Let's divide 61902 by 18
We're looking to find how many times 18 goes into 61902.

Step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 18

Moving on to step 2:
The number 18 fits into 61 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 54 away from 61, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 18

Advancing to step 3:
The number 18 fits into 79 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 72 from 79 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 18

On to step 4:
70 divided by 18 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 343.0
Subtract 54 from 70 to get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 18

Let's proceed to step 5:
The number 18 fits into 162 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3439.0
If we take 162 away from 162, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
18 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3439.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3439.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3439.0 and a remainder of 0.0.
