We're dividing 28728766 by 839 
We're looking to find how many times 839 goes into 28728766.

Moving on to step 1:
If we divide 2 by 839, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 839

Going ahead to step 2:
839 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 839

Step 3:
If we divide 287 by 839, we get 0 and a remainder of 287.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 287, we end up with 287.
Fetch the next digit (2) from the dividend, attach it to 287 and continue: 2872 / 839

Going ahead to step 4:
If we divide 2872 by 839, we get 3 and a remainder of 355.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2517 from 2872, we get 355.
Include the next digit (8) from the dividend after 355, then repeat: 3558 / 839

Advancing to step 5:
839 goes into 3558 4 times with a remainder of 202.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 3356 away from 3558, we end up with 202.
Bring next digit (7) of the dividend behind the 202 and repeat the process: 2027 / 839

Advancing to step 6:
When dividing 2027 by 839, we get 2 with a remainder of 349.
Put 2 as the next digit of the answer. 
Result so far: 342.0
If we subtract 1678 from 2027, we get 349.
Fetch the next digit (6) from the dividend, attach it to 349 and continue: 3496 / 839

Going ahead to step 7:
The number 839 fits into 3496 4 times, leaving a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 3424.0
The remainder is 140 after subtracting 3356 from 3496.
Fetch the next digit (6) from the dividend, attach it to 140 and continue: 1406 / 839

Let's proceed to step 8:
The number 839 fits into 1406 1 times, leaving a remainder of 567.
Put 1 as the next digit of the answer. 
Result so far: 34241.0
Subtract 839 from 1406 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 9:
839 can be fit into 5670 6 times, resulting in a remainder of 636.
The next digit of our result is 6. 
Result so far: 34241.6
If we subtract 5034 from 5670, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 10:
839 goes into 6360 7 times with a remainder of 487.
Use 7 as the next digit of our solution. 
Result so far: 34241.67
Subtracting 5873 from 6360 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Moving on to step 11:
4870 divided by 839 is 5 with a remainder of 675.
Put 5 as the next digit of the answer. 
Result so far: 34241.675
If we take 4195 away from 4870, we end up with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 12:
If we divide 6750 by 839, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 34241.6758
Deduct 6712 from 6750 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
380 divided by 839 is 0 with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 34241.6758
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
The number 839 fits into 3800 4 times, leaving a remainder of 444.
The next digit of our result is 4. 
Result so far: 34241.675804
If we subtract 3356 from 3800, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 15:
When dividing 4440 by 839, we get 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 34241.6758045
Deduct 4195 from 4440 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 16:
2450 divided by 839 is 2 with a remainder of 772.
Put 2 as the next digit of the answer. 
Result so far: 34241.67580452
Deduct 1678 from 2450 and we're left with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

After the division, we end up with 34241.67580452 and a remainder of 7.72e-07.
