We look at the division of 28870251 by 123 
We're looking to find how many times 123 goes into 28870251.

On to step 1:
123 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 123

Going ahead to step 2:
123 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 123

Let's proceed to step 3:
123 can be fit into 288 2 times, resulting in a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 246 from 288, we get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 123

On to step 4:
123 can be fit into 427 3 times, resulting in a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 369 from 427, we get 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 123

Going ahead to step 5:
580 divided by 123 is 4 with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 234.0
The remainder is 88 after subtracting 492 from 580.
Fetch the next digit (2) from the dividend, attach it to 88 and continue: 882 / 123

Let's proceed to step 6:
882 divided by 123 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 2347.0
The remainder is 21 after subtracting 861 from 882.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 123

Step 7:
123 goes into 215 1 times with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 23471.0
Subtract 123 from 215 to get 92.
Fetch the next digit (1) from the dividend, attach it to 92 and continue: 921 / 123

On to step 8:
123 goes into 921 7 times with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 234717.0
The remainder is 60 after subtracting 861 from 921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 123, we get 4 with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 234717.4
If we take 492 away from 600, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 10:
123 goes into 1080 8 times with a remainder of 96.
The next digit of our result is 8. 
Result so far: 234717.48
Subtract 984 from 1080 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
If we divide 960 by 123, we get 7 and a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 234717.487
The remainder is 99 after subtracting 861 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 12:
The number 123 fits into 990 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 234717.4878
If we take 984 away from 990, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
The number 123 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 234717.4878
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
When dividing 600 by 123, we get 4 with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 234717.487804
Deduct 492 from 600 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 15:
1080 divided by 123 is 8 with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 234717.4878048
Subtract 984 from 1080 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 16:
If we divide 960 by 123, we get 7 and a remainder of 99.
The next digit of our result is 7. 
Result so far: 234717.48780487
Deduct 861 from 960 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Our division results in 234717.48780487 with a remaining 9.9e-08.
