We divide 687076 by 91
The aim is to understand the frequency of 91 in 687076.

Moving on to step 1:
If we divide 6 by 91, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 91

Let's proceed to step 2:
If we divide 68 by 91, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 91

Advancing to step 3:
When dividing 687 by 91, we get 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 637 away from 687, we end up with 50.
Take the next digit (0) from the dividend and append it to 50, then repeat: 500 / 91

Let's proceed to step 4:
When dividing 500 by 91, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 45 after subtracting 455 from 500.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 91

Step 5:
When dividing 457 by 91, we get 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 755.0
If we subtract 455 from 457, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 91

Let's proceed to step 6:
If we divide 26 by 91, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 7550.0
If we take 0 away from 26, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 91 is 2 with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 7550.2
Subtracting 182 from 260 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
91 goes into 780 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 7550.28
If we subtract 728 from 780, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
The number 91 fits into 520 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 7550.285
If we take 455 away from 520, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
91 can be fit into 650 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7550.2857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
91 goes into 130 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 7550.28571
Subtracting 91 from 130 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
91 goes into 390 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7550.285714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
The number 91 fits into 260 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 7550.2857142
If we take 182 away from 260, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 14:
91 goes into 780 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 7550.28571428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 7550.28571428 with a balance of 5.2e-08.
