We look at the division of 65213640 by 453 
The aim is to understand the frequency of 453 in 65213640.

Advancing to step 1:
6 divided by 453 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 453

Let's proceed to step 2:
65 divided by 453 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 453

Advancing to step 3:
652 divided by 453 is 1 with a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 453 away from 652, we end up with 199.
Fetch the next digit (1) from the dividend, attach it to 199 and continue: 1991 / 453

Let's proceed to step 4:
1991 divided by 453 is 4 with a remainder of 179.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 1812 from 1991 to get 179.
Include the next digit (3) from the dividend after 179, then repeat: 1793 / 453

Advancing to step 5:
When dividing 1793 by 453, we get 3 with a remainder of 434.
Write down 3 as next digit of the result. 
Result so far: 143.0
Deduct 1359 from 1793 and we're left with 434.
Grab the next digit (6) from the dividend, add it to 434, then carry on: 4346 / 453

Going ahead to step 6:
4346 divided by 453 is 9 with a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 1439.0
If we subtract 4077 from 4346, we get 269.
Fetch the next digit (4) from the dividend, attach it to 269 and continue: 2694 / 453

Step 7:
When dividing 2694 by 453, we get 5 with a remainder of 429.
Write down 5 as next digit of the result. 
Result so far: 14395.0
Deduct 2265 from 2694 and we're left with 429.
Bring next digit (0) of the dividend behind the 429 and repeat the process: 4290 / 453

Going ahead to step 8:
453 goes into 4290 9 times with a remainder of 213.
Record the quotient 9 as the next digit in the result. 
Result so far: 143959.0
The remainder is 213 after subtracting 4077 from 4290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 9:
453 goes into 2130 4 times with a remainder of 318.
Put 4 as the next digit of the answer. 
Result so far: 143959.4
Deduct 1812 from 2130 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 10:
453 goes into 3180 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 143959.47
Subtract 3171 from 3180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
453 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 143959.47
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
453 can be fit into 900 1 times, resulting in a remainder of 447.
The number 1 becomes the next digit in our result. 
Result so far: 143959.4701
Subtracting 453 from 900 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 13:
453 can be fit into 4470 9 times, resulting in a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 143959.47019
Subtract 4077 from 4470 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 14:
If we divide 3930 by 453, we get 8 and a remainder of 306.
Write down 8 as next digit of the result. 
Result so far: 143959.470198
If we take 3624 away from 3930, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 15:
3060 divided by 453 is 6 with a remainder of 342.
Record the quotient 6 as the next digit in the result. 
Result so far: 143959.4701986
Deduct 2718 from 3060 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 16:
When dividing 3420 by 453, we get 7 with a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 143959.47019867
If we take 3171 away from 3420, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

The final result is 143959.47019867 with a remainder of 2.49e-07.
