We look at the division of 13843739 by 450 
The aim is to understand the frequency of 450 in 13843739.

Let's proceed to step 1:
450 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 450

Let's proceed to step 2:
13 divided by 450 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 450

On to step 3:
450 goes into 138 0 times with a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 450

Advancing to step 4:
1384 divided by 450 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 34 after subtracting 1350 from 1384.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 450

Going ahead to step 5:
The number 450 fits into 343 0 times, leaving a remainder of 343.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 343 and we're left with 343.
Fetch the next digit (7) from the dividend, attach it to 343 and continue: 3437 / 450

Moving on to step 6:
The number 450 fits into 3437 7 times, leaving a remainder of 287.
Write down 7 as next digit of the result. 
Result so far: 307.0
If we subtract 3150 from 3437, we get 287.
Fetch the next digit (3) from the dividend, attach it to 287 and continue: 2873 / 450

Step 7:
When dividing 2873 by 450, we get 6 with a remainder of 173.
Use 6 as the next digit of our solution. 
Result so far: 3076.0
The remainder is 173 after subtracting 2700 from 2873.
Append the next digit (9) from the dividend to 173 and continue with: 1739 / 450

Let's proceed to step 8:
450 can be fit into 1739 3 times, resulting in a remainder of 389.
Record the quotient 3 as the next digit in the result. 
Result so far: 30763.0
If we take 1350 away from 1739, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 9:
450 goes into 3890 8 times with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 30763.8
Deduct 3600 from 3890 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
2900 divided by 450 is 6 with a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 30763.86
Subtracting 2700 from 2900 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
450 goes into 2000 4 times with a remainder of 200.
The next digit of our result is 4. 
Result so far: 30763.864
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
2000 divided by 450 is 4 with a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 30763.8644
Subtract 1800 from 2000 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 30763.8644, and the remainder is 0.002.
