We divide 78533438 by 30
We want to figure out the number of times 78533438 can be divided by 30.

Moving on to step 1:
7 divided by 30 is 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 30

Advancing to step 2:
30 can be fit into 78 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 60 away from 78, we end up with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 30

Let's proceed to step 3:
30 goes into 185 6 times with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 180 from 185 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 30

Let's proceed to step 4:
53 divided by 30 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Subtracting 30 from 53 leaves us with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 30

Moving on to step 5:
30 goes into 233 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2617.0
If we take 210 away from 233, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 30

Let's proceed to step 6:
30 goes into 234 7 times with a remainder of 24.
The next digit of our result is 7. 
Result so far: 26177.0
Subtracting 210 from 234 leaves us with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 30

Going ahead to step 7:
243 divided by 30 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 261778.0
Subtracting 240 from 243 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 30

Moving on to step 8:
30 can be fit into 38 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 2617781.0
The remainder is 8 after subtracting 30 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 30 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 2617781.2
The remainder is 20 after subtracting 60 from 80.
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:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 2617781.26
Deduct 180 from 200 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.

Advancing to step 11:
200 divided by 30 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 2617781.266
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.

The quotient of the division is 2617781.266, and the remainder is 0.002.
