We look at the division of 54498479 by 453 
The aim is to understand the frequency of 453 in 54498479.

Moving on to step 1:
The number 453 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 453

Step 2:
When dividing 54 by 453, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 453

Moving on to step 3:
453 can be fit into 544 1 times, resulting in a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 91 after subtracting 453 from 544.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 453

Let's proceed to step 4:
919 divided by 453 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 906 from 919, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 453

Advancing to step 5:
138 divided by 453 is 0 with a remainder of 138.
The next digit of our result is 0. 
Result so far: 120.0
If we take 0 away from 138, we end up with 138.
Include the next digit (4) from the dividend after 138, then repeat: 1384 / 453

Step 6:
When dividing 1384 by 453, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1203.0
Subtract 1359 from 1384 to get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 453

Going ahead to step 7:
453 goes into 257 0 times with a remainder of 257.
The next digit of our result is 0. 
Result so far: 12030.0
If we subtract 0 from 257, we get 257.
Take the next digit (9) from the dividend and append it to 257, then repeat: 2579 / 453

On to step 8:
453 goes into 2579 5 times with a remainder of 314.
The number 5 becomes the next digit in our result. 
Result so far: 120305.0
Deduct 2265 from 2579 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
The number 453 fits into 3140 6 times, leaving a remainder of 422.
Put 6 as the next digit of the answer. 
Result so far: 120305.6
Subtracting 2718 from 3140 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 10:
If we divide 4220 by 453, we get 9 and a remainder of 143.
The next digit of our result is 9. 
Result so far: 120305.69
If we subtract 4077 from 4220, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 11:
1430 divided by 453 is 3 with a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 120305.693
If we take 1359 away from 1430, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
If we divide 710 by 453, we get 1 and a remainder of 257.
Record the quotient 1 as the next digit in the result. 
Result so far: 120305.6931
Subtracting 453 from 710 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 13:
When dividing 2570 by 453, we get 5 with a remainder of 305.
The next digit of our result is 5. 
Result so far: 120305.69315
If we take 2265 away from 2570, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 14:
If we divide 3050 by 453, we get 6 and a remainder of 332.
Put 6 as the next digit of the answer. 
Result so far: 120305.693156
If we subtract 2718 from 3050, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 15:
453 can be fit into 3320 7 times, resulting in a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 120305.6931567
If we take 3171 away from 3320, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 16:
453 goes into 1490 3 times with a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 120305.69315673
The remainder is 131 after subtracting 1359 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The final result is 120305.69315673 with a remainder of 1.31e-07.
