We're dividing 84123196 by 453 
The aim is to understand the frequency of 453 in 84123196.

Let's proceed to step 1:
453 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 453

Step 2:
453 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 453

Let's proceed to step 3:
841 divided by 453 is 1 with a remainder of 388.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 453 from 841 and we're left with 388.
Include the next digit (2) from the dividend after 388, then repeat: 3882 / 453

Moving on to step 4:
If we divide 3882 by 453, we get 8 and a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3624 from 3882 to get 258.
Fetch the next digit (3) from the dividend, attach it to 258 and continue: 2583 / 453

Moving on to step 5:
453 can be fit into 2583 5 times, resulting in a remainder of 318.
The next digit of our result is 5. 
Result so far: 185.0
Deduct 2265 from 2583 and we're left with 318.
Take the next digit (1) from the dividend and append it to 318, then repeat: 3181 / 453

Step 6:
453 can be fit into 3181 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1857.0
If we subtract 3171 from 3181, we get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 453

Let's proceed to step 7:
The number 453 fits into 109 0 times, leaving a remainder of 109.
Use 0 as the next digit of our solution. 
Result so far: 18570.0
The remainder is 109 after subtracting 0 from 109.
Append the next digit (6) from the dividend to 109 and continue with: 1096 / 453

Going ahead to step 8:
If we divide 1096 by 453, we get 2 and a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 185702.0
If we take 906 away from 1096, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 9:
If we divide 1900 by 453, we get 4 and a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 185702.4
Subtract 1812 from 1900 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
453 goes into 880 1 times with a remainder of 427.
The next digit of our result is 1. 
Result so far: 185702.41
Subtract 453 from 880 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 11:
When dividing 4270 by 453, we get 9 with a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 185702.419
Subtract 4077 from 4270 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 12:
453 can be fit into 1930 4 times, resulting in a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 185702.4194
Subtracting 1812 from 1930 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 13:
453 goes into 1180 2 times with a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 185702.41942
If we subtract 906 from 1180, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 14:
453 goes into 2740 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 185702.419426
If we subtract 2718 from 2740, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
When dividing 220 by 453, we get 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 185702.419426
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 16:
The number 453 fits into 2200 4 times, leaving a remainder of 388.
The next digit of our result is 4. 
Result so far: 185702.41942604
If we take 1812 away from 2200, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 185702.41942604, with a leftover of 3.88e-07.
