We're dividing 256073 by 87 
The aim is to understand the frequency of 87 in 256073.

Advancing to step 1:
2 divided by 87 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 87

Moving on to step 2:
87 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 87

Advancing to step 3:
256 divided by 87 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 174 from 256 to get 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 87

Going ahead to step 4:
When dividing 820 by 87, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 783 from 820 leaves us with 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 87

Advancing to step 5:
87 goes into 377 4 times with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Subtracting 348 from 377 leaves us with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 87

On to step 6:
87 can be fit into 293 3 times, resulting in a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 2943.0
The remainder is 32 after subtracting 261 from 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
When dividing 320 by 87, we get 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 2943.3
Subtract 261 from 320 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 8:
87 goes into 590 6 times with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 2943.36
Subtracting 522 from 590 leaves us 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.

On to step 9:
680 divided by 87 is 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 2943.367
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.

Moving on to step 10:
87 goes into 710 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 2943.3678
If we subtract 696 from 710, we 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.

Advancing to step 11:
87 goes into 140 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 2943.36781
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.

Step 12:
If we divide 530 by 87, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 2943.367816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
When dividing 80 by 87, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 2943.367816
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
The number 87 fits into 800 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 2943.36781609
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 2943.36781609 with a remaining 1.7e-08.
