We divide 646473 by 18
We want to divide 646473 by 18.

Moving on to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Moving on to step 2:
18 can be fit into 64 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 54 away from 64, we end up with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 18

Let's proceed to step 3:
18 goes into 106 5 times with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 16 after subtracting 90 from 106.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 18

Step 4:
If we divide 164 by 18, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 359.0
Deduct 162 from 164 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 18

Going ahead to step 5:
When dividing 27 by 18, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 3591.0
Deduct 18 from 27 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 18

Moving on to step 6:
93 divided by 18 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 35915.0
Subtract 90 from 93 to 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.

Going ahead to step 7:
The number 18 fits into 30 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 35915.1
If we subtract 18 from 30, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 35915.16
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
18 goes into 120 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 35915.166
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 35915.166 and a remainder of 0.0012.
