We look at the division of 479931 by 87 
The aim is to understand the frequency of 87 in 479931.

Moving on to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 87

On to step 2:
87 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 87

Let's proceed to step 3:
479 divided by 87 is 5 with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 435 from 479 and we're left with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 87

On to step 4:
87 goes into 449 5 times with a remainder of 14.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 435 from 449 and we're left with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 87

Moving on to step 5:
143 divided by 87 is 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 551.0
Subtracting 87 from 143 leaves us with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 87

Advancing to step 6:
When dividing 561 by 87, we get 6 with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 5516.0
Deduct 522 from 561 and we're left with 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 7:
When dividing 390 by 87, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 5516.4
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.

Step 8:
When dividing 420 by 87, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 5516.44
Deduct 348 from 420 and we're left 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.

In conclusion, the division gives 5516.44 with a balance of 0.072.
