Let's divide 78985764 by 30
We want to figure out the number of times 78985764 can be divided by 30.

On to step 1:
7 divided by 30 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 30

Going ahead to step 2:
The number 30 fits into 78 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 60 from 78 and we're left with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 30

Step 3:
The number 30 fits into 189 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 180 from 189 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 30

Moving on to step 4:
When dividing 98 by 30, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 263.0
Subtract 90 from 98 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 30

On to step 5:
30 goes into 85 2 times with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2632.0
The remainder is 25 after subtracting 60 from 85.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 30

On to step 6:
257 divided by 30 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 26328.0
Deduct 240 from 257 and we're left with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 30

Advancing to step 7:
If we divide 176 by 30, we get 5 and a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 263285.0
If we take 150 away from 176, we end up with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 30

Moving on to step 8:
264 divided by 30 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 2632858.0
If we take 240 away from 264, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
The number 30 fits into 240 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 2632858.8
Deduct 240 from 240 and we're left 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.

Moving on to step 10:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2632858.8
Subtracting 0 from 0 leaves us 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:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2632858.8
If we subtract 0 from 0, we 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.

Our division results in 2632858.8 with a remaining 0.0.
