Let's divide 77170274 by 30
We're looking to find how many times 30 goes into 77170274.

On to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 30

Step 2:
When dividing 77 by 30, we get 2 with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 60 from 77 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 30

On to step 3:
30 can be fit into 171 5 times, resulting in a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 150 from 171, we get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 30

On to step 4:
30 can be fit into 217 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
If we subtract 210 from 217, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 30

Going ahead to step 5:
30 can be fit into 70 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2572.0
Deduct 60 from 70 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 30

Going ahead to step 6:
30 can be fit into 102 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 25723.0
Subtracting 90 from 102 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 30

Advancing to step 7:
If we divide 127 by 30, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 257234.0
If we take 120 away from 127, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 30

Moving on to step 8:
30 goes into 74 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2572342.0
If we take 60 away from 74, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
30 goes into 140 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 2572342.4
The remainder is 20 after subtracting 120 from 140.
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:
30 goes into 200 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 2572342.46
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.

Let's proceed to step 11:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 2572342.466
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.

The final result is 2572342.466 with a remainder of 0.002.
