We look at the division of 69997963 by 450 
The aim is to understand the frequency of 450 in 69997963.

Let's proceed to step 1:
6 divided by 450 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 450

Advancing to step 2:
When dividing 69 by 450, we get 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 450

Let's proceed to step 3:
450 can be fit into 699 1 times, resulting in a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 450 from 699 and we're left with 249.
Grab the next digit (9) from the dividend, add it to 249, then carry on: 2499 / 450

Advancing to step 4:
450 can be fit into 2499 5 times, resulting in a remainder of 249.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2250 from 2499 and we're left with 249.
Bring next digit (7) of the dividend behind the 249 and repeat the process: 2497 / 450

Going ahead to step 5:
450 can be fit into 2497 5 times, resulting in a remainder of 247.
The next digit of our result is 5. 
Result so far: 155.0
If we subtract 2250 from 2497, we get 247.
Append the next digit (9) from the dividend to 247 and continue with: 2479 / 450

On to step 6:
2479 divided by 450 is 5 with a remainder of 229.
The number 5 becomes the next digit in our result. 
Result so far: 1555.0
If we subtract 2250 from 2479, we get 229.
Append the next digit (6) from the dividend to 229 and continue with: 2296 / 450

Moving on to step 7:
When dividing 2296 by 450, we get 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 15555.0
If we subtract 2250 from 2296, we get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 450

Moving on to step 8:
If we divide 463 by 450, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 155551.0
Deduct 450 from 463 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
450 can be fit into 130 0 times, resulting in a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 155551.0
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
450 goes into 1300 2 times with a remainder of 400.
The number 2 becomes the next digit in our result. 
Result so far: 155551.02
Subtracting 900 from 1300 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
450 goes into 4000 8 times with a remainder of 400.
The next digit of our result is 8. 
Result so far: 155551.028
Subtract 3600 from 4000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
When dividing 4000 by 450, we get 8 with a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 155551.0288
If we take 3600 away from 4000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 155551.0288, and the remainder is 0.004.
