80749407 ÷ 571 
The aim is to understand the frequency of 571 in 80749407.

Advancing to step 1:
8 divided by 571 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 571

Going ahead to step 2:
80 divided by 571 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 571

Moving on to step 3:
When dividing 807 by 571, we get 1 with a remainder of 236.
The next digit of our result is 1. 
Result so far: 1.0
If we take 571 away from 807, we end up with 236.
Include the next digit (4) from the dividend after 236, then repeat: 2364 / 571

Step 4:
2364 divided by 571 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 80 after subtracting 2284 from 2364.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 571

Let's proceed to step 5:
If we divide 809 by 571, we get 1 and a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtracting 571 from 809 leaves us with 238.
Bring next digit (4) of the dividend behind the 238 and repeat the process: 2384 / 571

On to step 6:
2384 divided by 571 is 4 with a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
The remainder is 100 after subtracting 2284 from 2384.
Take the next digit (0) from the dividend and append it to 100, then repeat: 1000 / 571

Moving on to step 7:
If we divide 1000 by 571, we get 1 and a remainder of 429.
Record the quotient 1 as the next digit in the result. 
Result so far: 14141.0
Subtract 571 from 1000 to get 429.
Append the next digit (7) from the dividend to 429 and continue with: 4297 / 571

Let's proceed to step 8:
If we divide 4297 by 571, we get 7 and a remainder of 300.
The number 7 becomes the next digit in our result. 
Result so far: 141417.0
The remainder is 300 after subtracting 3997 from 4297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 9:
The number 571 fits into 3000 5 times, leaving a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 141417.5
If we subtract 2855 from 3000, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
571 can be fit into 1450 2 times, resulting in a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 141417.52
Subtracting 1142 from 1450 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 11:
If we divide 3080 by 571, we get 5 and a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 141417.525
The remainder is 225 after subtracting 2855 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 12:
When dividing 2250 by 571, we get 3 with a remainder of 537.
Record the quotient 3 as the next digit in the result. 
Result so far: 141417.5253
The remainder is 537 after subtracting 1713 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Let's proceed to step 13:
5370 divided by 571 is 9 with a remainder of 231.
Record the quotient 9 as the next digit in the result. 
Result so far: 141417.52539
The remainder is 231 after subtracting 5139 from 5370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 14:
2310 divided by 571 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 141417.525394
Deduct 2284 from 2310 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 15:
571 goes into 260 0 times with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 141417.525394
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 16:
If we divide 2600 by 571, we get 4 and a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 141417.52539404
Subtract 2284 from 2600 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Our division results in 141417.52539404 with a remaining 3.16e-07.
