Let's divide 87904326 by 871
The aim is to understand the frequency of 871 in 87904326.

Step 1:
If we divide 8 by 871, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 871

Moving on to step 2:
The number 871 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 871

Step 3:
The number 871 fits into 879 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 871 from 879.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 871

Let's proceed to step 4:
The number 871 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 871

Advancing to step 5:
If we divide 804 by 871, we get 0 and a remainder of 804.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 804 to get 804.
Grab the next digit (3) from the dividend, add it to 804, then carry on: 8043 / 871

Moving on to step 6:
871 goes into 8043 9 times with a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 1009.0
Deduct 7839 from 8043 and we're left with 204.
Bring next digit (2) of the dividend behind the 204 and repeat the process: 2042 / 871

Moving on to step 7:
If we divide 2042 by 871, we get 2 and a remainder of 300.
Put 2 as the next digit of the answer. 
Result so far: 10092.0
Subtract 1742 from 2042 to get 300.
Take the next digit (6) from the dividend and append it to 300, then repeat: 3006 / 871

Moving on to step 8:
871 goes into 3006 3 times with a remainder of 393.
The next digit of our result is 3. 
Result so far: 100923.0
The remainder is 393 after subtracting 2613 from 3006.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 9:
871 can be fit into 3930 4 times, resulting in a remainder of 446.
Record the quotient 4 as the next digit in the result. 
Result so far: 100923.4
Subtracting 3484 from 3930 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 10:
871 can be fit into 4460 5 times, resulting in a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 100923.45
Deduct 4355 from 4460 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 11:
871 goes into 1050 1 times with a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 100923.451
The remainder is 179 after subtracting 871 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 12:
871 can be fit into 1790 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 100923.4512
Deduct 1742 from 1790 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
The number 871 fits into 480 0 times, leaving a remainder of 480.
The next digit of our result is 0. 
Result so far: 100923.4512
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
871 goes into 4800 5 times with a remainder of 445.
The next digit of our result is 5. 
Result so far: 100923.451205
Deduct 4355 from 4800 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 15:
4450 divided by 871 is 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 100923.4512055
Subtracting 4355 from 4450 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Our division results in 100923.4512055 with a remaining 9.5e-07.
