766175 divided by 87 
The aim is to understand the frequency of 87 in 766175.

Let's proceed to step 1:
87 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 87

Step 2:
If we divide 76 by 87, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 87

Going ahead to step 3:
When dividing 766 by 87, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 70 after subtracting 696 from 766.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 87

Step 4:
701 divided by 87 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 88.0
If we subtract 696 from 701, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 87

Advancing to step 5:
When dividing 57 by 87, we get 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 880.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 87

Going ahead to step 6:
If we divide 575 by 87, we get 6 and a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 8806.0
If we subtract 522 from 575, we get 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 7:
The number 87 fits into 530 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 8806.6
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.

Let's proceed to step 8:
80 divided by 87 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 8806.6
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.

Advancing to step 9:
When dividing 800 by 87, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 8806.609
Subtracting 783 from 800 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
When dividing 170 by 87, we get 1 with a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 8806.6091
The remainder is 83 after subtracting 87 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 11:
The number 87 fits into 830 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 8806.60919
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 12:
The number 87 fits into 470 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8806.609195
If we subtract 435 from 470, 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.

Moving on to step 13:
87 goes into 350 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 8806.6091954
Subtract 348 from 350 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:
20 divided by 87 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8806.6091954
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.

After the division, we end up with 8806.6091954 and a remainder of 2e-08.
