We're dividing 39839243 by 349 
We're looking to find how many times 349 goes into 39839243.

Going ahead to step 1:
If we divide 3 by 349, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 349

On to step 2:
When dividing 39 by 349, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 349

Advancing to step 3:
349 can be fit into 398 1 times, resulting in a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 349 from 398 and we're left with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 349

Step 4:
When dividing 493 by 349, we get 1 with a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 349 from 493 and we're left with 144.
Bring next digit (9) of the dividend behind the 144 and repeat the process: 1449 / 349

Step 5:
If we divide 1449 by 349, we get 4 and a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 114.0
The remainder is 53 after subtracting 1396 from 1449.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 349

Step 6:
532 divided by 349 is 1 with a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 1141.0
If we subtract 349 from 532, we get 183.
Take the next digit (4) from the dividend and append it to 183, then repeat: 1834 / 349

Step 7:
1834 divided by 349 is 5 with a remainder of 89.
The number 5 becomes the next digit in our result. 
Result so far: 11415.0
Subtracting 1745 from 1834 leaves us with 89.
Bring next digit (3) of the dividend behind the 89 and repeat the process: 893 / 349

On to step 8:
If we divide 893 by 349, we get 2 and a remainder of 195.
Record the quotient 2 as the next digit in the result. 
Result so far: 114152.0
If we subtract 698 from 893, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
If we divide 1950 by 349, we get 5 and a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 114152.5
If we subtract 1745 from 1950, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 10:
If we divide 2050 by 349, we get 5 and a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 114152.55
Subtracting 1745 from 2050 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The quotient of the division is 114152.55, and the remainder is 0.305.
