We're dividing 887742 by 87 
The aim is to understand the frequency of 87 in 887742.

Let's proceed to step 1:
The number 87 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 87

Going ahead to step 2:
When dividing 88 by 87, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 87 away from 88, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 87

Step 3:
17 divided by 87 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 17, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 87

Advancing to step 4:
The number 87 fits into 177 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 102.0
If we take 174 away from 177, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 87

Step 5:
When dividing 34 by 87, we get 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 1020.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 87

Moving on to step 6:
If we divide 342 by 87, we get 3 and a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 10203.0
Subtract 261 from 342 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
87 goes into 810 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 10203.9
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
87 goes into 270 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 10203.93
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 87, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 10203.931
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
87 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10203.931
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
87 can be fit into 300 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 10203.93103
Deduct 261 from 300 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 10203.931034
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
87 can be fit into 420 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 10203.9310344
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 10203.9310344, and the remainder is 7.2e-07.
