We're dividing 18880278 by 911 
The aim is to understand the frequency of 911 in 18880278.

Going ahead to step 1:
911 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 911

Let's proceed to step 2:
911 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 911

Going ahead to step 3:
The number 911 fits into 188 0 times, leaving a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 188 leaves us with 188.
Append the next digit (8) from the dividend to 188 and continue with: 1888 / 911

On to step 4:
911 goes into 1888 2 times with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1822 from 1888 leaves us with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 911

Step 5:
660 divided by 911 is 0 with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 660, we get 660.
Append the next digit (2) from the dividend to 660 and continue with: 6602 / 911

Step 6:
The number 911 fits into 6602 7 times, leaving a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 207.0
The remainder is 225 after subtracting 6377 from 6602.
Take the next digit (7) from the dividend and append it to 225, then repeat: 2257 / 911

Step 7:
If we divide 2257 by 911, we get 2 and a remainder of 435.
Record the quotient 2 as the next digit in the result. 
Result so far: 2072.0
The remainder is 435 after subtracting 1822 from 2257.
Include the next digit (8) from the dividend after 435, then repeat: 4358 / 911

Moving on to step 8:
When dividing 4358 by 911, we get 4 with a remainder of 714.
Record the quotient 4 as the next digit in the result. 
Result so far: 20724.0
Subtract 3644 from 4358 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Let's proceed to step 9:
911 goes into 7140 7 times with a remainder of 763.
Put 7 as the next digit of the answer. 
Result so far: 20724.7
Subtracting 6377 from 7140 leaves us with 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Advancing to step 10:
If we divide 7630 by 911, we get 8 and a remainder of 342.
The next digit of our result is 8. 
Result so far: 20724.78
If we subtract 7288 from 7630, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 11:
If we divide 3420 by 911, we get 3 and a remainder of 687.
Put 3 as the next digit of the answer. 
Result so far: 20724.783
If we subtract 2733 from 3420, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Moving on to step 12:
6870 divided by 911 is 7 with a remainder of 493.
The number 7 becomes the next digit in our result. 
Result so far: 20724.7837
Subtracting 6377 from 6870 leaves us with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 13:
4930 divided by 911 is 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 20724.78375
Deduct 4555 from 4930 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 14:
If we divide 3750 by 911, we get 4 and a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 20724.783754
Deduct 3644 from 3750 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 15:
If we divide 1060 by 911, we get 1 and a remainder of 149.
The next digit of our result is 1. 
Result so far: 20724.7837541
The remainder is 149 after subtracting 911 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 16:
1490 divided by 911 is 1 with a remainder of 579.
The number 1 becomes the next digit in our result. 
Result so far: 20724.78375411
The remainder is 579 after subtracting 911 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

The final result is 20724.78375411 with a remainder of 5.79e-07.
