We divide 77851169 by 30
The aim is to understand the frequency of 30 in 77851169.

On to step 1:
30 can be fit into 7 0 times, resulting in 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.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 30

On to step 2:
When dividing 77 by 30, we get 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 60 from 77 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 30

Going ahead to step 3:
The number 30 fits into 178 5 times, leaving a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 150 from 178 to get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 30

On to step 4:
When dividing 285 by 30, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 259.0
Subtracting 270 from 285 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 30

Going ahead to step 5:
The number 30 fits into 151 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 2595.0
If we subtract 150 from 151, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 30

Step 6:
When dividing 11 by 30, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 25950.0
Deduct 0 from 11 and we're left with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 30

Advancing to step 7:
30 goes into 116 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 259503.0
Subtract 90 from 116 to get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 30

Moving on to step 8:
When dividing 269 by 30, we get 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 2595038.0
Subtract 240 from 269 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
30 can be fit into 290 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 2595038.9
Deduct 270 from 290 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.

Moving on to step 10:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 2595038.96
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.

Going ahead to step 11:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 2595038.966
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.

After the division, we end up with 2595038.966 and a remainder of 0.002.
