19804920 ÷ 571 
The aim is to understand the frequency of 571 in 19804920.

Moving on to step 1:
571 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 571

Going ahead to step 2:
When dividing 19 by 571, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 571

Going ahead to step 3:
When dividing 198 by 571, we get 0 with a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Bring next digit (0) of the dividend behind the 198 and repeat the process: 1980 / 571

Moving on to step 4:
571 can be fit into 1980 3 times, resulting in a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1713 from 1980 and we're left with 267.
Grab the next digit (4) from the dividend, add it to 267, then carry on: 2674 / 571

Advancing to step 5:
The number 571 fits into 2674 4 times, leaving a remainder of 390.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 2284 from 2674 leaves us with 390.
Include the next digit (9) from the dividend after 390, then repeat: 3909 / 571

Going ahead to step 6:
571 goes into 3909 6 times with a remainder of 483.
The next digit of our result is 6. 
Result so far: 346.0
If we subtract 3426 from 3909, we get 483.
Grab the next digit (2) from the dividend, add it to 483, then carry on: 4832 / 571

Step 7:
The number 571 fits into 4832 8 times, leaving a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 3468.0
If we subtract 4568 from 4832, we get 264.
Take the next digit (0) from the dividend and append it to 264, then repeat: 2640 / 571

Step 8:
The number 571 fits into 2640 4 times, leaving a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 34684.0
If we take 2284 away from 2640, 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.

Advancing to step 9:
3560 divided by 571 is 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 34684.6
Deduct 3426 from 3560 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
The number 571 fits into 1340 2 times, leaving a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 34684.62
Subtract 1142 from 1340 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 11:
If we divide 1980 by 571, we get 3 and a remainder of 267.
The number 3 becomes the next digit in our result. 
Result so far: 34684.623
The remainder is 267 after subtracting 1713 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 12:
The number 571 fits into 2670 4 times, leaving a remainder of 386.
Use 4 as the next digit of our solution. 
Result so far: 34684.6234
Deduct 2284 from 2670 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 13:
571 goes into 3860 6 times with a remainder of 434.
Record the quotient 6 as the next digit in the result. 
Result so far: 34684.62346
Deduct 3426 from 3860 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 14:
4340 divided by 571 is 7 with a remainder of 343.
The number 7 becomes the next digit in our result. 
Result so far: 34684.623467
Subtract 3997 from 4340 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 15:
The number 571 fits into 3430 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 34684.6234676
The remainder is 4 after subtracting 3426 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 16:
571 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 34684.6234676
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 34684.6234676 with a remaining 4e-08.
