We look at the division of 914578 by 87 
The aim is to understand the frequency of 87 in 914578.

Going ahead to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 87

On to step 2:
91 divided by 87 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 87 from 91 and we're left with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 87

Moving on to step 3:
87 can be fit into 44 0 times, resulting in a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 44 and we're left with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 87

Step 4:
87 can be fit into 445 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 435 from 445, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 87

Going ahead to step 5:
107 divided by 87 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
If we take 87 away from 107, we end up with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 87

Let's proceed to step 6:
87 goes into 208 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 10512.0
Subtract 174 from 208 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
340 divided by 87 is 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 10512.3
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 8:
87 goes into 790 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 10512.39
If we take 783 away from 790, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 87 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 10512.39
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
87 can be fit into 700 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 10512.3908
Subtract 696 from 700 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
87 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10512.3908
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 87, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 10512.390804
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
87 can be fit into 520 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 10512.3908045
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 14:
When dividing 850 by 87, we get 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 10512.39080459
The remainder is 67 after subtracting 783 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 10512.39080459 and a remainder of 6.7e-08.
