642929 divided by 18 
Our goal is to divide 642929 by 18.

Let's proceed to step 1:
6 divided by 18 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 18

Moving on to step 2:
18 goes into 64 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 54 away from 64, we end up with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 18

Going ahead to step 3:
If we divide 102 by 18, we get 5 and a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 90 from 102 leaves us with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 18

On to step 4:
If we divide 129 by 18, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 357.0
Deduct 126 from 129 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 18

Moving on to step 5:
The number 18 fits into 32 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3571.0
If we subtract 18 from 32, we get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 18

Let's proceed to step 6:
If we divide 149 by 18, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 35718.0
Subtracting 144 from 149 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 18 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 35718.2
If we subtract 36 from 50, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 35718.27
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
When dividing 140 by 18, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 35718.277
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 35718.277, and the remainder is 0.0014.
