We look at the division of 77294906 by 450 
The aim is to understand the frequency of 450 in 77294906.

Moving on to step 1:
The number 450 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 450

Step 2:
If we divide 77 by 450, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 450

Going ahead to step 3:
If we divide 772 by 450, we get 1 and a remainder of 322.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 450 from 772 to get 322.
Bring next digit (9) of the dividend behind the 322 and repeat the process: 3229 / 450

On to step 4:
3229 divided by 450 is 7 with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 3150 away from 3229, we end up with 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 450

On to step 5:
794 divided by 450 is 1 with a remainder of 344.
Use 1 as the next digit of our solution. 
Result so far: 171.0
If we subtract 450 from 794, we get 344.
Append the next digit (9) from the dividend to 344 and continue with: 3449 / 450

Step 6:
450 goes into 3449 7 times with a remainder of 299.
Use 7 as the next digit of our solution. 
Result so far: 1717.0
If we subtract 3150 from 3449, we get 299.
Append the next digit (0) from the dividend to 299 and continue with: 2990 / 450

Let's proceed to step 7:
The number 450 fits into 2990 6 times, leaving a remainder of 290.
Use 6 as the next digit of our solution. 
Result so far: 17176.0
Subtracting 2700 from 2990 leaves us with 290.
Bring next digit (6) of the dividend behind the 290 and repeat the process: 2906 / 450

Moving on to step 8:
If we divide 2906 by 450, we get 6 and a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 171766.0
The remainder is 206 after subtracting 2700 from 2906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 9:
When dividing 2060 by 450, we get 4 with a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 171766.4
If we take 1800 away from 2060, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
2600 divided by 450 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 171766.45
The remainder is 350 after subtracting 2250 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
The number 450 fits into 3500 7 times, leaving a remainder of 350.
Write down 7 as next digit of the result. 
Result so far: 171766.457
If we subtract 3150 from 3500, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 12:
When dividing 3500 by 450, we get 7 with a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 171766.4577
Subtract 3150 from 3500 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 171766.4577, with a leftover of 0.0035.
