We look at the division of 18910456 by 572 
The aim is to understand the frequency of 572 in 18910456.

Advancing to step 1:
When dividing 1 by 572, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 572

Advancing to step 2:
When dividing 18 by 572, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 572

Let's proceed to step 3:
If we divide 189 by 572, we get 0 and a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 189, we get 189.
Grab the next digit (1) from the dividend, add it to 189, then carry on: 1891 / 572

Let's proceed to step 4:
1891 divided by 572 is 3 with a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1716 from 1891 leaves us with 175.
Fetch the next digit (0) from the dividend, attach it to 175 and continue: 1750 / 572

Let's proceed to step 5:
When dividing 1750 by 572, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 34 after subtracting 1716 from 1750.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 572

Step 6:
572 goes into 344 0 times with a remainder of 344.
Put 0 as the next digit of the answer. 
Result so far: 330.0
Subtract 0 from 344 to get 344.
Bring next digit (5) of the dividend behind the 344 and repeat the process: 3445 / 572

On to step 7:
572 goes into 3445 6 times with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 3306.0
The remainder is 13 after subtracting 3432 from 3445.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 572

Going ahead to step 8:
If we divide 136 by 572, we get 0 and a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 33060.0
Subtracting 0 from 136 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 9:
If we divide 1360 by 572, we get 2 and a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 33060.2
Subtract 1144 from 1360 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
572 goes into 2160 3 times with a remainder of 444.
Record the quotient 3 as the next digit in the result. 
Result so far: 33060.23
If we take 1716 away from 2160, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 11:
4440 divided by 572 is 7 with a remainder of 436.
Put 7 as the next digit of the answer. 
Result so far: 33060.237
Subtract 4004 from 4440 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 12:
572 goes into 4360 7 times with a remainder of 356.
Record the quotient 7 as the next digit in the result. 
Result so far: 33060.2377
If we take 4004 away from 4360, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Our division results in 33060.2377 with a remaining 0.00356.
