We divide 908141 by 91
The aim is to understand the frequency of 91 in 908141.

On to step 1:
91 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 91

Moving on to step 2:
91 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 91

Advancing to step 3:
The number 91 fits into 908 9 times, leaving a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 819 from 908 to get 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 91

Going ahead to step 4:
891 divided by 91 is 9 with a remainder of 72.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 72 after subtracting 819 from 891.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 91

Advancing to step 5:
91 can be fit into 724 7 times, resulting in a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 997.0
If we subtract 637 from 724, we get 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 91

Step 6:
The number 91 fits into 871 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 9979.0
The remainder is 52 after subtracting 819 from 871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
91 goes into 520 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 9979.5
Subtract 455 from 520 to get 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 8:
The number 91 fits into 650 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9979.57
Deduct 637 from 650 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 91, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 9979.571
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
91 can be fit into 390 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 9979.5714
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
91 can be fit into 260 2 times, resulting in a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 9979.57142
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.

Moving on to step 12:
The number 91 fits into 780 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 9979.571428
Subtract 728 from 780 to 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.

On to step 13:
520 divided by 91 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 9979.5714285
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.

Advancing to step 14:
The number 91 fits into 650 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 9979.57142857
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 9979.57142857, and the remainder is 1.3e-08.
