We're dividing 28541986 by 510 
We want to figure out the number of times 28541986 can be divided by 510.

On to step 1:
510 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 510

Advancing to step 2:
510 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 510

Step 3:
510 goes into 285 0 times with a remainder of 285.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 285, we get 285.
Grab the next digit (4) from the dividend, add it to 285, then carry on: 2854 / 510

Advancing to step 4:
When dividing 2854 by 510, we get 5 with a remainder of 304.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 2550 away from 2854, we end up with 304.
Fetch the next digit (1) from the dividend, attach it to 304 and continue: 3041 / 510

On to step 5:
The number 510 fits into 3041 5 times, leaving a remainder of 491.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 2550 from 3041 to get 491.
Fetch the next digit (9) from the dividend, attach it to 491 and continue: 4919 / 510

Moving on to step 6:
The number 510 fits into 4919 9 times, leaving a remainder of 329.
Use 9 as the next digit of our solution. 
Result so far: 559.0
The remainder is 329 after subtracting 4590 from 4919.
Take the next digit (8) from the dividend and append it to 329, then repeat: 3298 / 510

Let's proceed to step 7:
510 goes into 3298 6 times with a remainder of 238.
Use 6 as the next digit of our solution. 
Result so far: 5596.0
Deduct 3060 from 3298 and we're left with 238.
Take the next digit (6) from the dividend and append it to 238, then repeat: 2386 / 510

Advancing to step 8:
If we divide 2386 by 510, we get 4 and a remainder of 346.
Write down 4 as next digit of the result. 
Result so far: 55964.0
The remainder is 346 after subtracting 2040 from 2386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 9:
510 goes into 3460 6 times with a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 55964.6
Subtract 3060 from 3460 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
When dividing 4000 by 510, we get 7 with a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 55964.67
The remainder is 430 after subtracting 3570 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 11:
The number 510 fits into 4300 8 times, leaving a remainder of 220.
Record the quotient 8 as the next digit in the result. 
Result so far: 55964.678
Deduct 4080 from 4300 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
510 goes into 2200 4 times with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 55964.6784
Subtract 2040 from 2200 to 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.

Moving on to step 13:
The number 510 fits into 1600 3 times, leaving a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 55964.67843
Subtract 1530 from 1600 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
700 divided by 510 is 1 with a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 55964.678431
If we subtract 510 from 700, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 15:
If we divide 1900 by 510, we get 3 and a remainder of 370.
The next digit of our result is 3. 
Result so far: 55964.6784313
Deduct 1530 from 1900 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 16:
510 goes into 3700 7 times with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 55964.67843137
If we take 3570 away from 3700, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 55964.67843137, with a leftover of 1.3e-07.
