We divide 977116 by 91
The aim is to understand the frequency of 91 in 977116.

Advancing to step 1:
91 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 91

Step 2:
The number 91 fits into 97 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 91 away from 97, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 91

Moving on to step 3:
The number 91 fits into 67 0 times, leaving a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 67 after subtracting 0 from 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 91

Going ahead to step 4:
When dividing 671 by 91, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 637 from 671 and we're left with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 91

Step 5:
The number 91 fits into 341 3 times, leaving a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
The remainder is 68 after subtracting 273 from 341.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 91

On to step 6:
The number 91 fits into 686 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 10737.0
If we subtract 637 from 686, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
If we divide 490 by 91, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 10737.5
The remainder is 35 after subtracting 455 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
If we divide 350 by 91, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 10737.53
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
If we divide 770 by 91, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 10737.538
Subtract 728 from 770 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
420 divided by 91 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 10737.5384
The remainder is 56 after subtracting 364 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
The number 91 fits into 560 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 10737.53846
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
The number 91 fits into 140 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 10737.538461
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 13:
When dividing 490 by 91, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 10737.5384615
If we subtract 455 from 490, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
The number 91 fits into 350 3 times, leaving a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 10737.53846153
Subtract 273 from 350 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Our division results in 10737.53846153 with a remaining 7.7e-08.
