We divide 840260 by 91
The aim is to understand the frequency of 91 in 840260.

Step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 91

Let's proceed to step 2:
91 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 91

Advancing to step 3:
91 goes into 840 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 819 from 840 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 91

Moving on to step 4:
212 divided by 91 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtract 182 from 212 to get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 91

Moving on to step 5:
The number 91 fits into 306 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 923.0
Deduct 273 from 306 and we're left with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 91

On to step 6:
When dividing 330 by 91, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 9233.0
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
570 divided by 91 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 9233.6
If we subtract 546 from 570, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
91 goes into 240 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 9233.62
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
91 goes into 580 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 9233.626
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
When dividing 340 by 91, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 9233.6263
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
91 can be fit into 670 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 9233.62637
The remainder is 33 after subtracting 637 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 12:
If we divide 330 by 91, we get 3 and a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 9233.626373
Subtracting 273 from 330 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 13:
When dividing 570 by 91, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 9233.6263736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
91 goes into 240 2 times with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 9233.62637362
If we take 182 away from 240, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 9233.62637362, and the remainder is 5.8e-08.
