We're dividing 71866101 by 30 
We want to figure out the number of times 71866101 can be divided by 30.

Let's proceed to step 1:
When dividing 7 by 30, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 30

Going ahead to step 2:
If we divide 71 by 30, we get 2 and a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 60 away from 71, we end up with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 30

On to step 3:
When dividing 118 by 30, we get 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 28 after subtracting 90 from 118.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 30

On to step 4:
30 goes into 286 9 times with a remainder of 16.
The next digit of our result is 9. 
Result so far: 239.0
Deduct 270 from 286 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 30

Let's proceed to step 5:
The number 30 fits into 166 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 2395.0
Subtracting 150 from 166 leaves us with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 30

Advancing to step 6:
The number 30 fits into 161 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 23955.0
If we take 150 away from 161, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 30

On to step 7:
If we divide 110 by 30, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 239553.0
The remainder is 20 after subtracting 90 from 110.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 30

Step 8:
The number 30 fits into 201 6 times, leaving a remainder of 21.
The next digit of our result is 6. 
Result so far: 2395536.0
If we subtract 180 from 201, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
30 can be fit into 210 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 2395536.7
Subtract 210 from 210 to get 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 10:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2395536.7
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.

Step 11:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2395536.7
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.

The quotient of the division is 2395536.7, and the remainder is 0.0.
