71585156 divided by 87 
The aim is to understand the frequency of 87 in 71585156.

Moving on to step 1:
7 divided by 87 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 87

Let's proceed to step 2:
87 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 87

Let's proceed to step 3:
If we divide 715 by 87, we get 8 and a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 19 after subtracting 696 from 715.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 87

On to step 4:
If we divide 198 by 87, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtracting 174 from 198 leaves us with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 87

On to step 5:
When dividing 245 by 87, we get 2 with a remainder of 71.
Record the quotient 2 as the next digit in the result. 
Result so far: 822.0
If we subtract 174 from 245, we get 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 87

Let's proceed to step 6:
711 divided by 87 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 8228.0
If we subtract 696 from 711, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 87

On to step 7:
87 can be fit into 155 1 times, resulting in a remainder of 68.
The next digit of our result is 1. 
Result so far: 82281.0
Subtracting 87 from 155 leaves us with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 87

On to step 8:
686 divided by 87 is 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 822817.0
The remainder is 77 after subtracting 609 from 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
87 goes into 770 8 times with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 822817.8
Deduct 696 from 770 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
87 goes into 740 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 822817.88
If we take 696 away from 740, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 822817.88 with a balance of 0.044.
