We're dividing 187526 by 77 
The aim is to understand the frequency of 77 in 187526.

Moving on to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 77

Moving on to step 2:
77 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 77

Going ahead to step 3:
When dividing 187 by 77, we get 2 with a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 154 from 187, we get 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 77

On to step 4:
The number 77 fits into 335 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 308 from 335 and we're left with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 77

Let's proceed to step 5:
272 divided by 77 is 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
If we subtract 231 from 272, we get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 77

On to step 6:
The number 77 fits into 416 5 times, leaving a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 2435.0
Deduct 385 from 416 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 77, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2435.4
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 77, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2435.4
If we take 0 away from 20, we end up 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.

Step 9:
The number 77 fits into 200 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 2435.402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 77 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 2435.4025
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
The number 77 fits into 750 9 times, leaving a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 2435.40259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
77 goes into 570 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 2435.402597
If we subtract 539 from 570, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 2435.4025974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
When dividing 20 by 77, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2435.4025974
Deduct 0 from 20 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.

Our division results in 2435.4025974 with a remaining 2e-08.
