We look at the division of 91735569 by 454 
The aim is to understand the frequency of 454 in 91735569.

On to step 1:
The number 454 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 454

Step 2:
454 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 454

Step 3:
When dividing 917 by 454, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 908 from 917 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 454

On to step 4:
If we divide 93 by 454, we get 0 and a remainder of 93.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 93 after subtracting 0 from 93.
Take the next digit (5) from the dividend and append it to 93, then repeat: 935 / 454

Advancing to step 5:
454 can be fit into 935 2 times, resulting in a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
If we subtract 908 from 935, we get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 454

Step 6:
454 goes into 275 0 times with a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 2020.0
If we subtract 0 from 275, we get 275.
Take the next digit (6) from the dividend and append it to 275, then repeat: 2756 / 454

Moving on to step 7:
454 goes into 2756 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 20206.0
If we take 2724 away from 2756, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 454

Let's proceed to step 8:
The number 454 fits into 329 0 times, leaving a remainder of 329.
Record the quotient 0 as the next digit in the result. 
Result so far: 202060.0
Subtract 0 from 329 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
3290 divided by 454 is 7 with a remainder of 112.
The next digit of our result is 7. 
Result so far: 202060.7
The remainder is 112 after subtracting 3178 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
1120 divided by 454 is 2 with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 202060.72
If we subtract 908 from 1120, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 11:
When dividing 2120 by 454, we get 4 with a remainder of 304.
The next digit of our result is 4. 
Result so far: 202060.724
If we subtract 1816 from 2120, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 12:
3040 divided by 454 is 6 with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 202060.7246
If we subtract 2724 from 3040, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 13:
454 can be fit into 3160 6 times, resulting in a remainder of 436.
Put 6 as the next digit of the answer. 
Result so far: 202060.72466
Subtract 2724 from 3160 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The quotient of the division is 202060.72466, and the remainder is 0.000436.
