Let's divide 28439536 by 579
We're looking to find how many times 579 goes into 28439536.

Step 1:
The number 579 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 579

Advancing to step 2:
579 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 579

Advancing to step 3:
If we divide 284 by 579, we get 0 and a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 284 and we're left with 284.
Append the next digit (3) from the dividend to 284 and continue with: 2843 / 579

Going ahead to step 4:
The number 579 fits into 2843 4 times, leaving a remainder of 527.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2316 from 2843, we get 527.
Bring next digit (9) of the dividend behind the 527 and repeat the process: 5279 / 579

Step 5:
If we divide 5279 by 579, we get 9 and a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 5211 away from 5279, we end up with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 579

Advancing to step 6:
If we divide 685 by 579, we get 1 and a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 491.0
Deduct 579 from 685 and we're left with 106.
Grab the next digit (3) from the dividend, add it to 106, then carry on: 1063 / 579

Step 7:
1063 divided by 579 is 1 with a remainder of 484.
Record the quotient 1 as the next digit in the result. 
Result so far: 4911.0
Subtract 579 from 1063 to get 484.
Take the next digit (6) from the dividend and append it to 484, then repeat: 4846 / 579

Moving on to step 8:
4846 divided by 579 is 8 with a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 49118.0
Subtracting 4632 from 4846 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 9:
2140 divided by 579 is 3 with a remainder of 403.
The next digit of our result is 3. 
Result so far: 49118.3
The remainder is 403 after subtracting 1737 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 10:
When dividing 4030 by 579, we get 6 with a remainder of 556.
Write down 6 as next digit of the result. 
Result so far: 49118.36
If we subtract 3474 from 4030, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 11:
579 can be fit into 5560 9 times, resulting in a remainder of 349.
The next digit of our result is 9. 
Result so far: 49118.369
The remainder is 349 after subtracting 5211 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Let's proceed to step 12:
The number 579 fits into 3490 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 49118.3696
If we subtract 3474 from 3490, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 579 is 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 49118.3696
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
The number 579 fits into 1600 2 times, leaving a remainder of 442.
Put 2 as the next digit of the answer. 
Result so far: 49118.369602
Subtract 1158 from 1600 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 15:
579 can be fit into 4420 7 times, resulting in a remainder of 367.
Write down 7 as next digit of the result. 
Result so far: 49118.3696027
The remainder is 367 after subtracting 4053 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 16:
When dividing 3670 by 579, we get 6 with a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 49118.36960276
Subtracting 3474 from 3670 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 49118.36960276 and a remainder of 1.96e-07.
