We're dividing 368265 by 87 
The aim is to understand the frequency of 87 in 368265.

Advancing to step 1:
87 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 87

Going ahead to step 2:
The number 87 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 87

On to step 3:
When dividing 368 by 87, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 348 from 368, we get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 87

Advancing to step 4:
When dividing 202 by 87, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 174 from 202 leaves us with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 87

Let's proceed to step 5:
The number 87 fits into 286 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 423.0
Subtract 261 from 286 to get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 87

Going ahead to step 6:
255 divided by 87 is 2 with a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 4232.0
Subtract 174 from 255 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.

Advancing to step 7:
87 can be fit into 810 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 4232.9
Deduct 783 from 810 and we're left 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.

Moving on to step 8:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 4232.93
If we take 261 away from 270, we end up 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.

Moving on to step 9:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4232.931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
87 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4232.931
Deduct 0 from 30 and we're left 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.

Let's proceed to step 11:
When dividing 300 by 87, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 4232.93103
If we take 261 away from 300, we end up 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 goes into 390 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4232.931034
If we subtract 348 from 390, we 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.

Moving on to step 13:
87 goes into 420 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 4232.9310344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 4232.9310344 with a remaining 7.2e-07.
