We divide 365568 by 87
The aim is to understand the frequency of 87 in 365568.

On to step 1:
87 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 87

Step 2:
87 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 87

Moving on to step 3:
365 divided by 87 is 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 348 from 365, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 87

Let's proceed to step 4:
If we divide 175 by 87, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 174 from 175 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 87

Let's proceed to step 5:
If we divide 16 by 87, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 420.0
Subtract 0 from 16 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 87

On to step 6:
The number 87 fits into 168 1 times, leaving a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 4201.0
If we subtract 87 from 168, we 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.

Let's proceed 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: 4201.9
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.

Let's proceed to step 8:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 4201.93
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.

On to step 9:
90 divided by 87 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4201.931
Subtracting 87 from 90 leaves us 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.

Advancing to step 10:
If we divide 30 by 87, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4201.931
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.

On to step 11:
The number 87 fits into 300 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 4201.93103
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
When dividing 390 by 87, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4201.931034
Deduct 348 from 390 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4201.9310344
If we take 348 away from 420, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 4201.9310344 and a remainder of 7.2e-07.
