We look at the division of 16818108 by 574 
The aim is to understand the frequency of 574 in 16818108.

Going ahead to step 1:
If we divide 1 by 574, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 574

Moving on to step 2:
574 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 574

Advancing to step 3:
If we divide 168 by 574, we get 0 and a remainder of 168.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 168 to get 168.
Take the next digit (1) from the dividend and append it to 168, then repeat: 1681 / 574

Going ahead to step 4:
The number 574 fits into 1681 2 times, leaving a remainder of 533.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1148 from 1681, we get 533.
Grab the next digit (8) from the dividend, add it to 533, then carry on: 5338 / 574

Going ahead to step 5:
When dividing 5338 by 574, we get 9 with a remainder of 172.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 5166 from 5338 leaves us with 172.
Bring next digit (1) of the dividend behind the 172 and repeat the process: 1721 / 574

Moving on to step 6:
574 goes into 1721 2 times with a remainder of 573.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
Subtract 1148 from 1721 to get 573.
Include the next digit (0) from the dividend after 573, then repeat: 5730 / 574

Advancing to step 7:
The number 574 fits into 5730 9 times, leaving a remainder of 564.
The next digit of our result is 9. 
Result so far: 2929.0
The remainder is 564 after subtracting 5166 from 5730.
Fetch the next digit (8) from the dividend, attach it to 564 and continue: 5648 / 574

Advancing to step 8:
The number 574 fits into 5648 9 times, leaving a remainder of 482.
The number 9 becomes the next digit in our result. 
Result so far: 29299.0
Deduct 5166 from 5648 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 9:
574 can be fit into 4820 8 times, resulting in a remainder of 228.
Put 8 as the next digit of the answer. 
Result so far: 29299.8
The remainder is 228 after subtracting 4592 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
574 goes into 2280 3 times with a remainder of 558.
Write down 3 as next digit of the result. 
Result so far: 29299.83
The remainder is 558 after subtracting 1722 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 11:
574 can be fit into 5580 9 times, resulting in a remainder of 414.
The number 9 becomes the next digit in our result. 
Result so far: 29299.839
The remainder is 414 after subtracting 5166 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 12:
The number 574 fits into 4140 7 times, leaving a remainder of 122.
Put 7 as the next digit of the answer. 
Result so far: 29299.8397
The remainder is 122 after subtracting 4018 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 13:
574 can be fit into 1220 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 29299.83972
Subtract 1148 from 1220 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
574 can be fit into 720 1 times, resulting in a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 29299.839721
Subtracting 574 from 720 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 15:
When dividing 1460 by 574, we get 2 with a remainder of 312.
Record the quotient 2 as the next digit in the result. 
Result so far: 29299.8397212
The remainder is 312 after subtracting 1148 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 16:
574 can be fit into 3120 5 times, resulting in a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 29299.83972125
Deduct 2870 from 3120 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The quotient of the division is 29299.83972125, and the remainder is 2.5e-07.
