Let's divide 76018531 by 770
The aim is to understand the frequency of 770 in 76018531.

Moving on to step 1:
The number 770 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 770

Advancing to step 2:
770 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 770

Moving on to step 3:
770 can be fit into 760 0 times, resulting in a remainder of 760.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 760 leaves us with 760.
Take the next digit (1) from the dividend and append it to 760, then repeat: 7601 / 770

Step 4:
When dividing 7601 by 770, we get 9 with a remainder of 671.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 671 after subtracting 6930 from 7601.
Include the next digit (8) from the dividend after 671, then repeat: 6718 / 770

Moving on to step 5:
The number 770 fits into 6718 8 times, leaving a remainder of 558.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Deduct 6160 from 6718 and we're left with 558.
Append the next digit (5) from the dividend to 558 and continue with: 5585 / 770

Moving on to step 6:
770 can be fit into 5585 7 times, resulting in a remainder of 195.
The number 7 becomes the next digit in our result. 
Result so far: 987.0
The remainder is 195 after subtracting 5390 from 5585.
Append the next digit (3) from the dividend to 195 and continue with: 1953 / 770

Advancing to step 7:
When dividing 1953 by 770, we get 2 with a remainder of 413.
Use 2 as the next digit of our solution. 
Result so far: 9872.0
Deduct 1540 from 1953 and we're left with 413.
Include the next digit (1) from the dividend after 413, then repeat: 4131 / 770

Moving on to step 8:
If we divide 4131 by 770, we get 5 and a remainder of 281.
Write down 5 as next digit of the result. 
Result so far: 98725.0
Deduct 3850 from 4131 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 9:
The number 770 fits into 2810 3 times, leaving a remainder of 500.
The next digit of our result is 3. 
Result so far: 98725.3
If we take 2310 away from 2810, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
770 goes into 5000 6 times with a remainder of 380.
Write down 6 as next digit of the result. 
Result so far: 98725.36
If we subtract 4620 from 5000, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
770 goes into 3800 4 times with a remainder of 720.
Record the quotient 4 as the next digit in the result. 
Result so far: 98725.364
If we take 3080 away from 3800, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 12:
The number 770 fits into 7200 9 times, leaving a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 98725.3649
Subtracting 6930 from 7200 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 13:
2700 divided by 770 is 3 with a remainder of 390.
The next digit of our result is 3. 
Result so far: 98725.36493
Subtracting 2310 from 2700 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
770 can be fit into 3900 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 98725.364935
Subtract 3850 from 3900 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
When dividing 500 by 770, we get 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 98725.364935
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 16:
If we divide 5000 by 770, we get 6 and a remainder of 380.
Put 6 as the next digit of the answer. 
Result so far: 98725.36493506
The remainder is 380 after subtracting 4620 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 98725.36493506, with a leftover of 3.8e-07.
