We're dividing 977309 by 87 
The aim is to understand the frequency of 87 in 977309.

Moving on to step 1:
87 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 87

On to step 2:
97 divided by 87 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 87 from 97, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 87

Advancing to step 3:
87 can be fit into 107 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 87 from 107 leaves us with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 87

Advancing to step 4:
The number 87 fits into 203 2 times, leaving a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 174 from 203 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 87

On to step 5:
87 goes into 290 3 times with a remainder of 29.
The next digit of our result is 3. 
Result so far: 1123.0
If we take 261 away from 290, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 87

Moving on to step 6:
87 goes into 299 3 times with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 11233.0
Subtract 261 from 299 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.

Step 7:
When dividing 380 by 87, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 11233.4
The remainder is 32 after subtracting 348 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
87 can be fit into 320 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 11233.43
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
87 can be fit into 590 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 11233.436
Deduct 522 from 590 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
680 divided by 87 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 11233.4367
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
87 goes into 710 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 11233.43678
Subtract 696 from 710 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
87 goes into 140 1 times with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 11233.436781
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
530 divided by 87 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 11233.4367816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
When dividing 80 by 87, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 11233.4367816
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 11233.4367816, with a leftover of 8e-08.
