Let's divide 670123 by 18
Our goal is to divide 670123 by 18.

On to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 18

Let's proceed to step 2:
67 divided by 18 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 13 after subtracting 54 from 67.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 18

Advancing to step 3:
18 can be fit into 130 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 126 from 130 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 18

On to step 4:
When dividing 41 by 18, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 372.0
Subtract 36 from 41 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 18

Moving on to step 5:
52 divided by 18 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 3722.0
Subtract 36 from 52 to get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 18

Moving on to step 6:
The number 18 fits into 163 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 37229.0
Deduct 162 from 163 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 18 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 37229.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 18 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 37229.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
18 goes into 100 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 37229.055
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 37229.055 with a remaining 0.001.
