81127908 ÷ 852 
The aim is to understand the frequency of 852 in 81127908.

On to step 1:
When dividing 8 by 852, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 852

Moving on to step 2:
852 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 852

Going ahead to step 3:
The number 852 fits into 811 0 times, leaving a remainder of 811.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 811 to get 811.
Append the next digit (2) from the dividend to 811 and continue with: 8112 / 852

Advancing to step 4:
When dividing 8112 by 852, we get 9 with a remainder of 444.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 444 after subtracting 7668 from 8112.
Append the next digit (7) from the dividend to 444 and continue with: 4447 / 852

Let's proceed to step 5:
When dividing 4447 by 852, we get 5 with a remainder of 187.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtracting 4260 from 4447 leaves us with 187.
Fetch the next digit (9) from the dividend, attach it to 187 and continue: 1879 / 852

Let's proceed to step 6:
852 can be fit into 1879 2 times, resulting in a remainder of 175.
Record the quotient 2 as the next digit in the result. 
Result so far: 952.0
Subtracting 1704 from 1879 leaves us with 175.
Append the next digit (0) from the dividend to 175 and continue with: 1750 / 852

Moving on to step 7:
When dividing 1750 by 852, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 9522.0
Subtracting 1704 from 1750 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 852

Advancing to step 8:
When dividing 468 by 852, we get 0 with a remainder of 468.
Put 0 as the next digit of the answer. 
Result so far: 95220.0
Subtracting 0 from 468 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 9:
The number 852 fits into 4680 5 times, leaving a remainder of 420.
Write down 5 as next digit of the result. 
Result so far: 95220.5
Subtracting 4260 from 4680 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
852 can be fit into 4200 4 times, resulting in a remainder of 792.
Record the quotient 4 as the next digit in the result. 
Result so far: 95220.54
If we subtract 3408 from 4200, we get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 11:
7920 divided by 852 is 9 with a remainder of 252.
The number 9 becomes the next digit in our result. 
Result so far: 95220.549
The remainder is 252 after subtracting 7668 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 12:
The number 852 fits into 2520 2 times, leaving a remainder of 816.
Use 2 as the next digit of our solution. 
Result so far: 95220.5492
Subtracting 1704 from 2520 leaves us with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 13:
8160 divided by 852 is 9 with a remainder of 492.
Use 9 as the next digit of our solution. 
Result so far: 95220.54929
Subtract 7668 from 8160 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Advancing to step 14:
The number 852 fits into 4920 5 times, leaving a remainder of 660.
The number 5 becomes the next digit in our result. 
Result so far: 95220.549295
The remainder is 660 after subtracting 4260 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 15:
If we divide 6600 by 852, we get 7 and a remainder of 636.
Put 7 as the next digit of the answer. 
Result so far: 95220.5492957
If we take 5964 away from 6600, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 16:
6360 divided by 852 is 7 with a remainder of 396.
Record the quotient 7 as the next digit in the result. 
Result so far: 95220.54929577
If we take 5964 away from 6360, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The final result is 95220.54929577 with a remainder of 3.96e-07.
