We're dividing 94778 by 87 
The aim is to understand the frequency of 87 in 94778.

Advancing to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 87

On to step 2:
87 goes into 94 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 7 after subtracting 87 from 94.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 87

Going ahead to step 3:
The number 87 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 77, we get 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 87

Let's proceed to step 4:
If we divide 777 by 87, we get 8 and a remainder of 81.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 696 from 777, we get 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 87

Step 5:
When dividing 818 by 87, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 1089.0
If we take 783 away from 818, we end up with 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 6:
87 goes into 350 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1089.4
Subtracting 348 from 350 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 87, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1089.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 87 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 1089.402
Deduct 174 from 200 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
87 goes into 260 2 times with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 1089.4022
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 1089.4022 with a remainder of 0.00086.
