Let's divide 81657878 by 30
We want to figure out the number of times 81657878 can be divided by 30.

Let's proceed to step 1:
30 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 30

Moving on to step 2:
30 goes into 81 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 60 from 81, we get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 30

On to step 3:
216 divided by 30 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 210 away from 216, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 30

On to step 4:
65 divided by 30 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 272.0
If we subtract 60 from 65, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 30

Advancing to step 5:
If we divide 57 by 30, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 2721.0
Subtracting 30 from 57 leaves us with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 30

Let's proceed to step 6:
When dividing 278 by 30, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 27219.0
If we take 270 away from 278, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 30

Step 7:
When dividing 87 by 30, we get 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 272192.0
If we subtract 60 from 87, we get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 30

Advancing to step 8:
When dividing 278 by 30, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 2721929.0
The remainder is 8 after subtracting 270 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
30 can be fit into 80 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2721929.2
Deduct 60 from 80 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.

On to step 10:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 2721929.26
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 30 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 2721929.266
If we take 180 away from 200, 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.

In conclusion, the division gives 2721929.266 with a balance of 0.002.
