339 can be fit into 2550 7 times, resulting in a remainder of 177.
Put 7 as the next digit of the answer. 
Result so far: 146286.7
Subtract 2373 from 2550 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 10:
When dividing 1770 by 339, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 146286.75
If we subtract 1695 from 1770, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
750 divided by 339 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 146286.752
Deduct 678 from 750 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
339 goes into 720 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 146286.7522
The remainder is 42 after subtracting 678 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 146286.7522, and the remainder is 0.00042.
