We look at the division of 28922920 by 871 
The aim is to understand the frequency of 871 in 28922920.

On to step 1:
871 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 871

Let's proceed to step 2:
When dividing 28 by 871, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 871

Step 3:
The number 871 fits into 289 0 times, leaving a remainder of 289.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 289, we end up with 289.
Grab the next digit (2) from the dividend, add it to 289, then carry on: 2892 / 871

Step 4:
871 can be fit into 2892 3 times, resulting in a remainder of 279.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2613 from 2892 and we're left with 279.
Include the next digit (2) from the dividend after 279, then repeat: 2792 / 871

Going ahead to step 5:
871 goes into 2792 3 times with a remainder of 179.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 179 after subtracting 2613 from 2792.
Bring next digit (9) of the dividend behind the 179 and repeat the process: 1799 / 871

Let's proceed to step 6:
When dividing 1799 by 871, we get 2 with a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 332.0
Subtracting 1742 from 1799 leaves us with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 871

Advancing to step 7:
The number 871 fits into 572 0 times, leaving a remainder of 572.
Put 0 as the next digit of the answer. 
Result so far: 3320.0
If we take 0 away from 572, we end up with 572.
Fetch the next digit (0) from the dividend, attach it to 572 and continue: 5720 / 871

Advancing to step 8:
5720 divided by 871 is 6 with a remainder of 494.
The next digit of our result is 6. 
Result so far: 33206.0
Subtracting 5226 from 5720 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 9:
4940 divided by 871 is 5 with a remainder of 585.
The number 5 becomes the next digit in our result. 
Result so far: 33206.5
If we take 4355 away from 4940, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

On to step 10:
871 can be fit into 5850 6 times, resulting in a remainder of 624.
The next digit of our result is 6. 
Result so far: 33206.56
If we take 5226 away from 5850, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Moving on to step 11:
The number 871 fits into 6240 7 times, leaving a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 33206.567
Subtracting 6097 from 6240 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 12:
871 can be fit into 1430 1 times, resulting in a remainder of 559.
The next digit of our result is 1. 
Result so far: 33206.5671
Deduct 871 from 1430 and we're left with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Advancing to step 13:
871 can be fit into 5590 6 times, resulting in a remainder of 364.
The next digit of our result is 6. 
Result so far: 33206.56716
If we take 5226 away from 5590, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 14:
871 goes into 3640 4 times with a remainder of 156.
Write down 4 as next digit of the result. 
Result so far: 33206.567164
Subtracting 3484 from 3640 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 15:
871 goes into 1560 1 times with a remainder of 689.
The next digit of our result is 1. 
Result so far: 33206.5671641
Deduct 871 from 1560 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Let's proceed to step 16:
If we divide 6890 by 871, we get 7 and a remainder of 793.
The next digit of our result is 7. 
Result so far: 33206.56716417
If we take 6097 away from 6890, we end up with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

The final outcome is 33206.56716417, with a leftover of 7.93e-07.
