Let's divide 11927501 by 871
The aim is to understand the frequency of 871 in 11927501.

Step 1:
If we divide 1 by 871, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 871

Moving on to step 2:
871 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 871

Going ahead to step 3:
871 goes into 119 0 times with a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 119 and we're left with 119.
Append the next digit (2) from the dividend to 119 and continue with: 1192 / 871

On to step 4:
The number 871 fits into 1192 1 times, leaving a remainder of 321.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 871 from 1192 to get 321.
Take the next digit (7) from the dividend and append it to 321, then repeat: 3217 / 871

On to step 5:
When dividing 3217 by 871, we get 3 with a remainder of 604.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 2613 away from 3217, we end up with 604.
Include the next digit (5) from the dividend after 604, then repeat: 6045 / 871

Going ahead to step 6:
871 goes into 6045 6 times with a remainder of 819.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 819 after subtracting 5226 from 6045.
Fetch the next digit (0) from the dividend, attach it to 819 and continue: 8190 / 871

Moving on to step 7:
8190 divided by 871 is 9 with a remainder of 351.
Record the quotient 9 as the next digit in the result. 
Result so far: 1369.0
If we take 7839 away from 8190, we end up with 351.
Bring next digit (1) of the dividend behind the 351 and repeat the process: 3511 / 871

Going ahead to step 8:
The number 871 fits into 3511 4 times, leaving a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 13694.0
Subtracting 3484 from 3511 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
871 goes into 270 0 times with a remainder of 270.
The next digit of our result is 0. 
Result so far: 13694.0
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
The number 871 fits into 2700 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 13694.03
The remainder is 87 after subtracting 2613 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 11:
871 goes into 870 0 times with a remainder of 870.
Write down 0 as next digit of the result. 
Result so far: 13694.03
Subtract 0 from 870 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Moving on to step 12:
871 goes into 8700 9 times with a remainder of 861.
The number 9 becomes the next digit in our result. 
Result so far: 13694.0309
Deduct 7839 from 8700 and we're left with 861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8610, and continue the process.

On to step 13:
The number 871 fits into 8610 9 times, leaving a remainder of 771.
Use 9 as the next digit of our solution. 
Result so far: 13694.03099
If we subtract 7839 from 8610, we get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

The quotient of the division is 13694.03099, and the remainder is 0.000771.
