We're dividing 87881923 by 852 
The aim is to understand the frequency of 852 in 87881923.

Advancing to step 1:
8 divided by 852 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 852

Going ahead to step 2:
If we divide 87 by 852, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 852

Let's proceed to step 3:
852 goes into 878 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 852 from 878 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 852

Going ahead to step 4:
When dividing 268 by 852, we get 0 with a remainder of 268.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 268, we end up with 268.
Bring next digit (1) of the dividend behind the 268 and repeat the process: 2681 / 852

Advancing to step 5:
2681 divided by 852 is 3 with a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtracting 2556 from 2681 leaves us with 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 852

Let's proceed to step 6:
852 goes into 1259 1 times with a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 1031.0
Subtract 852 from 1259 to get 407.
Grab the next digit (2) from the dividend, add it to 407, then carry on: 4072 / 852

Advancing to step 7:
The number 852 fits into 4072 4 times, leaving a remainder of 664.
Put 4 as the next digit of the answer. 
Result so far: 10314.0
If we subtract 3408 from 4072, we get 664.
Fetch the next digit (3) from the dividend, attach it to 664 and continue: 6643 / 852

Step 8:
852 goes into 6643 7 times with a remainder of 679.
The number 7 becomes the next digit in our result. 
Result so far: 103147.0
Subtracting 5964 from 6643 leaves us with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Advancing to step 9:
852 goes into 6790 7 times with a remainder of 826.
The next digit of our result is 7. 
Result so far: 103147.7
If we subtract 5964 from 6790, we get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Let's proceed to step 10:
8260 divided by 852 is 9 with a remainder of 592.
Write down 9 as next digit of the result. 
Result so far: 103147.79
Subtracting 7668 from 8260 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 11:
When dividing 5920 by 852, we get 6 with a remainder of 808.
Record the quotient 6 as the next digit in the result. 
Result so far: 103147.796
The remainder is 808 after subtracting 5112 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 12:
If we divide 8080 by 852, we get 9 and a remainder of 412.
Record the quotient 9 as the next digit in the result. 
Result so far: 103147.7969
Subtracting 7668 from 8080 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 13:
If we divide 4120 by 852, we get 4 and a remainder of 712.
Put 4 as the next digit of the answer. 
Result so far: 103147.79694
If we take 3408 away from 4120, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 14:
When dividing 7120 by 852, we get 8 with a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 103147.796948
If we take 6816 away from 7120, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 15:
3040 divided by 852 is 3 with a remainder of 484.
Put 3 as the next digit of the answer. 
Result so far: 103147.7969483
Subtracting 2556 from 3040 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 16:
852 goes into 4840 5 times with a remainder of 580.
Use 5 as the next digit of our solution. 
Result so far: 103147.79694835
The remainder is 580 after subtracting 4260 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Our division results in 103147.79694835 with a remaining 5.8e-07.
