We're dividing 20513745 by 852 
The aim is to understand the frequency of 852 in 20513745.

Step 1:
When dividing 2 by 852, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 852

Let's proceed to step 2:
If we divide 20 by 852, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 852

Let's proceed to step 3:
The number 852 fits into 205 0 times, leaving a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Append the next digit (1) from the dividend to 205 and continue with: 2051 / 852

On to step 4:
If we divide 2051 by 852, we get 2 and a remainder of 347.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1704 from 2051 to get 347.
Grab the next digit (3) from the dividend, add it to 347, then carry on: 3473 / 852

On to step 5:
If we divide 3473 by 852, we get 4 and a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 3408 from 3473 and we're left with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 852

Moving on to step 6:
When dividing 657 by 852, we get 0 with a remainder of 657.
Put 0 as the next digit of the answer. 
Result so far: 240.0
If we subtract 0 from 657, we get 657.
Take the next digit (4) from the dividend and append it to 657, then repeat: 6574 / 852

Advancing to step 7:
If we divide 6574 by 852, we get 7 and a remainder of 610.
The next digit of our result is 7. 
Result so far: 2407.0
If we take 5964 away from 6574, we end up with 610.
Include the next digit (5) from the dividend after 610, then repeat: 6105 / 852

Moving on to step 8:
852 can be fit into 6105 7 times, resulting in a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 24077.0
If we take 5964 away from 6105, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 9:
1410 divided by 852 is 1 with a remainder of 558.
Put 1 as the next digit of the answer. 
Result so far: 24077.1
The remainder is 558 after subtracting 852 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 10:
852 goes into 5580 6 times with a remainder of 468.
Record the quotient 6 as the next digit in the result. 
Result so far: 24077.16
If we take 5112 away from 5580, we end up 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.

Going ahead to step 11:
852 goes into 4680 5 times with a remainder of 420.
The next digit of our result is 5. 
Result so far: 24077.165
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.

Advancing to step 12:
852 goes into 4200 4 times with a remainder of 792.
Record the quotient 4 as the next digit in the result. 
Result so far: 24077.1654
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.

Let's proceed to step 13:
If we divide 7920 by 852, we get 9 and a remainder of 252.
The number 9 becomes the next digit in our result. 
Result so far: 24077.16549
Subtracting 7668 from 7920 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 14:
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: 24077.165492
The remainder is 816 after subtracting 1704 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Going ahead to step 15:
852 goes into 8160 9 times with a remainder of 492.
Record the quotient 9 as the next digit in the result. 
Result so far: 24077.1654929
Subtracting 7668 from 8160 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 16:
4920 divided by 852 is 5 with a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 24077.16549295
If we take 4260 away from 4920, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

In conclusion, the division gives 24077.16549295 with a balance of 6.6e-07.
