100418 divided by 87 
The aim is to understand the frequency of 87 in 100418.

Let's proceed to step 1:
87 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 87

Advancing to step 2:
87 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 87

Going ahead to step 3:
When dividing 100 by 87, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 87 from 100 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 87

Advancing to step 4:
134 divided by 87 is 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 87 from 134 and we're left with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 87

Let's proceed to step 5:
87 goes into 471 5 times with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Deduct 435 from 471 and we're left with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 87

Going ahead to step 6:
368 divided by 87 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 1154.0
Subtracting 348 from 368 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 87 fits into 200 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1154.2
Subtract 174 from 200 to 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.

Moving on to step 8:
If we divide 260 by 87, we get 2 and a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 1154.22
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 1154.22 with a remaining 0.086.
