Let's divide 641710 by 18
We're looking to find how many times 18 goes into 641710.

Step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Let's proceed to step 2:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 54 from 64 to get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 18

On to step 3:
101 divided by 18 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 90 from 101 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 18

Going ahead to step 4:
The number 18 fits into 117 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 356.0
If we take 108 away from 117, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 18

Step 5:
The number 18 fits into 91 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 3565.0
Subtract 90 from 91 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 18

Step 6:
18 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 35650.0
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.

Moving on to step 7:
18 goes into 100 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 35650.5
The remainder is 10 after subtracting 90 from 100.
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 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 35650.55
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.

The final outcome is 35650.55, with a leftover of 0.01.
