We look at the division of 203990 by 8 
We want to divide 203990 by 8.

On to step 1:
2 divided by 8 is 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.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 8

Step 2:
20 divided by 8 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 16 away from 20, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 8

Going ahead to step 3:
If we divide 43 by 8, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 40 from 43 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 8

Step 4:
The number 8 fits into 39 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Deduct 32 from 39 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 8

On to step 5:
79 divided by 8 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 2549.0
If we take 72 away from 79, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 8

Moving on to step 6:
8 goes into 70 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 25498.0
If we subtract 64 from 70, 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.

Let's proceed to step 7:
8 goes into 60 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 25498.7
Subtracting 56 from 60 leaves us 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.

Going ahead to step 8:
When dividing 40 by 8, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 25498.75
Deduct 40 from 40 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.

Advancing to step 9:
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: 25498.75
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.

Step 10:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25498.75
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.

In conclusion, the division gives 25498.75 with a balance of 0.0.
