We look at the division of 43983071 by 579 
Let's see how many times 579 fits into 43983071.

Going ahead to step 1:
If we divide 4 by 579, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 579

Let's proceed to step 2:
If we divide 43 by 579, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 579

Going ahead to step 3:
579 can be fit into 439 0 times, resulting in a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 439 and we're left with 439.
Include the next digit (8) from the dividend after 439, then repeat: 4398 / 579

Moving on to step 4:
4398 divided by 579 is 7 with a remainder of 345.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4053 from 4398, we get 345.
Take the next digit (3) from the dividend and append it to 345, then repeat: 3453 / 579

Moving on to step 5:
The number 579 fits into 3453 5 times, leaving a remainder of 558.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 2895 away from 3453, we end up with 558.
Bring next digit (0) of the dividend behind the 558 and repeat the process: 5580 / 579

Moving on to step 6:
5580 divided by 579 is 9 with a remainder of 369.
Put 9 as the next digit of the answer. 
Result so far: 759.0
If we subtract 5211 from 5580, we get 369.
Grab the next digit (7) from the dividend, add it to 369, then carry on: 3697 / 579

Going ahead to step 7:
If we divide 3697 by 579, we get 6 and a remainder of 223.
The next digit of our result is 6. 
Result so far: 7596.0
If we subtract 3474 from 3697, we get 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 579

Step 8:
When dividing 2231 by 579, we get 3 with a remainder of 494.
Use 3 as the next digit of our solution. 
Result so far: 75963.0
If we subtract 1737 from 2231, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 9:
579 goes into 4940 8 times with a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 75963.8
If we subtract 4632 from 4940, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 10:
If we divide 3080 by 579, we get 5 and a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 75963.85
Subtracting 2895 from 3080 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 11:
579 can be fit into 1850 3 times, resulting in a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 75963.853
If we take 1737 away from 1850, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 12:
579 goes into 1130 1 times with a remainder of 551.
The next digit of our result is 1. 
Result so far: 75963.8531
The remainder is 551 after subtracting 579 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 13:
579 goes into 5510 9 times with a remainder of 299.
The next digit of our result is 9. 
Result so far: 75963.85319
Subtracting 5211 from 5510 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 14:
The number 579 fits into 2990 5 times, leaving a remainder of 95.
The next digit of our result is 5. 
Result so far: 75963.853195
The remainder is 95 after subtracting 2895 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 15:
When dividing 950 by 579, we get 1 with a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 75963.8531951
Subtract 579 from 950 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Going ahead to step 16:
The number 579 fits into 3710 6 times, leaving a remainder of 236.
Write down 6 as next digit of the result. 
Result so far: 75963.85319516
The remainder is 236 after subtracting 3474 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final result is 75963.85319516 with a remainder of 2.36e-07.
