We look at the division of 20546485 by 852 
The aim is to understand the frequency of 852 in 20546485.

Step 1:
When dividing 2 by 852, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 852

Going ahead to step 2:
When dividing 20 by 852, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 852

On to step 3:
If we divide 205 by 852, we get 0 and a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Bring next digit (4) of the dividend behind the 205 and repeat the process: 2054 / 852

Let's proceed to step 4:
852 goes into 2054 2 times with a remainder of 350.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1704 from 2054 to get 350.
Fetch the next digit (6) from the dividend, attach it to 350 and continue: 3506 / 852

Going ahead to step 5:
When dividing 3506 by 852, we get 4 with a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 3408 from 3506, we get 98.
Bring next digit (4) of the dividend behind the 98 and repeat the process: 984 / 852

Step 6:
The number 852 fits into 984 1 times, leaving a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 241.0
The remainder is 132 after subtracting 852 from 984.
Take the next digit (8) from the dividend and append it to 132, then repeat: 1328 / 852

On to step 7:
852 can be fit into 1328 1 times, resulting in a remainder of 476.
Put 1 as the next digit of the answer. 
Result so far: 2411.0
If we subtract 852 from 1328, we get 476.
Fetch the next digit (5) from the dividend, attach it to 476 and continue: 4765 / 852

Advancing to step 8:
852 goes into 4765 5 times with a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 24115.0
If we take 4260 away from 4765, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 9:
If we divide 5050 by 852, we get 5 and a remainder of 790.
Use 5 as the next digit of our solution. 
Result so far: 24115.5
Subtract 4260 from 5050 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 10:
7900 divided by 852 is 9 with a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 24115.59
If we subtract 7668 from 7900, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 11:
If we divide 2320 by 852, we get 2 and a remainder of 616.
Use 2 as the next digit of our solution. 
Result so far: 24115.592
Subtract 1704 from 2320 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 12:
852 goes into 6160 7 times with a remainder of 196.
Put 7 as the next digit of the answer. 
Result so far: 24115.5927
Subtracting 5964 from 6160 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 13:
When dividing 1960 by 852, we get 2 with a remainder of 256.
The next digit of our result is 2. 
Result so far: 24115.59272
If we take 1704 away from 1960, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
852 goes into 2560 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 24115.592723
Subtracting 2556 from 2560 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 15:
When dividing 40 by 852, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 24115.592723
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
852 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 24115.592723
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 24115.592723, and the remainder is 4e-07.
