16237574 divided by 450 
The aim is to understand the frequency of 450 in 16237574.

Going ahead to step 1:
450 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 450

Advancing to step 2:
450 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 450

Advancing to step 3:
450 can be fit into 162 0 times, resulting in a remainder of 162.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 162, we get 162.
Append the next digit (3) from the dividend to 162 and continue with: 1623 / 450

Let's proceed to step 4:
450 can be fit into 1623 3 times, resulting in a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1350 from 1623 to get 273.
Grab the next digit (7) from the dividend, add it to 273, then carry on: 2737 / 450

Advancing to step 5:
450 goes into 2737 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 2700 from 2737 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 450

Let's proceed to step 6:
450 goes into 375 0 times with a remainder of 375.
Put 0 as the next digit of the answer. 
Result so far: 360.0
Subtract 0 from 375 to get 375.
Take the next digit (7) from the dividend and append it to 375, then repeat: 3757 / 450

Moving on to step 7:
450 can be fit into 3757 8 times, resulting in a remainder of 157.
The next digit of our result is 8. 
Result so far: 3608.0
If we take 3600 away from 3757, we end up with 157.
Grab the next digit (4) from the dividend, add it to 157, then carry on: 1574 / 450

Going ahead to step 8:
If we divide 1574 by 450, we get 3 and a remainder of 224.
Use 3 as the next digit of our solution. 
Result so far: 36083.0
Deduct 1350 from 1574 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.

Step 9:
When dividing 2240 by 450, we get 4 with a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 36083.4
Subtract 1800 from 2240 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 10:
If we divide 4400 by 450, we get 9 and a remainder of 350.
The number 9 becomes the next digit in our result. 
Result so far: 36083.49
Deduct 4050 from 4400 and we're left with 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 11:
The number 450 fits into 3500 7 times, leaving a remainder of 350.
Use 7 as the next digit of our solution. 
Result so far: 36083.497
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.

Step 12:
3500 divided by 450 is 7 with a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 36083.4977
Deduct 3150 from 3500 and we're left with 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 36083.4977, with a leftover of 0.0035.
