18043568 divided by 808 
The aim is to understand the frequency of 808 in 18043568.

Step 1:
1 divided by 808 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 808

Let's proceed to step 2:
18 divided by 808 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 808

Advancing to step 3:
808 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 180, we end up with 180.
Grab the next digit (4) from the dividend, add it to 180, then carry on: 1804 / 808

Step 4:
The number 808 fits into 1804 2 times, leaving a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1616 from 1804 leaves us with 188.
Include the next digit (3) from the dividend after 188, then repeat: 1883 / 808

Step 5:
808 can be fit into 1883 2 times, resulting in a remainder of 267.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 1616 from 1883, we get 267.
Fetch the next digit (5) from the dividend, attach it to 267 and continue: 2675 / 808

Advancing to step 6:
When dividing 2675 by 808, we get 3 with a remainder of 251.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
The remainder is 251 after subtracting 2424 from 2675.
Include the next digit (6) from the dividend after 251, then repeat: 2516 / 808

On to step 7:
808 can be fit into 2516 3 times, resulting in a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 2233.0
Subtracting 2424 from 2516 leaves us with 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 808

On to step 8:
When dividing 928 by 808, we get 1 with a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 22331.0
Subtracting 808 from 928 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 9:
The number 808 fits into 1200 1 times, leaving a remainder of 392.
The next digit of our result is 1. 
Result so far: 22331.1
Deduct 808 from 1200 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 10:
808 can be fit into 3920 4 times, resulting in a remainder of 688.
Record the quotient 4 as the next digit in the result. 
Result so far: 22331.14
If we subtract 3232 from 3920, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 11:
808 can be fit into 6880 8 times, resulting in a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 22331.148
The remainder is 416 after subtracting 6464 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 12:
4160 divided by 808 is 5 with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 22331.1485
Subtract 4040 from 4160 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
When dividing 1200 by 808, we get 1 with a remainder of 392.
Write down 1 as next digit of the result. 
Result so far: 22331.14851
Subtract 808 from 1200 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 14:
808 can be fit into 3920 4 times, resulting in a remainder of 688.
Write down 4 as next digit of the result. 
Result so far: 22331.148514
If we subtract 3232 from 3920, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 15:
The number 808 fits into 6880 8 times, leaving a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 22331.1485148
Subtracting 6464 from 6880 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 16:
808 can be fit into 4160 5 times, resulting in a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 22331.14851485
The remainder is 120 after subtracting 4040 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 22331.14851485, with a leftover of 1.2e-07.
