Let's divide 87575 by 71
The aim is to understand the frequency of 71 in 87575.

Moving on to step 1:
If we divide 8 by 71, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 71

Advancing to step 2:
87 divided by 71 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 71 away from 87, we end up with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 71

On to step 3:
71 goes into 165 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 142 from 165 to get 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 71

On to step 4:
If we divide 237 by 71, we get 3 and a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 213 from 237, we get 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 71

On to step 5:
71 can be fit into 245 3 times, resulting in a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 1233.0
The remainder is 32 after subtracting 213 from 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 6:
71 can be fit into 320 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1233.4
Deduct 284 from 320 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
If we divide 360 by 71, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1233.45
If we take 355 away from 360, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 71, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1233.45
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
71 goes into 500 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1233.4507
If we take 497 away from 500, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
When dividing 30 by 71, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1233.4507
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 71 fits into 300 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1233.450704
The remainder is 16 after subtracting 284 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
71 goes into 160 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1233.4507042
Deduct 142 from 160 and we're left 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.

Step 13:
71 can be fit into 180 2 times, resulting in a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 1233.45070422
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 1233.45070422 with a remaining 3.8e-08.
