Let's divide 17609257 by 450
The aim is to understand the frequency of 450 in 17609257.

Going ahead to step 1:
If we divide 1 by 450, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 450

Advancing to step 2:
When dividing 17 by 450, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 450

Step 3:
450 can be fit into 176 0 times, resulting in a remainder of 176.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 176 after subtracting 0 from 176.
Bring next digit (0) of the dividend behind the 176 and repeat the process: 1760 / 450

Let's proceed to step 4:
450 goes into 1760 3 times with a remainder of 410.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1350 from 1760 to get 410.
Fetch the next digit (9) from the dividend, attach it to 410 and continue: 4109 / 450

Advancing to step 5:
4109 divided by 450 is 9 with a remainder of 59.
The next digit of our result is 9. 
Result so far: 39.0
Deduct 4050 from 4109 and we're left with 59.
Bring next digit (2) of the dividend behind the 59 and repeat the process: 592 / 450

Going ahead to step 6:
The number 450 fits into 592 1 times, leaving a remainder of 142.
The next digit of our result is 1. 
Result so far: 391.0
The remainder is 142 after subtracting 450 from 592.
Fetch the next digit (5) from the dividend, attach it to 142 and continue: 1425 / 450

Let's proceed to step 7:
If we divide 1425 by 450, we get 3 and a remainder of 75.
The next digit of our result is 3. 
Result so far: 3913.0
If we subtract 1350 from 1425, we get 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 450

Advancing to step 8:
When dividing 757 by 450, we get 1 with a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 39131.0
Subtracting 450 from 757 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 9:
If we divide 3070 by 450, we get 6 and a remainder of 370.
Put 6 as the next digit of the answer. 
Result so far: 39131.6
Subtracting 2700 from 3070 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 10:
450 can be fit into 3700 8 times, resulting in a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 39131.68
Deduct 3600 from 3700 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
1000 divided by 450 is 2 with a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 39131.682
If we subtract 900 from 1000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
450 can be fit into 1000 2 times, resulting in a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 39131.6822
If we subtract 900 from 1000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 39131.6822, and the remainder is 0.001.
