We look at the division of 979961 by 87 
The aim is to understand the frequency of 87 in 979961.

Let's proceed to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 87

Step 2:
97 divided by 87 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 10 after subtracting 87 from 97.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 87

Going ahead to step 3:
87 goes into 109 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 87 from 109, we get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 87

Going ahead to step 4:
87 goes into 229 2 times with a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 174 from 229 and we're left with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 87

Moving on to step 5:
The number 87 fits into 556 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
If we subtract 522 from 556, we get 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 87

Let's proceed to step 6:
If we divide 341 by 87, we get 3 and a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 11263.0
Deduct 261 from 341 and we're left 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.

Step 7:
The number 87 fits into 800 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 11263.9
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
170 divided by 87 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 11263.91
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.

Step 9:
If we divide 830 by 87, we get 9 and a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 11263.919
If we take 783 away from 830, we end up 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 10:
87 goes into 470 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 11263.9195
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.

Step 11:
When dividing 350 by 87, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 11263.91954
The remainder is 2 after subtracting 348 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
When dividing 20 by 87, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11263.91954
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 87 fits into 200 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 11263.9195402
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
87 can be fit into 260 2 times, resulting in a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 11263.91954022
The remainder is 86 after subtracting 174 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 11263.91954022 with a balance of 8.6e-08.
