88463898 ÷ 454 
The aim is to understand the frequency of 454 in 88463898.

Step 1:
8 divided by 454 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 454

Advancing to step 2:
If we divide 88 by 454, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 454

Going ahead to step 3:
454 can be fit into 884 1 times, resulting in a remainder of 430.
The next digit of our result is 1. 
Result so far: 1.0
If we take 454 away from 884, we end up with 430.
Grab the next digit (6) from the dividend, add it to 430, then carry on: 4306 / 454

Let's proceed to step 4:
454 goes into 4306 9 times with a remainder of 220.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 4086 from 4306 leaves us with 220.
Bring next digit (3) of the dividend behind the 220 and repeat the process: 2203 / 454

On to step 5:
When dividing 2203 by 454, we get 4 with a remainder of 387.
The next digit of our result is 4. 
Result so far: 194.0
If we subtract 1816 from 2203, we get 387.
Append the next digit (8) from the dividend to 387 and continue with: 3878 / 454

On to step 6:
The number 454 fits into 3878 8 times, leaving a remainder of 246.
Write down 8 as next digit of the result. 
Result so far: 1948.0
The remainder is 246 after subtracting 3632 from 3878.
Fetch the next digit (9) from the dividend, attach it to 246 and continue: 2469 / 454

Let's proceed to step 7:
454 goes into 2469 5 times with a remainder of 199.
The number 5 becomes the next digit in our result. 
Result so far: 19485.0
Deduct 2270 from 2469 and we're left with 199.
Include the next digit (8) from the dividend after 199, then repeat: 1998 / 454

Step 8:
When dividing 1998 by 454, we get 4 with a remainder of 182.
Write down 4 as next digit of the result. 
Result so far: 194854.0
Subtracting 1816 from 1998 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
If we divide 1820 by 454, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 194854.4
If we take 1816 away from 1820, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 454 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 194854.4
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 454 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 194854.4
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 194854.4 and a remainder of 0.04.
