We look at the division of 19611899 by 576 
The aim is to understand the frequency of 576 in 19611899.

On to step 1:
When dividing 1 by 576, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 576

Moving on to step 2:
576 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 576

Moving on to step 3:
196 divided by 576 is 0 with a remainder of 196.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Include the next digit (1) from the dividend after 196, then repeat: 1961 / 576

Let's proceed to step 4:
The number 576 fits into 1961 3 times, leaving a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 233 after subtracting 1728 from 1961.
Include the next digit (1) from the dividend after 233, then repeat: 2331 / 576

Let's proceed to step 5:
If we divide 2331 by 576, we get 4 and a remainder of 27.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 2304 from 2331, we get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 576

Moving on to step 6:
278 divided by 576 is 0 with a remainder of 278.
Use 0 as the next digit of our solution. 
Result so far: 340.0
Subtracting 0 from 278 leaves us with 278.
Grab the next digit (9) from the dividend, add it to 278, then carry on: 2789 / 576

On to step 7:
When dividing 2789 by 576, we get 4 with a remainder of 485.
Write down 4 as next digit of the result. 
Result so far: 3404.0
If we take 2304 away from 2789, we end up with 485.
Bring next digit (9) of the dividend behind the 485 and repeat the process: 4859 / 576

Going ahead to step 8:
576 goes into 4859 8 times with a remainder of 251.
The number 8 becomes the next digit in our result. 
Result so far: 34048.0
If we take 4608 away from 4859, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 9:
2510 divided by 576 is 4 with a remainder of 206.
The number 4 becomes the next digit in our result. 
Result so far: 34048.4
If we take 2304 away from 2510, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 10:
When dividing 2060 by 576, we get 3 with a remainder of 332.
Use 3 as the next digit of our solution. 
Result so far: 34048.43
Subtract 1728 from 2060 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
576 goes into 3320 5 times with a remainder of 440.
The number 5 becomes the next digit in our result. 
Result so far: 34048.435
Deduct 2880 from 3320 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
4400 divided by 576 is 7 with a remainder of 368.
The next digit of our result is 7. 
Result so far: 34048.4357
Deduct 4032 from 4400 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 13:
If we divide 3680 by 576, we get 6 and a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 34048.43576
Subtracting 3456 from 3680 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
2240 divided by 576 is 3 with a remainder of 512.
The next digit of our result is 3. 
Result so far: 34048.435763
The remainder is 512 after subtracting 1728 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 15:
576 goes into 5120 8 times with a remainder of 512.
Write down 8 as next digit of the result. 
Result so far: 34048.4357638
If we take 4608 away from 5120, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 16:
576 can be fit into 5120 8 times, resulting in a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 34048.43576388
Deduct 4608 from 5120 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

After the division, we end up with 34048.43576388 and a remainder of 5.12e-07.
