We look at the division of 81564947 by 30 
We want to divide 81564947 by 30.

Advancing to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 30

Advancing to step 2:
If we divide 81 by 30, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 60 away from 81, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 30

Step 3:
If we divide 215 by 30, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 5 after subtracting 210 from 215.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 30

Advancing to step 4:
30 goes into 56 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 271.0
Deduct 30 from 56 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 30

Let's proceed to step 5:
When dividing 264 by 30, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 2718.0
The remainder is 24 after subtracting 240 from 264.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 30

Advancing to step 6:
30 can be fit into 249 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 27188.0
Deduct 240 from 249 and we're left with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 30

Let's proceed to step 7:
If we divide 94 by 30, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 271883.0
Subtract 90 from 94 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 30

Moving on to step 8:
If we divide 47 by 30, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 2718831.0
Subtracting 30 from 47 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
If we divide 170 by 30, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2718831.5
If we take 150 away from 170, we end up 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.

Going ahead to step 10:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 2718831.56
Subtracting 180 from 200 leaves us 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.

Step 11:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 2718831.566
Subtract 180 from 200 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.

The final result is 2718831.566 with a remainder of 0.002.
