We divide 420241 by 91
The aim is to understand the frequency of 91 in 420241.

Advancing to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 91

Advancing to step 2:
If we divide 42 by 91, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 91

Advancing to step 3:
91 can be fit into 420 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 364 from 420 to get 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 91

Moving on to step 4:
91 goes into 562 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 546 from 562 leaves us with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 91

Let's proceed to step 5:
91 can be fit into 164 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 461.0
Deduct 91 from 164 and we're left with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 91

Going ahead to step 6:
The number 91 fits into 731 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 4618.0
Subtracting 728 from 731 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
91 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4618.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 91 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 4618.03
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
When dividing 270 by 91, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 4618.032
The remainder is 88 after subtracting 182 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
When dividing 880 by 91, we get 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 4618.0329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 11:
The number 91 fits into 610 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 4618.03296
The remainder is 64 after subtracting 546 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
91 goes into 640 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 4618.032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
If we divide 30 by 91, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4618.032967
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
91 goes into 300 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 4618.03296703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 4618.03296703 with a remaining 2.7e-08.
