We divide 457157 by 91
The aim is to understand the frequency of 91 in 457157.

Let's proceed to step 1:
4 divided by 91 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 91

Moving on to step 2:
91 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 91

Step 3:
If we divide 457 by 91, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 455 away from 457, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 91

Advancing to step 4:
91 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 91

Going ahead to step 5:
If we divide 215 by 91, we get 2 and a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 502.0
Deduct 182 from 215 and we're left with 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 91

Going ahead to step 6:
When dividing 337 by 91, we get 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 5023.0
Subtracting 273 from 337 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
91 goes into 640 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 5023.7
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
30 divided by 91 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5023.7
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
91 goes into 300 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 5023.703
If we subtract 273 from 300, we get 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 10:
91 can be fit into 270 2 times, resulting in a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 5023.7032
If we subtract 182 from 270, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
880 divided by 91 is 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 5023.70329
Subtracting 819 from 880 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
91 goes into 610 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 5023.703296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
91 can be fit into 640 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 5023.7032967
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
If we divide 30 by 91, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 5023.7032967
If we take 0 away from 30, we end up 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.

In conclusion, the division gives 5023.7032967 with a balance of 3e-08.
