We look at the division of 12714714 by 852 
The aim is to understand the frequency of 852 in 12714714.

Going ahead to step 1:
When dividing 1 by 852, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 852

On to step 2:
The number 852 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 852

Going ahead to step 3:
852 can be fit into 127 0 times, resulting in a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Include the next digit (1) from the dividend after 127, then repeat: 1271 / 852

Going ahead to step 4:
If we divide 1271 by 852, we get 1 and a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 852 from 1271, we get 419.
Take the next digit (4) from the dividend and append it to 419, then repeat: 4194 / 852

Step 5:
If we divide 4194 by 852, we get 4 and a remainder of 786.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 786 after subtracting 3408 from 4194.
Fetch the next digit (7) from the dividend, attach it to 786 and continue: 7867 / 852

On to step 6:
The number 852 fits into 7867 9 times, leaving a remainder of 199.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Deduct 7668 from 7867 and we're left with 199.
Include the next digit (1) from the dividend after 199, then repeat: 1991 / 852

Moving on to step 7:
If we divide 1991 by 852, we get 2 and a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 1492.0
Subtracting 1704 from 1991 leaves us with 287.
Append the next digit (4) from the dividend to 287 and continue with: 2874 / 852

On to step 8:
2874 divided by 852 is 3 with a remainder of 318.
The number 3 becomes the next digit in our result. 
Result so far: 14923.0
The remainder is 318 after subtracting 2556 from 2874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 9:
If we divide 3180 by 852, we get 3 and a remainder of 624.
Record the quotient 3 as the next digit in the result. 
Result so far: 14923.3
If we subtract 2556 from 3180, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 10:
The number 852 fits into 6240 7 times, leaving a remainder of 276.
The next digit of our result is 7. 
Result so far: 14923.37
Subtract 5964 from 6240 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 11:
852 goes into 2760 3 times with a remainder of 204.
Put 3 as the next digit of the answer. 
Result so far: 14923.373
The remainder is 204 after subtracting 2556 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 12:
852 goes into 2040 2 times with a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 14923.3732
Subtracting 1704 from 2040 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 13:
If we divide 3360 by 852, we get 3 and a remainder of 804.
Put 3 as the next digit of the answer. 
Result so far: 14923.37323
If we subtract 2556 from 3360, we get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Moving on to step 14:
When dividing 8040 by 852, we get 9 with a remainder of 372.
Write down 9 as next digit of the result. 
Result so far: 14923.373239
Subtract 7668 from 8040 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 15:
3720 divided by 852 is 4 with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 14923.3732394
If we take 3408 away from 3720, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 16:
852 goes into 3120 3 times with a remainder of 564.
The number 3 becomes the next digit in our result. 
Result so far: 14923.37323943
The remainder is 564 after subtracting 2556 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The final outcome is 14923.37323943, with a leftover of 5.64e-07.
