43977142 divided by 339 
We want to figure out the number of times 43977142 can be divided by 339.

Step 1:
339 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 339

Let's proceed to step 2:
43 divided by 339 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 339

Step 3:
When dividing 439 by 339, we get 1 with a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 339 away from 439, we end up with 100.
Fetch the next digit (7) from the dividend, attach it to 100 and continue: 1007 / 339

Let's proceed to step 4:
The number 339 fits into 1007 2 times, leaving a remainder of 329.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 678 away from 1007, we end up with 329.
Grab the next digit (7) from the dividend, add it to 329, then carry on: 3297 / 339

Advancing to step 5:
3297 divided by 339 is 9 with a remainder of 246.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 3051 from 3297 leaves us with 246.
Fetch the next digit (1) from the dividend, attach it to 246 and continue: 2461 / 339

Advancing to step 6:
2461 divided by 339 is 7 with a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 1297.0
The remainder is 88 after subtracting 2373 from 2461.
Append the next digit (4) from the dividend to 88 and continue with: 884 / 339

Moving on to step 7:
884 divided by 339 is 2 with a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 12972.0
The remainder is 206 after subtracting 678 from 884.
Include the next digit (2) from the dividend after 206, then repeat: 2062 / 339

On to step 8:
339 can be fit into 2062 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 129726.0
Deduct 2034 from 2062 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 339 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 129726.0
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 10:
When dividing 2800 by 339, we get 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 129726.08
Subtracting 2712 from 2800 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
When dividing 880 by 339, we get 2 with a remainder of 202.
The next digit of our result is 2. 
Result so far: 129726.082
If we take 678 away from 880, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 12:
When dividing 2020 by 339, we get 5 with a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 129726.0825
Subtracting 1695 from 2020 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 13:
If we divide 3250 by 339, we get 9 and a remainder of 199.
The next digit of our result is 9. 
Result so far: 129726.08259
Subtract 3051 from 3250 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 14:
When dividing 1990 by 339, we get 5 with a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 129726.082595
The remainder is 295 after subtracting 1695 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 15:
2950 divided by 339 is 8 with a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 129726.0825958
Deduct 2712 from 2950 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 16:
If we divide 2380 by 339, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 129726.08259587
Deduct 2373 from 2380 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 129726.08259587 with a balance of 7e-09.
