Let's divide 984854 by 91
The aim is to understand the frequency of 91 in 984854.

Going ahead to step 1:
9 divided by 91 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 91

Going ahead to step 2:
91 can be fit into 98 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 91 from 98 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 91

On to step 3:
91 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 74 after subtracting 0 from 74.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 91

Let's proceed to step 4:
91 goes into 748 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 728 from 748 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 91

Step 5:
91 can be fit into 205 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 1082.0
The remainder is 23 after subtracting 182 from 205.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 91

Advancing to step 6:
234 divided by 91 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 10822.0
Subtracting 182 from 234 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
91 goes into 520 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 10822.5
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.

Let's proceed to step 8:
91 goes into 650 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 10822.57
Subtracting 637 from 650 leaves us 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.

Step 9:
When dividing 130 by 91, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 10822.571
If we take 91 away from 130, we end up 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.

On to step 10:
91 can be fit into 390 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 10822.5714
Deduct 364 from 390 and we're left 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.

On to step 11:
91 goes into 260 2 times with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 10822.57142
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.

Let's proceed to step 12:
When dividing 780 by 91, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 10822.571428
Deduct 728 from 780 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
If we divide 520 by 91, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 10822.5714285
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.

Let's proceed to step 14:
If we divide 650 by 91, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 10822.57142857
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.

After the division, we end up with 10822.57142857 and a remainder of 1.3e-08.
