Let's divide 28928889 by 515
We want to figure out the number of times 28928889 can be divided by 515.

Step 1:
2 divided by 515 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 515

On to step 2:
515 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 515

On to step 3:
515 goes into 289 0 times with a remainder of 289.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 289 and we're left with 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 515

Let's proceed to step 4:
If we divide 2892 by 515, we get 5 and a remainder of 317.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 2575 from 2892 leaves us with 317.
Append the next digit (8) from the dividend to 317 and continue with: 3178 / 515

Let's proceed to step 5:
If we divide 3178 by 515, we get 6 and a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 3090 from 3178 to get 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 515

Moving on to step 6:
When dividing 888 by 515, we get 1 with a remainder of 373.
The number 1 becomes the next digit in our result. 
Result so far: 561.0
Subtracting 515 from 888 leaves us with 373.
Grab the next digit (8) from the dividend, add it to 373, then carry on: 3738 / 515

Advancing to step 7:
515 goes into 3738 7 times with a remainder of 133.
The next digit of our result is 7. 
Result so far: 5617.0
If we take 3605 away from 3738, we end up with 133.
Grab the next digit (9) from the dividend, add it to 133, then carry on: 1339 / 515

Step 8:
1339 divided by 515 is 2 with a remainder of 309.
The next digit of our result is 2. 
Result so far: 56172.0
Deduct 1030 from 1339 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 9:
The number 515 fits into 3090 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 56172.6
Subtracting 3090 from 3090 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 515 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56172.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
515 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 56172.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 56172.6 and a remainder of 0.0.
