67749805 ÷ 454 
The aim is to understand the frequency of 454 in 67749805.

Step 1:
When dividing 6 by 454, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 454

Going ahead to step 2:
454 can be fit into 67 0 times, resulting in a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 454

Going ahead to step 3:
When dividing 677 by 454, we get 1 with a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 454 from 677 to get 223.
Grab the next digit (4) from the dividend, add it to 223, then carry on: 2234 / 454

Going ahead to step 4:
454 can be fit into 2234 4 times, resulting in a remainder of 418.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 1816 away from 2234, we end up with 418.
Grab the next digit (9) from the dividend, add it to 418, then carry on: 4189 / 454

On to step 5:
When dividing 4189 by 454, we get 9 with a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 149.0
The remainder is 103 after subtracting 4086 from 4189.
Append the next digit (8) from the dividend to 103 and continue with: 1038 / 454

On to step 6:
454 goes into 1038 2 times with a remainder of 130.
The next digit of our result is 2. 
Result so far: 1492.0
Subtracting 908 from 1038 leaves us with 130.
Append the next digit (0) from the dividend to 130 and continue with: 1300 / 454

Going ahead to step 7:
If we divide 1300 by 454, we get 2 and a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 14922.0
Subtracting 908 from 1300 leaves us with 392.
Include the next digit (5) from the dividend after 392, then repeat: 3925 / 454

Going ahead to step 8:
The number 454 fits into 3925 8 times, leaving a remainder of 293.
Write down 8 as next digit of the result. 
Result so far: 149228.0
The remainder is 293 after subtracting 3632 from 3925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
454 can be fit into 2930 6 times, resulting in a remainder of 206.
Put 6 as the next digit of the answer. 
Result so far: 149228.6
If we subtract 2724 from 2930, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 10:
2060 divided by 454 is 4 with a remainder of 244.
Write down 4 as next digit of the result. 
Result so far: 149228.64
Subtracting 1816 from 2060 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
454 can be fit into 2440 5 times, resulting in a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 149228.645
If we subtract 2270 from 2440, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 12:
The number 454 fits into 1700 3 times, leaving a remainder of 338.
Put 3 as the next digit of the answer. 
Result so far: 149228.6453
Subtract 1362 from 1700 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 13:
If we divide 3380 by 454, we get 7 and a remainder of 202.
Record the quotient 7 as the next digit in the result. 
Result so far: 149228.64537
The remainder is 202 after subtracting 3178 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 14:
2020 divided by 454 is 4 with a remainder of 204.
The next digit of our result is 4. 
Result so far: 149228.645374
The remainder is 204 after subtracting 1816 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 15:
454 can be fit into 2040 4 times, resulting in a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 149228.6453744
Deduct 1816 from 2040 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final outcome is 149228.6453744, with a leftover of 2.24e-06.
