84357099 ÷ 571 
The aim is to understand the frequency of 571 in 84357099.

Moving on to step 1:
571 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 571

Let's proceed to step 2:
84 divided by 571 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 571

Let's proceed to step 3:
843 divided by 571 is 1 with a remainder of 272.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 571 from 843 leaves us with 272.
Fetch the next digit (5) from the dividend, attach it to 272 and continue: 2725 / 571

Step 4:
2725 divided by 571 is 4 with a remainder of 441.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2284 from 2725 and we're left with 441.
Grab the next digit (7) from the dividend, add it to 441, then carry on: 4417 / 571

On to step 5:
571 goes into 4417 7 times with a remainder of 420.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Deduct 3997 from 4417 and we're left with 420.
Bring next digit (0) of the dividend behind the 420 and repeat the process: 4200 / 571

Step 6:
When dividing 4200 by 571, we get 7 with a remainder of 203.
Record the quotient 7 as the next digit in the result. 
Result so far: 1477.0
The remainder is 203 after subtracting 3997 from 4200.
Append the next digit (9) from the dividend to 203 and continue with: 2039 / 571

On to step 7:
2039 divided by 571 is 3 with a remainder of 326.
Write down 3 as next digit of the result. 
Result so far: 14773.0
Subtract 1713 from 2039 to get 326.
Bring next digit (9) of the dividend behind the 326 and repeat the process: 3269 / 571

Going ahead to step 8:
571 goes into 3269 5 times with a remainder of 414.
Record the quotient 5 as the next digit in the result. 
Result so far: 147735.0
The remainder is 414 after subtracting 2855 from 3269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 9:
When dividing 4140 by 571, we get 7 with a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 147735.7
The remainder is 143 after subtracting 3997 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 10:
1430 divided by 571 is 2 with a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 147735.72
The remainder is 288 after subtracting 1142 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 11:
2880 divided by 571 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 147735.725
Deduct 2855 from 2880 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
571 goes into 250 0 times with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 147735.725
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
2500 divided by 571 is 4 with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 147735.72504
Deduct 2284 from 2500 and we're left with 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 14:
When dividing 2160 by 571, we get 3 with a remainder of 447.
The number 3 becomes the next digit in our result. 
Result so far: 147735.725043
If we take 1713 away from 2160, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 15:
4470 divided by 571 is 7 with a remainder of 473.
Put 7 as the next digit of the answer. 
Result so far: 147735.7250437
Deduct 3997 from 4470 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 16:
When dividing 4730 by 571, we get 8 with a remainder of 162.
Record the quotient 8 as the next digit in the result. 
Result so far: 147735.72504378
If we take 4568 away from 4730, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 147735.72504378, with a leftover of 1.62e-07.
