We divide 85017349 by 571
The aim is to understand the frequency of 571 in 85017349.

Moving on to step 1:
When dividing 8 by 571, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 571

Moving on to step 2:
85 divided by 571 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 571

Advancing to step 3:
571 can be fit into 850 1 times, resulting in a remainder of 279.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 571 from 850 and we're left with 279.
Grab the next digit (1) from the dividend, add it to 279, then carry on: 2791 / 571

On to step 4:
2791 divided by 571 is 4 with a remainder of 507.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2284 from 2791, we get 507.
Append the next digit (7) from the dividend to 507 and continue with: 5077 / 571

Moving on to step 5:
571 can be fit into 5077 8 times, resulting in a remainder of 509.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Deduct 4568 from 5077 and we're left with 509.
Append the next digit (3) from the dividend to 509 and continue with: 5093 / 571

Advancing to step 6:
When dividing 5093 by 571, we get 8 with a remainder of 525.
The number 8 becomes the next digit in our result. 
Result so far: 1488.0
If we subtract 4568 from 5093, we get 525.
Fetch the next digit (4) from the dividend, attach it to 525 and continue: 5254 / 571

Moving on to step 7:
571 can be fit into 5254 9 times, resulting in a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 14889.0
If we subtract 5139 from 5254, we get 115.
Include the next digit (9) from the dividend after 115, then repeat: 1159 / 571

Let's proceed to step 8:
1159 divided by 571 is 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 148892.0
The remainder is 17 after subtracting 1142 from 1159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
If we divide 170 by 571, we get 0 and a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 148892.0
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
The number 571 fits into 1700 2 times, leaving a remainder of 558.
The next digit of our result is 2. 
Result so far: 148892.02
Deduct 1142 from 1700 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 11:
If we divide 5580 by 571, we get 9 and a remainder of 441.
Put 9 as the next digit of the answer. 
Result so far: 148892.029
Deduct 5139 from 5580 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 12:
When dividing 4410 by 571, we get 7 with a remainder of 413.
Write down 7 as next digit of the result. 
Result so far: 148892.0297
If we subtract 3997 from 4410, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 13:
The number 571 fits into 4130 7 times, leaving a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 148892.02977
Subtracting 3997 from 4130 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The quotient of the division is 148892.02977, and the remainder is 0.000133.
