79511640 ÷ 30 
Let's see how many times 30 fits into 79511640.

Moving on to step 1:
30 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 30

Let's proceed to step 2:
30 goes into 79 2 times with a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 60 from 79 leaves us with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 30

Step 3:
The number 30 fits into 195 6 times, leaving a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 180 from 195, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 30

Let's proceed to step 4:
If we divide 151 by 30, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Deduct 150 from 151 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 30

Let's proceed to step 5:
When dividing 11 by 30, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 2650.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 30

Moving on to step 6:
When dividing 116 by 30, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 26503.0
If we take 90 away from 116, we end up with 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 30

Going ahead to step 7:
30 can be fit into 264 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 265038.0
Deduct 240 from 264 and we're left with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 30

Advancing to step 8:
240 divided by 30 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 2650388.0
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.

Advancing to step 9:
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: 2650388.0
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.

Moving on to step 10:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2650388.0
The remainder is 0 after subtracting 0 from 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 final result is 2650388.0 with a remainder of 0.0.
