We're dividing 28890146 by 800 
We want to divide 28890146 by 800.

Step 1:
If we divide 2 by 800, we get 0 and 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 / 800

Moving on to step 2:
If we divide 28 by 800, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 800

Step 3:
288 divided by 800 is 0 with a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Bring next digit (9) of the dividend behind the 288 and repeat the process: 2889 / 800

Going ahead to step 4:
If we divide 2889 by 800, we get 3 and a remainder of 489.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2400 from 2889 and we're left with 489.
Include the next digit (0) from the dividend after 489, then repeat: 4890 / 800

Going ahead to step 5:
If we divide 4890 by 800, we get 6 and a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 4800 from 4890, we get 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 800

Step 6:
901 divided by 800 is 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 361.0
If we take 800 away from 901, we end up with 101.
Take the next digit (4) from the dividend and append it to 101, then repeat: 1014 / 800

Let's proceed to step 7:
1014 divided by 800 is 1 with a remainder of 214.
The number 1 becomes the next digit in our result. 
Result so far: 3611.0
The remainder is 214 after subtracting 800 from 1014.
Append the next digit (6) from the dividend to 214 and continue with: 2146 / 800

Advancing to step 8:
800 can be fit into 2146 2 times, resulting in a remainder of 546.
Put 2 as the next digit of the answer. 
Result so far: 36112.0
The remainder is 546 after subtracting 1600 from 2146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 9:
When dividing 5460 by 800, we get 6 with a remainder of 660.
Record the quotient 6 as the next digit in the result. 
Result so far: 36112.6
The remainder is 660 after subtracting 4800 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 10:
800 goes into 6600 8 times with a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 36112.68
Deduct 6400 from 6600 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
800 goes into 2000 2 times with a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 36112.682
If we subtract 1600 from 2000, we 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 12:
800 goes into 4000 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 36112.6825
Subtracting 4000 from 4000 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.

Moving on to step 13:
When dividing 0 by 800, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36112.6825
If we take 0 away from 0, we end up 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.

Moving on to step 14:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36112.6825
Deduct 0 from 0 and we're left 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.

The final outcome is 36112.6825, with a leftover of 0.0.
