We divide 53028252 by 91
The aim is to understand the frequency of 91 in 53028252.

Step 1:
If we divide 5 by 91, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 91

Let's proceed to step 2:
If we divide 53 by 91, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 91

Going ahead to step 3:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 455 from 530, we get 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 91

Step 4:
The number 91 fits into 752 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
The remainder is 24 after subtracting 728 from 752.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 91

Let's proceed to step 5:
The number 91 fits into 248 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 582.0
If we subtract 182 from 248, we get 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 91

Let's proceed to step 6:
662 divided by 91 is 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 5827.0
Subtract 637 from 662 to get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 91

Moving on to step 7:
If we divide 255 by 91, we get 2 and a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 58272.0
If we take 182 away from 255, we end up with 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 91

Moving on to step 8:
91 goes into 732 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 582728.0
The remainder is 4 after subtracting 728 from 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 91, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 582728.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 91 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 582728.04
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 582728.043
Deduct 273 from 360 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 12:
91 goes into 870 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 582728.0439
The remainder is 51 after subtracting 819 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 13:
91 goes into 510 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 582728.04395
The remainder is 55 after subtracting 455 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
91 goes into 550 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 582728.043956
If we take 546 away from 550, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 15:
91 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 582728.043956
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
91 can be fit into 400 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 582728.04395604
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 582728.04395604, with a leftover of 3.6e-08.
