39012990 divided by 343 
Let's see how many times 343 fits into 39012990.

Advancing to step 1:
If we divide 3 by 343, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 343

Going ahead to step 2:
343 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 343

Going ahead to step 3:
343 can be fit into 390 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 343 from 390, we get 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 343

Going ahead to step 4:
471 divided by 343 is 1 with a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 128 after subtracting 343 from 471.
Fetch the next digit (2) from the dividend, attach it to 128 and continue: 1282 / 343

Advancing to step 5:
1282 divided by 343 is 3 with a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 113.0
If we subtract 1029 from 1282, we get 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 343

Let's proceed to step 6:
343 can be fit into 2539 7 times, resulting in a remainder of 138.
Write down 7 as next digit of the result. 
Result so far: 1137.0
If we take 2401 away from 2539, we end up with 138.
Grab the next digit (9) from the dividend, add it to 138, then carry on: 1389 / 343

Moving on to step 7:
If we divide 1389 by 343, we get 4 and a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 11374.0
Deduct 1372 from 1389 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 343

Let's proceed to step 8:
When dividing 170 by 343, we get 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 113740.0
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
The number 343 fits into 1700 4 times, leaving a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 113740.4
Subtracting 1372 from 1700 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
343 can be fit into 3280 9 times, resulting in a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 113740.49
Subtract 3087 from 3280 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 11:
The number 343 fits into 1930 5 times, leaving a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 113740.495
Subtracting 1715 from 1930 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 12:
343 goes into 2150 6 times with a remainder of 92.
The next digit of our result is 6. 
Result so far: 113740.4956
Subtract 2058 from 2150 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
The number 343 fits into 920 2 times, leaving a remainder of 234.
The number 2 becomes the next digit in our result. 
Result so far: 113740.49562
Subtract 686 from 920 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 14:
If we divide 2340 by 343, we get 6 and a remainder of 282.
Write down 6 as next digit of the result. 
Result so far: 113740.495626
Subtracting 2058 from 2340 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 15:
If we divide 2820 by 343, we get 8 and a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 113740.4956268
The remainder is 76 after subtracting 2744 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 16:
760 divided by 343 is 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 113740.49562682
Deduct 686 from 760 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 113740.49562682 with a remainder of 7.4e-08.
