We divide 9042308 by 871
The aim is to understand the frequency of 871 in 9042308.

Step 1:
When dividing 9 by 871, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 871

Advancing to step 2:
90 divided by 871 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 871

Moving on to step 3:
871 goes into 904 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 871 away from 904, we end up with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 871

Going ahead to step 4:
When dividing 332 by 871, we get 0 with a remainder of 332.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 332 leaves us with 332.
Grab the next digit (3) from the dividend, add it to 332, then carry on: 3323 / 871

Advancing to step 5:
871 can be fit into 3323 3 times, resulting in a remainder of 710.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
The remainder is 710 after subtracting 2613 from 3323.
Take the next digit (0) from the dividend and append it to 710, then repeat: 7100 / 871

Moving on to step 6:
If we divide 7100 by 871, we get 8 and a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 1038.0
If we subtract 6968 from 7100, we get 132.
Append the next digit (8) from the dividend to 132 and continue with: 1328 / 871

Going ahead to step 7:
When dividing 1328 by 871, we get 1 with a remainder of 457.
Put 1 as the next digit of the answer. 
Result so far: 10381.0
If we take 871 away from 1328, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 8:
When dividing 4570 by 871, we get 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 10381.5
Subtract 4355 from 4570 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
If we divide 2150 by 871, we get 2 and a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 10381.52
Deduct 1742 from 2150 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 10:
The number 871 fits into 4080 4 times, leaving a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 10381.524
The remainder is 596 after subtracting 3484 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 11:
If we divide 5960 by 871, we get 6 and a remainder of 734.
Write down 6 as next digit of the result. 
Result so far: 10381.5246
Deduct 5226 from 5960 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Moving on to step 12:
7340 divided by 871 is 8 with a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 10381.52468
If we subtract 6968 from 7340, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 13:
871 can be fit into 3720 4 times, resulting in a remainder of 236.
The next digit of our result is 4. 
Result so far: 10381.524684
The remainder is 236 after subtracting 3484 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 14:
871 goes into 2360 2 times with a remainder of 618.
Record the quotient 2 as the next digit in the result. 
Result so far: 10381.5246842
If we take 1742 away from 2360, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 15:
871 can be fit into 6180 7 times, resulting in a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 10381.52468427
If we subtract 6097 from 6180, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 10381.52468427 and a remainder of 8.3e-08.
