18640100 divided by 574 
The aim is to understand the frequency of 574 in 18640100.

Step 1:
1 divided by 574 is 0 with 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.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 574

Going ahead to step 2:
18 divided by 574 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 574

Advancing to step 3:
When dividing 186 by 574, we get 0 with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Take the next digit (4) from the dividend and append it to 186, then repeat: 1864 / 574

Step 4:
574 can be fit into 1864 3 times, resulting in a remainder of 142.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1722 away from 1864, we end up with 142.
Append the next digit (0) from the dividend to 142 and continue with: 1420 / 574

Let's proceed to step 5:
1420 divided by 574 is 2 with a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we take 1148 away from 1420, we end up with 272.
Include the next digit (1) from the dividend after 272, then repeat: 2721 / 574

Going ahead to step 6:
574 can be fit into 2721 4 times, resulting in a remainder of 425.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
If we take 2296 away from 2721, we end up with 425.
Fetch the next digit (0) from the dividend, attach it to 425 and continue: 4250 / 574

Advancing to step 7:
The number 574 fits into 4250 7 times, leaving a remainder of 232.
Use 7 as the next digit of our solution. 
Result so far: 3247.0
The remainder is 232 after subtracting 4018 from 4250.
Fetch the next digit (0) from the dividend, attach it to 232 and continue: 2320 / 574

Moving on to step 8:
If we divide 2320 by 574, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 32474.0
Deduct 2296 from 2320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
574 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 32474.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
The number 574 fits into 2400 4 times, leaving a remainder of 104.
The next digit of our result is 4. 
Result so far: 32474.04
Subtracting 2296 from 2400 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
If we divide 1040 by 574, we get 1 and a remainder of 466.
Write down 1 as next digit of the result. 
Result so far: 32474.041
Deduct 574 from 1040 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 12:
574 goes into 4660 8 times with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 32474.0418
If we take 4592 away from 4660, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
574 goes into 680 1 times with a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 32474.04181
If we subtract 574 from 680, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 14:
If we divide 1060 by 574, we get 1 and a remainder of 486.
Record the quotient 1 as the next digit in the result. 
Result so far: 32474.041811
Deduct 574 from 1060 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

The final result is 32474.041811 with a remainder of 4.86e-05.
