We're dividing 41891009 by 418 
The aim is to understand the frequency of 418 in 41891009.

Advancing to step 1:
418 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 418

Moving on to step 2:
If we divide 41 by 418, we get 0 and a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 418

Let's proceed to step 3:
418 goes into 418 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 418 from 418 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 418

Let's proceed to step 4:
When dividing 9 by 418, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 418

Step 5:
418 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 418

On to step 6:
When dividing 910 by 418, we get 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 1002.0
Subtract 836 from 910 to get 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 418

Step 7:
The number 418 fits into 740 1 times, leaving a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 10021.0
If we subtract 418 from 740, we get 322.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 418

Let's proceed to step 8:
418 can be fit into 3229 7 times, resulting in a remainder of 303.
The number 7 becomes the next digit in our result. 
Result so far: 100217.0
Subtract 2926 from 3229 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 9:
418 goes into 3030 7 times with a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 100217.7
If we take 2926 away from 3030, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
1040 divided by 418 is 2 with a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 100217.72
Deduct 836 from 1040 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 11:
The number 418 fits into 2040 4 times, leaving a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 100217.724
Deduct 1672 from 2040 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 12:
If we divide 3680 by 418, we get 8 and a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 100217.7248
Subtracting 3344 from 3680 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
418 can be fit into 3360 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 100217.72488
If we subtract 3344 from 3360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 100217.72488 and a remainder of 1.6e-05.
