Let's divide 43607939 by 310
We're looking to find how many times 310 goes into 43607939.

Moving on to step 1:
The number 310 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 310

Step 2:
The number 310 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 310

Step 3:
The number 310 fits into 436 1 times, leaving a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 310 from 436 leaves us with 126.
Fetch the next digit (0) from the dividend, attach it to 126 and continue: 1260 / 310

Let's proceed to step 4:
1260 divided by 310 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1240 from 1260 to get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 310

Moving on to step 5:
310 goes into 207 0 times with a remainder of 207.
Put 0 as the next digit of the answer. 
Result so far: 140.0
Subtracting 0 from 207 leaves us with 207.
Grab the next digit (9) from the dividend, add it to 207, then carry on: 2079 / 310

On to step 6:
If we divide 2079 by 310, we get 6 and a remainder of 219.
The next digit of our result is 6. 
Result so far: 1406.0
Subtract 1860 from 2079 to get 219.
Fetch the next digit (3) from the dividend, attach it to 219 and continue: 2193 / 310

Moving on to step 7:
The number 310 fits into 2193 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 14067.0
Subtract 2170 from 2193 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 310

Step 8:
239 divided by 310 is 0 with a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 140670.0
Deduct 0 from 239 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
2390 divided by 310 is 7 with a remainder of 220.
Put 7 as the next digit of the answer. 
Result so far: 140670.7
If we subtract 2170 from 2390, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
When dividing 2200 by 310, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 140670.77
If we subtract 2170 from 2200, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 140670.77 with a remaining 0.03.
