We divide 66341056 by 18
Let's see how many times 18 fits into 66341056.

Going ahead to step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 18

Step 2:
The number 18 fits into 66 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 54 from 66 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 18

Advancing to step 3:
18 can be fit into 123 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 108 from 123 to get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 18

Moving on to step 4:
18 goes into 154 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 368.0
The remainder is 10 after subtracting 144 from 154.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 18

On to step 5:
If we divide 101 by 18, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 3685.0
Subtracting 90 from 101 leaves us with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 18

Going ahead to step 6:
18 can be fit into 110 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 36856.0
If we take 108 away from 110, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 18

Going ahead to step 7:
25 divided by 18 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 368561.0
If we subtract 18 from 25, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 18

Step 8:
When dividing 76 by 18, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 3685614.0
If we subtract 72 from 76, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3685614.2
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3685614.22
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 3685614.22 with a remainder of 0.004.
