We look at the division of 77086072 by 773 
The aim is to understand the frequency of 773 in 77086072.

Advancing to step 1:
7 divided by 773 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 773

Let's proceed to step 2:
When dividing 77 by 773, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 773

Going ahead to step 3:
If we divide 770 by 773, we get 0 and a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 770 and we're left with 770.
Append the next digit (8) from the dividend to 770 and continue with: 7708 / 773

Step 4:
7708 divided by 773 is 9 with a remainder of 751.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 6957 from 7708 to get 751.
Grab the next digit (6) from the dividend, add it to 751, then carry on: 7516 / 773

Moving on to step 5:
773 goes into 7516 9 times with a remainder of 559.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 6957 from 7516 leaves us with 559.
Grab the next digit (0) from the dividend, add it to 559, then carry on: 5590 / 773

Step 6:
773 goes into 5590 7 times with a remainder of 179.
Write down 7 as next digit of the result. 
Result so far: 997.0
Subtract 5411 from 5590 to get 179.
Append the next digit (7) from the dividend to 179 and continue with: 1797 / 773

On to step 7:
If we divide 1797 by 773, we get 2 and a remainder of 251.
The next digit of our result is 2. 
Result so far: 9972.0
If we take 1546 away from 1797, we end up with 251.
Take the next digit (2) from the dividend and append it to 251, then repeat: 2512 / 773

Advancing to step 8:
773 goes into 2512 3 times with a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 99723.0
The remainder is 193 after subtracting 2319 from 2512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
If we divide 1930 by 773, we get 2 and a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 99723.2
The remainder is 384 after subtracting 1546 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
773 can be fit into 3840 4 times, resulting in a remainder of 748.
Write down 4 as next digit of the result. 
Result so far: 99723.24
The remainder is 748 after subtracting 3092 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Let's proceed to step 11:
If we divide 7480 by 773, we get 9 and a remainder of 523.
Use 9 as the next digit of our solution. 
Result so far: 99723.249
Subtracting 6957 from 7480 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 12:
5230 divided by 773 is 6 with a remainder of 592.
The next digit of our result is 6. 
Result so far: 99723.2496
The remainder is 592 after subtracting 4638 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 13:
773 goes into 5920 7 times with a remainder of 509.
Put 7 as the next digit of the answer. 
Result so far: 99723.24967
If we subtract 5411 from 5920, we get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Step 14:
The number 773 fits into 5090 6 times, leaving a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 99723.249676
Subtracting 4638 from 5090 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 15:
When dividing 4520 by 773, we get 5 with a remainder of 655.
The number 5 becomes the next digit in our result. 
Result so far: 99723.2496765
Subtract 3865 from 4520 to get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Advancing to step 16:
6550 divided by 773 is 8 with a remainder of 366.
The number 8 becomes the next digit in our result. 
Result so far: 99723.24967658
If we take 6184 away from 6550, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The final outcome is 99723.24967658, with a leftover of 3.66e-07.
