616610 divided by 18 
We're looking to find how many times 18 goes into 616610.

Step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 18

Step 2:
18 goes into 61 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 54 away from 61, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 18

Going ahead to step 3:
The number 18 fits into 76 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 72 from 76 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 18

Moving on to step 4:
The number 18 fits into 46 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtract 36 from 46 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 18

Step 5:
101 divided by 18 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 3425.0
Subtracting 90 from 101 leaves us with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 18

Advancing to step 6:
When dividing 110 by 18, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 34256.0
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
18 can be fit into 20 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 34256.1
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 18, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 34256.11
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 34256.11 and a remainder of 0.002.
