We look at the division of 337612 by 87 
The aim is to understand the frequency of 87 in 337612.

Going ahead to step 1:
3 divided by 87 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 87

Advancing to step 2:
33 divided by 87 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 87

Moving on to step 3:
87 goes into 337 3 times with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 261 from 337 leaves us with 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 87

Step 4:
87 can be fit into 766 8 times, resulting in a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 696 from 766, we get 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 87

Moving on to step 5:
The number 87 fits into 701 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 388.0
The remainder is 5 after subtracting 696 from 701.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 87

Step 6:
The number 87 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 3880.0
Deduct 0 from 52 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
87 goes into 520 5 times with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 3880.5
If we take 435 away from 520, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 8:
When dividing 850 by 87, we get 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 3880.59
Subtract 783 from 850 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
The number 87 fits into 670 7 times, leaving a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 3880.597
If we take 609 away from 670, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
When dividing 610 by 87, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 3880.5977
The remainder is 1 after subtracting 609 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 3880.5977 with a balance of 1e-05.
