We divide 18621108 by 449
The aim is to understand the frequency of 449 in 18621108.

Let's proceed to step 1:
The number 449 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 449

Moving on to step 2:
The number 449 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 449

Advancing to step 3:
If we divide 186 by 449, we get 0 and a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 186, we get 186.
Append the next digit (2) from the dividend to 186 and continue with: 1862 / 449

Moving on to step 4:
If we divide 1862 by 449, we get 4 and a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1796 from 1862, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 449

On to step 5:
661 divided by 449 is 1 with a remainder of 212.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 449 from 661 to get 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 449

Moving on to step 6:
When dividing 2121 by 449, we get 4 with a remainder of 325.
Put 4 as the next digit of the answer. 
Result so far: 414.0
If we subtract 1796 from 2121, we get 325.
Bring next digit (0) of the dividend behind the 325 and repeat the process: 3250 / 449

Let's proceed to step 7:
When dividing 3250 by 449, we get 7 with a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 4147.0
Deduct 3143 from 3250 and we're left with 107.
Include the next digit (8) from the dividend after 107, then repeat: 1078 / 449

Moving on to step 8:
When dividing 1078 by 449, we get 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 41472.0
If we subtract 898 from 1078, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 9:
449 can be fit into 1800 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 41472.4
If we subtract 1796 from 1800, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 449, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 41472.4
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
449 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 41472.4
If we take 0 away from 400, 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.

After the division, we end up with 41472.4 and a remainder of 0.04.
