We're dividing 890171 by 18 
Our goal is to divide 890171 by 18.

On to step 1:
If we divide 8 by 18, we get 0 and 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.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 18

Step 2:
18 goes into 89 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 72 from 89, we get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 18

Advancing to step 3:
If we divide 170 by 18, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 162 from 170 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 18

Let's proceed to step 4:
When dividing 81 by 18, we get 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 494.0
The remainder is 9 after subtracting 72 from 81.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 18

On to step 5:
The number 18 fits into 97 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 4945.0
Subtracting 90 from 97 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 18

Let's proceed to step 6:
If we divide 71 by 18, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 49453.0
If we subtract 54 from 71, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 18 fits into 170 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 49453.9
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 18 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 49453.94
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 18, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 49453.944
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 49453.944, with a leftover of 0.0008.
