37459 ÷ 91 
The aim is to understand the frequency of 91 in 37459.

Advancing to step 1:
If we divide 3 by 91, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 91

Let's proceed to step 2:
When dividing 37 by 91, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 91

Going ahead to step 3:
The number 91 fits into 374 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 364 from 374 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 91

Step 4:
When dividing 105 by 91, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 14 after subtracting 91 from 105.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 91

Moving on to step 5:
When dividing 149 by 91, we get 1 with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
Subtracting 91 from 149 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 6:
91 goes into 580 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 411.6
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
When dividing 340 by 91, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 411.63
The remainder is 67 after subtracting 273 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
670 divided by 91 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 411.637
If we take 637 away from 670, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
The number 91 fits into 330 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 411.6373
The remainder is 57 after subtracting 273 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
If we divide 570 by 91, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 411.63736
If we take 546 away from 570, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 91, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 411.637362
Subtract 182 from 240 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
When dividing 580 by 91, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 411.6373626
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
If we divide 340 by 91, we get 3 and a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 411.63736263
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 411.63736263, and the remainder is 6.7e-08.
