Let's divide 841289 by 91
The aim is to understand the frequency of 91 in 841289.

Step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 91

Let's proceed to step 2:
84 divided by 91 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 91

Step 3:
When dividing 841 by 91, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 819 away from 841, we end up with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 91

Let's proceed to step 4:
222 divided by 91 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtract 182 from 222 to get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 91

Step 5:
91 can be fit into 408 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 924.0
Deduct 364 from 408 and we're left with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 91

Advancing to step 6:
449 divided by 91 is 4 with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 9244.0
Deduct 364 from 449 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
91 goes into 850 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 9244.9
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
The number 91 fits into 310 3 times, leaving a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 9244.93
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
When dividing 370 by 91, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 9244.934
Deduct 364 from 370 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
If we divide 60 by 91, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9244.934
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 91, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 9244.93406
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
When dividing 540 by 91, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 9244.934065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
The number 91 fits into 850 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 9244.9340659
If we take 819 away from 850, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
The number 91 fits into 310 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 9244.93406593
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 9244.93406593 and a remainder of 3.7e-08.
