We divide 570842 by 91
The aim is to understand the frequency of 91 in 570842.

Moving on to step 1:
The number 91 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 91

Moving on to step 2:
91 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 91

Let's proceed to step 3:
91 can be fit into 570 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 6.0
If we take 546 away from 570, we end up with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 91

Moving on to step 4:
When dividing 248 by 91, we get 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 182 away from 248, we end up with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 91

Advancing to step 5:
91 can be fit into 664 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 627.0
If we subtract 637 from 664, we get 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 91

Going ahead to step 6:
The number 91 fits into 272 2 times, leaving a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 6272.0
The remainder is 90 after subtracting 182 from 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 7:
91 goes into 900 9 times with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 6272.9
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 8:
810 divided by 91 is 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 6272.98
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
If we divide 820 by 91, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6272.989
Deduct 819 from 820 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
When dividing 10 by 91, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6272.989
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
91 goes into 100 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 6272.98901
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
When dividing 90 by 91, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 6272.98901
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
91 goes into 900 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 6272.9890109
If we take 819 away from 900, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 14:
810 divided by 91 is 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 6272.98901098
Subtract 728 from 810 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final result is 6272.98901098 with a remainder of 8.2e-08.
