344150 ÷ 91 
The aim is to understand the frequency of 91 in 344150.

Moving on to step 1:
If we divide 3 by 91, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 91

Advancing to step 2:
The number 91 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 91

Moving on to step 3:
344 divided by 91 is 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 273 away from 344, we end up with 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 91

Let's proceed to step 4:
When dividing 711 by 91, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 37.0
If we take 637 away from 711, we end up with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 91

On to step 5:
The number 91 fits into 745 8 times, leaving a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
The remainder is 17 after subtracting 728 from 745.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 91

Moving on to step 6:
The number 91 fits into 170 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 3781.0
Deduct 91 from 170 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
When dividing 790 by 91, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 3781.8
If we subtract 728 from 790, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
When dividing 620 by 91, we get 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 3781.86
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
91 can be fit into 740 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3781.868
Deduct 728 from 740 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
When dividing 120 by 91, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 3781.8681
The remainder is 29 after subtracting 91 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
When dividing 290 by 91, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3781.86813
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
When dividing 170 by 91, we get 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 3781.868131
The remainder is 79 after subtracting 91 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 13:
91 can be fit into 790 8 times, resulting in a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 3781.8681318
The remainder is 62 after subtracting 728 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
620 divided by 91 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 3781.86813186
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 3781.86813186, and the remainder is 7.4e-08.
