We look at the division of 34424873 by 453 
The aim is to understand the frequency of 453 in 34424873.

Going ahead to step 1:
3 divided by 453 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 453

Moving on to step 2:
453 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 453

Moving on to step 3:
453 goes into 344 0 times with a remainder of 344.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 344 after subtracting 0 from 344.
Bring next digit (2) of the dividend behind the 344 and repeat the process: 3442 / 453

Moving on to step 4:
The number 453 fits into 3442 7 times, leaving a remainder of 271.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 3171 from 3442 to get 271.
Take the next digit (4) from the dividend and append it to 271, then repeat: 2714 / 453

Going ahead to step 5:
If we divide 2714 by 453, we get 5 and a remainder of 449.
The next digit of our result is 5. 
Result so far: 75.0
If we take 2265 away from 2714, we end up with 449.
Take the next digit (8) from the dividend and append it to 449, then repeat: 4498 / 453

On to step 6:
453 can be fit into 4498 9 times, resulting in a remainder of 421.
The next digit of our result is 9. 
Result so far: 759.0
If we subtract 4077 from 4498, we get 421.
Fetch the next digit (7) from the dividend, attach it to 421 and continue: 4217 / 453

Step 7:
453 can be fit into 4217 9 times, resulting in a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 7599.0
Subtracting 4077 from 4217 leaves us with 140.
Fetch the next digit (3) from the dividend, attach it to 140 and continue: 1403 / 453

Going ahead to step 8:
The number 453 fits into 1403 3 times, leaving a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 75993.0
The remainder is 44 after subtracting 1359 from 1403.
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 9:
If we divide 440 by 453, we get 0 and a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 75993.0
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
453 can be fit into 4400 9 times, resulting in a remainder of 323.
Write down 9 as next digit of the result. 
Result so far: 75993.09
If we take 4077 away from 4400, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 11:
If we divide 3230 by 453, we get 7 and a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 75993.097
Subtracting 3171 from 3230 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 12:
The number 453 fits into 590 1 times, leaving a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 75993.0971
If we take 453 away from 590, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 13:
453 can be fit into 1370 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 75993.09713
Deduct 1359 from 1370 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
When dividing 110 by 453, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 75993.09713
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
The number 453 fits into 1100 2 times, leaving a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 75993.0971302
The remainder is 194 after subtracting 906 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 16:
The number 453 fits into 1940 4 times, leaving a remainder of 128.
The next digit of our result is 4. 
Result so far: 75993.09713024
If we take 1812 away from 1940, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 75993.09713024, with a leftover of 1.28e-07.
