We look at the division of 85438392 by 203 
Let's see how many times 203 fits into 85438392.

On to step 1:
When dividing 8 by 203, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 203

On to step 2:
85 divided by 203 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 203

Moving on to step 3:
203 can be fit into 854 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 812 from 854 leaves us with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 203

Let's proceed to step 4:
203 can be fit into 423 2 times, resulting in a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 406 from 423, we get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 203

On to step 5:
203 can be fit into 178 0 times, resulting in a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 420.0
If we subtract 0 from 178, we get 178.
Take the next digit (3) from the dividend and append it to 178, then repeat: 1783 / 203

Step 6:
1783 divided by 203 is 8 with a remainder of 159.
The next digit of our result is 8. 
Result so far: 4208.0
Subtracting 1624 from 1783 leaves us with 159.
Append the next digit (9) from the dividend to 159 and continue with: 1599 / 203

On to step 7:
When dividing 1599 by 203, we get 7 with a remainder of 178.
Write down 7 as next digit of the result. 
Result so far: 42087.0
Deduct 1421 from 1599 and we're left with 178.
Include the next digit (2) from the dividend after 178, then repeat: 1782 / 203

Step 8:
1782 divided by 203 is 8 with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 420878.0
Deduct 1624 from 1782 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
The number 203 fits into 1580 7 times, leaving a remainder of 159.
The next digit of our result is 7. 
Result so far: 420878.7
If we take 1421 away from 1580, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 10:
When dividing 1590 by 203, we get 7 with a remainder of 169.
Put 7 as the next digit of the answer. 
Result so far: 420878.77
If we subtract 1421 from 1590, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

After the division, we end up with 420878.77 and a remainder of 0.169.
