We divide 18681230 by 411
The aim is to understand the frequency of 411 in 18681230.

On to step 1:
When dividing 1 by 411, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 411

Let's proceed to step 2:
The number 411 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 411

On to step 3:
The number 411 fits into 186 0 times, leaving a remainder of 186.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Fetch the next digit (8) from the dividend, attach it to 186 and continue: 1868 / 411

Moving on to step 4:
411 can be fit into 1868 4 times, resulting in a remainder of 224.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1644 from 1868, we get 224.
Include the next digit (1) from the dividend after 224, then repeat: 2241 / 411

Going ahead to step 5:
2241 divided by 411 is 5 with a remainder of 186.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 2055 from 2241 leaves us with 186.
Bring next digit (2) of the dividend behind the 186 and repeat the process: 1862 / 411

Advancing to step 6:
The number 411 fits into 1862 4 times, leaving a remainder of 218.
Use 4 as the next digit of our solution. 
Result so far: 454.0
Subtract 1644 from 1862 to get 218.
Include the next digit (3) from the dividend after 218, then repeat: 2183 / 411

Moving on to step 7:
411 goes into 2183 5 times with a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 4545.0
Subtracting 2055 from 2183 leaves us with 128.
Append the next digit (0) from the dividend to 128 and continue with: 1280 / 411

Moving on to step 8:
The number 411 fits into 1280 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 45453.0
If we subtract 1233 from 1280, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
470 divided by 411 is 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 45453.1
If we subtract 411 from 470, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 10:
The number 411 fits into 590 1 times, leaving a remainder of 179.
Write down 1 as next digit of the result. 
Result so far: 45453.11
Deduct 411 from 590 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

After the division, we end up with 45453.11 and a remainder of 0.179.
