53558694 divided by 871 
The aim is to understand the frequency of 871 in 53558694.

Advancing to step 1:
5 divided by 871 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 871

Advancing to step 2:
If we divide 53 by 871, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 871

Going ahead to step 3:
871 can be fit into 535 0 times, resulting in a remainder of 535.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 535, we get 535.
Include the next digit (5) from the dividend after 535, then repeat: 5355 / 871

Step 4:
If we divide 5355 by 871, we get 6 and a remainder of 129.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5226 away from 5355, we end up with 129.
Fetch the next digit (8) from the dividend, attach it to 129 and continue: 1298 / 871

Going ahead to step 5:
The number 871 fits into 1298 1 times, leaving a remainder of 427.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 871 away from 1298, we end up with 427.
Append the next digit (6) from the dividend to 427 and continue with: 4276 / 871

Let's proceed to step 6:
When dividing 4276 by 871, we get 4 with a remainder of 792.
Use 4 as the next digit of our solution. 
Result so far: 614.0
If we take 3484 away from 4276, we end up with 792.
Append the next digit (9) from the dividend to 792 and continue with: 7929 / 871

Advancing to step 7:
When dividing 7929 by 871, we get 9 with a remainder of 90.
Record the quotient 9 as the next digit in the result. 
Result so far: 6149.0
The remainder is 90 after subtracting 7839 from 7929.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 871

Moving on to step 8:
871 can be fit into 904 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 61491.0
If we subtract 871 from 904, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 871 fits into 330 0 times, leaving a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 61491.0
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
3300 divided by 871 is 3 with a remainder of 687.
Record the quotient 3 as the next digit in the result. 
Result so far: 61491.03
Subtract 2613 from 3300 to get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Step 11:
If we divide 6870 by 871, we get 7 and a remainder of 773.
The next digit of our result is 7. 
Result so far: 61491.037
Subtract 6097 from 6870 to get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Moving on to step 12:
The number 871 fits into 7730 8 times, leaving a remainder of 762.
Write down 8 as next digit of the result. 
Result so far: 61491.0378
Deduct 6968 from 7730 and we're left with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Going ahead to step 13:
The number 871 fits into 7620 8 times, leaving a remainder of 652.
The number 8 becomes the next digit in our result. 
Result so far: 61491.03788
If we take 6968 away from 7620, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The quotient of the division is 61491.03788, and the remainder is 0.000652.
