We're dividing 587515 by 77 
The aim is to understand the frequency of 77 in 587515.

Moving on to step 1:
77 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 77

Let's proceed to step 2:
If we divide 58 by 77, we get 0 and a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 77

Going ahead to step 3:
77 goes into 587 7 times with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 539 from 587 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 77

Step 4:
When dividing 485 by 77, we get 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 462 from 485 to get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 77

Advancing to step 5:
The number 77 fits into 231 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 763.0
Subtract 231 from 231 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 77

Advancing to step 6:
The number 77 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 7630.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 77, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 7630.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
If we divide 500 by 77, we get 6 and a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 7630.06
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
77 can be fit into 380 4 times, resulting in a remainder of 72.
The next digit of our result is 4. 
Result so far: 7630.064
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
The number 77 fits into 720 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 7630.0649
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 77, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 7630.06493
If we take 231 away from 270, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
390 divided by 77 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7630.064935
The remainder is 5 after subtracting 385 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
77 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7630.064935
If we subtract 0 from 50, we 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.

Let's proceed to step 14:
If we divide 500 by 77, we get 6 and a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 7630.06493506
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 7630.06493506 with a remaining 3.8e-08.
