We're dividing 233546 by 87 
The aim is to understand the frequency of 87 in 233546.

Going ahead to step 1:
When dividing 2 by 87, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 87

Advancing to step 2:
If we divide 23 by 87, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 87

Advancing to step 3:
When dividing 233 by 87, we get 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 174 away from 233, we end up with 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 87

Let's proceed to step 4:
If we divide 595 by 87, we get 6 and a remainder of 73.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 522 from 595 to get 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 87

On to step 5:
734 divided by 87 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 268.0
Subtract 696 from 734 to get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 87

Going ahead to step 6:
When dividing 386 by 87, we get 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 2684.0
Subtracting 348 from 386 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
When dividing 380 by 87, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2684.4
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
87 can be fit into 320 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 2684.43
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 87, we get 6 and a remainder of 68.
The next digit of our result is 6. 
Result so far: 2684.436
If we take 522 away from 590, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
The number 87 fits into 680 7 times, leaving a remainder of 71.
The next digit of our result is 7. 
Result so far: 2684.4367
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 11:
710 divided by 87 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 2684.43678
Subtract 696 from 710 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
87 goes into 140 1 times with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 2684.436781
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
If we divide 530 by 87, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 2684.4367816
Subtracting 522 from 530 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
If we divide 80 by 87, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 2684.4367816
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 2684.4367816 with a remainder of 8e-08.
