Let's divide 203987 by 8
Let's see how many times 8 fits into 203987.

Going ahead to step 1:
When dividing 2 by 8, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 8

Moving on to step 2:
If we divide 20 by 8, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 16 from 20, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

Moving on to step 3:
The number 8 fits into 43 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 3 after subtracting 40 from 43.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 8

Let's proceed to step 4:
39 divided by 8 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
If we take 32 away from 39, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 8

Going ahead to step 5:
The number 8 fits into 78 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2549.0
Deduct 72 from 78 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 8

Advancing to step 6:
The number 8 fits into 67 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 25498.0
If we subtract 64 from 67, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 25498.3
If we subtract 24 from 30, we get 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 8:
8 goes into 60 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 25498.37
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25498.375
Subtract 40 from 40 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.

Moving on to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25498.375
Subtracting 0 from 0 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 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25498.375
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 25498.375, with a leftover of 0.0.
