571656 ÷ 91 
The aim is to understand the frequency of 91 in 571656.

Let's proceed to step 1:
The number 91 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 91

Advancing to step 2:
If we divide 57 by 91, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 91

Let's proceed to step 3:
If we divide 571 by 91, we get 6 and a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 546 from 571 and we're left with 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 91

Step 4:
91 goes into 256 2 times with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we take 182 away from 256, we end up with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 91

Going ahead to step 5:
745 divided by 91 is 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 628.0
The remainder is 17 after subtracting 728 from 745.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 91

Let's proceed to step 6:
176 divided by 91 is 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 6281.0
If we subtract 91 from 176, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
When dividing 850 by 91, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 6281.9
Subtracting 819 from 850 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
91 can be fit into 310 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 6281.93
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
370 divided by 91 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 6281.934
Subtracting 364 from 370 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 91, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 6281.934
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
600 divided by 91 is 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 6281.93406
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
If we divide 540 by 91, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 6281.934065
Deduct 455 from 540 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 6281.9340659
If we take 819 away from 850, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
91 can be fit into 310 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 6281.93406593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 6281.93406593, and the remainder is 3.7e-08.
