We're dividing 83799980 by 587 
We're looking to find how many times 587 goes into 83799980.

Moving on to step 1:
587 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 587

Advancing to step 2:
If we divide 83 by 587, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 587

Let's proceed to step 3:
If we divide 837 by 587, we get 1 and a remainder of 250.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 587 from 837 leaves us with 250.
Include the next digit (9) from the dividend after 250, then repeat: 2509 / 587

Going ahead to step 4:
587 can be fit into 2509 4 times, resulting in a remainder of 161.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 2348 away from 2509, we end up with 161.
Grab the next digit (9) from the dividend, add it to 161, then carry on: 1619 / 587

Advancing to step 5:
587 goes into 1619 2 times with a remainder of 445.
The next digit of our result is 2. 
Result so far: 142.0
If we take 1174 away from 1619, we end up with 445.
Bring next digit (9) of the dividend behind the 445 and repeat the process: 4459 / 587

Going ahead to step 6:
If we divide 4459 by 587, we get 7 and a remainder of 350.
Write down 7 as next digit of the result. 
Result so far: 1427.0
The remainder is 350 after subtracting 4109 from 4459.
Bring next digit (8) of the dividend behind the 350 and repeat the process: 3508 / 587

Moving on to step 7:
3508 divided by 587 is 5 with a remainder of 573.
Use 5 as the next digit of our solution. 
Result so far: 14275.0
If we subtract 2935 from 3508, we get 573.
Include the next digit (0) from the dividend after 573, then repeat: 5730 / 587

Let's proceed to step 8:
When dividing 5730 by 587, we get 9 with a remainder of 447.
Use 9 as the next digit of our solution. 
Result so far: 142759.0
Deduct 5283 from 5730 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 9:
587 goes into 4470 7 times with a remainder of 361.
Use 7 as the next digit of our solution. 
Result so far: 142759.7
Subtract 4109 from 4470 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 10:
When dividing 3610 by 587, we get 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 142759.76
Subtracting 3522 from 3610 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.

Step 11:
If we divide 880 by 587, we get 1 and a remainder of 293.
Use 1 as the next digit of our solution. 
Result so far: 142759.761
Deduct 587 from 880 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 12:
587 can be fit into 2930 4 times, resulting in a remainder of 582.
The next digit of our result is 4. 
Result so far: 142759.7614
If we subtract 2348 from 2930, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 13:
587 goes into 5820 9 times with a remainder of 537.
The number 9 becomes the next digit in our result. 
Result so far: 142759.76149
Subtracting 5283 from 5820 leaves us with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 14:
The number 587 fits into 5370 9 times, leaving a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 142759.761499
If we subtract 5283 from 5370, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 142759.761499 and a remainder of 8.7e-06.
