We look at the division of 12887989 by 254 
We want to divide 12887989 by 254.

Step 1:
The number 254 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 254

Let's proceed to step 2:
The number 254 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 254

Step 3:
If we divide 128 by 254, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Include the next digit (8) from the dividend after 128, then repeat: 1288 / 254

Moving on to step 4:
254 goes into 1288 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 1270 from 1288 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 254

On to step 5:
When dividing 187 by 254, we get 0 with a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 187, we end up with 187.
Take the next digit (9) from the dividend and append it to 187, then repeat: 1879 / 254

Advancing to step 6:
The number 254 fits into 1879 7 times, leaving a remainder of 101.
The next digit of our result is 7. 
Result so far: 507.0
If we subtract 1778 from 1879, we get 101.
Fetch the next digit (8) from the dividend, attach it to 101 and continue: 1018 / 254

Step 7:
If we divide 1018 by 254, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5074.0
Subtract 1016 from 1018 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 254

Step 8:
If we divide 29 by 254, we get 0 and a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 50740.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
254 can be fit into 290 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 50740.1
Subtracting 254 from 290 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
254 can be fit into 360 1 times, resulting in a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 50740.11
Subtracting 254 from 360 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 50740.11 with a balance of 0.106.
