We look at the division of 63843144 by 452 
The aim is to understand the frequency of 452 in 63843144.

Going ahead to step 1:
6 divided by 452 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 452

On to step 2:
If we divide 63 by 452, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (8) of the dividend behind the 63 and repeat the process: 638 / 452

Advancing to step 3:
When dividing 638 by 452, we get 1 with a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 452 away from 638, we end up with 186.
Append the next digit (4) from the dividend to 186 and continue with: 1864 / 452

Step 4:
The number 452 fits into 1864 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 1808 from 1864, we get 56.
Bring next digit (3) of the dividend behind the 56 and repeat the process: 563 / 452

Moving on to step 5:
452 can be fit into 563 1 times, resulting in a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 141.0
If we take 452 away from 563, we end up with 111.
Bring next digit (1) of the dividend behind the 111 and repeat the process: 1111 / 452

Going ahead to step 6:
When dividing 1111 by 452, we get 2 with a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 1412.0
Deduct 904 from 1111 and we're left with 207.
Append the next digit (4) from the dividend to 207 and continue with: 2074 / 452

Advancing to step 7:
If we divide 2074 by 452, we get 4 and a remainder of 266.
The next digit of our result is 4. 
Result so far: 14124.0
If we take 1808 away from 2074, we end up with 266.
Append the next digit (4) from the dividend to 266 and continue with: 2664 / 452

Let's proceed to step 8:
If we divide 2664 by 452, we get 5 and a remainder of 404.
Record the quotient 5 as the next digit in the result. 
Result so far: 141245.0
If we take 2260 away from 2664, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 9:
4040 divided by 452 is 8 with a remainder of 424.
The next digit of our result is 8. 
Result so far: 141245.8
If we subtract 3616 from 4040, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 10:
452 goes into 4240 9 times with a remainder of 172.
Put 9 as the next digit of the answer. 
Result so far: 141245.89
Subtract 4068 from 4240 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
452 goes into 1720 3 times with a remainder of 364.
Put 3 as the next digit of the answer. 
Result so far: 141245.893
Deduct 1356 from 1720 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 12:
The number 452 fits into 3640 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 141245.8938
Deduct 3616 from 3640 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 452 fits into 240 0 times, leaving a remainder of 240.
The next digit of our result is 0. 
Result so far: 141245.8938
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
If we divide 2400 by 452, we get 5 and a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 141245.893805
The remainder is 140 after subtracting 2260 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
452 can be fit into 1400 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 141245.8938053
The remainder is 44 after subtracting 1356 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 16:
452 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 141245.8938053
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 141245.8938053 with a remaining 4.4e-07.
