52513158 divided by 450 
The aim is to understand the frequency of 450 in 52513158.

On to step 1:
The number 450 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 450

Let's proceed to step 2:
When dividing 52 by 450, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 450

Going ahead to step 3:
525 divided by 450 is 1 with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 450 from 525, we get 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 450

Moving on to step 4:
450 can be fit into 751 1 times, resulting in a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 450 from 751 to get 301.
Bring next digit (3) of the dividend behind the 301 and repeat the process: 3013 / 450

Moving on to step 5:
3013 divided by 450 is 6 with a remainder of 313.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtract 2700 from 3013 to get 313.
Append the next digit (1) from the dividend to 313 and continue with: 3131 / 450

Going ahead to step 6:
The number 450 fits into 3131 6 times, leaving a remainder of 431.
The next digit of our result is 6. 
Result so far: 1166.0
Deduct 2700 from 3131 and we're left with 431.
Fetch the next digit (5) from the dividend, attach it to 431 and continue: 4315 / 450

On to step 7:
When dividing 4315 by 450, we get 9 with a remainder of 265.
Write down 9 as next digit of the result. 
Result so far: 11669.0
The remainder is 265 after subtracting 4050 from 4315.
Append the next digit (8) from the dividend to 265 and continue with: 2658 / 450

Advancing to step 8:
The number 450 fits into 2658 5 times, leaving a remainder of 408.
Record the quotient 5 as the next digit in the result. 
Result so far: 116695.0
Subtract 2250 from 2658 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 9:
450 goes into 4080 9 times with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 116695.9
If we take 4050 away from 4080, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 450 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 116695.9
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
If we divide 3000 by 450, we get 6 and a remainder of 300.
The next digit of our result is 6. 
Result so far: 116695.906
If we subtract 2700 from 3000, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 12:
450 can be fit into 3000 6 times, resulting in a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 116695.9066
Deduct 2700 from 3000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 116695.9066, with a leftover of 0.003.
