We look at the division of 182525 by 77 
The aim is to understand the frequency of 77 in 182525.

Going ahead to step 1:
1 divided by 77 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 77

Moving on to step 2:
77 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 77

Advancing to step 3:
When dividing 182 by 77, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 154 away from 182, we end up with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 77

Let's proceed to step 4:
When dividing 285 by 77, we get 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 231 from 285 leaves us with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 77

Moving on to step 5:
The number 77 fits into 542 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 237.0
If we take 539 away from 542, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 77

Going ahead to step 6:
35 divided by 77 is 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 2370.0
Deduct 0 from 35 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
If we divide 350 by 77, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 2370.4
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
If we divide 420 by 77, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2370.45
If we subtract 385 from 420, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
The number 77 fits into 350 4 times, leaving a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 2370.454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 2370.4545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
If we divide 350 by 77, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 2370.45454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2370.454545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
If we divide 350 by 77, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 2370.4545454
Subtract 308 from 350 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
420 divided by 77 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 2370.45454545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 2370.45454545, and the remainder is 3.5e-08.
