We divide 785258 by 91
The aim is to understand the frequency of 91 in 785258.

Let's proceed to step 1:
The number 91 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 91

On to step 2:
The number 91 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 91

Going ahead to step 3:
If we divide 785 by 91, we get 8 and a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 728 from 785 to get 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 91

Advancing to step 4:
91 can be fit into 572 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtract 546 from 572 to get 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 91

Going ahead to step 5:
If we divide 265 by 91, we get 2 and a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 862.0
If we take 182 away from 265, we end up with 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 91

Let's proceed to step 6:
The number 91 fits into 838 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 8629.0
If we subtract 819 from 838, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 91, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8629.2
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
91 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 8629.2
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
When dividing 800 by 91, we get 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 8629.208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
If we divide 720 by 91, we get 7 and a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 8629.2087
Subtract 637 from 720 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 11:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 8629.20879
The remainder is 11 after subtracting 819 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
91 goes into 110 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8629.208791
Deduct 91 from 110 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
If we divide 190 by 91, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8629.2087912
Subtract 182 from 190 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
When dividing 80 by 91, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 8629.2087912
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 8629.2087912, and the remainder is 8e-08.
