We look at the division of 65408618 by 210 
Let's see how many times 210 fits into 65408618.

On to step 1:
210 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 210

Going ahead to step 2:
When dividing 65 by 210, we get 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 210

Let's proceed to step 3:
If we divide 654 by 210, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 630 from 654 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 210

On to step 4:
210 goes into 240 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 210 from 240 to get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 210

Advancing to step 5:
308 divided by 210 is 1 with a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 311.0
The remainder is 98 after subtracting 210 from 308.
Fetch the next digit (6) from the dividend, attach it to 98 and continue: 986 / 210

Advancing to step 6:
210 goes into 986 4 times with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 3114.0
Subtracting 840 from 986 leaves us with 146.
Bring next digit (1) of the dividend behind the 146 and repeat the process: 1461 / 210

Step 7:
210 goes into 1461 6 times with a remainder of 201.
Put 6 as the next digit of the answer. 
Result so far: 31146.0
If we subtract 1260 from 1461, we get 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 210

Step 8:
210 goes into 2018 9 times with a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 311469.0
The remainder is 128 after subtracting 1890 from 2018.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 9:
The number 210 fits into 1280 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 311469.6
Subtract 1260 from 1280 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
210 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 311469.6
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
210 goes into 2000 9 times with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 311469.609
If we subtract 1890 from 2000, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
210 goes into 1100 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 311469.6095
Subtract 1050 from 1100 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
If we divide 500 by 210, we get 2 and a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 311469.60952
The remainder is 80 after subtracting 420 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
When dividing 800 by 210, we get 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 311469.609523
Subtract 630 from 800 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
When dividing 1700 by 210, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 311469.6095238
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
When dividing 200 by 210, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 311469.6095238
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 311469.6095238 and a remainder of 2e-07.
