73413 divided by 87 
The aim is to understand the frequency of 87 in 73413.

On to step 1:
87 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 87

Let's proceed to step 2:
73 divided by 87 is 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 87

Let's proceed to step 3:
87 can be fit into 734 8 times, resulting in a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 696 away from 734, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 87

Step 4:
87 goes into 381 4 times with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 348 from 381, we get 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 87

Going ahead to step 5:
333 divided by 87 is 3 with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 843.0
If we subtract 261 from 333, 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.

On to step 6:
720 divided by 87 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 843.8
The remainder is 24 after subtracting 696 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
If we divide 240 by 87, we get 2 and a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 843.82
If we subtract 174 from 240, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
87 goes into 660 7 times with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 843.827
Subtract 609 from 660 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
When dividing 510 by 87, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 843.8275
Subtract 435 from 510 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
750 divided by 87 is 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 843.82758
If we subtract 696 from 750, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
87 goes into 540 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 843.827586
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
If we divide 180 by 87, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 843.8275862
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
If we divide 60 by 87, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 843.8275862
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 843.8275862, with a leftover of 6e-08.
