We look at the division of 6683 by 87 
The aim is to understand the frequency of 87 in 6683.

On to step 1:
87 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 87

Moving on to step 2:
When dividing 66 by 87, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 87

Let's proceed to step 3:
If we divide 668 by 87, we get 7 and a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 59 after subtracting 609 from 668.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 87

Step 4:
The number 87 fits into 593 6 times, leaving a remainder of 71.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 522 from 593 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 5:
If we divide 710 by 87, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 76.8
Subtracting 696 from 710 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 6:
If we divide 140 by 87, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 76.81
Subtracting 87 from 140 leaves us 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 7:
87 goes into 530 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 76.816
Subtract 522 from 530 to get 8.
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.
Write down 0 as next digit of the result. 
Result so far: 76.816
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
800 divided by 87 is 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 76.81609
Subtract 783 from 800 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
If we divide 170 by 87, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 76.816091
Subtract 87 from 170 to get 83.
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:
87 goes into 830 9 times with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 76.8160919
If we subtract 783 from 830, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
87 can be fit into 470 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 76.81609195
Subtract 435 from 470 to 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.

The final result is 76.81609195 with a remainder of 3.5e-08.
