Let's divide 45944929 by 91
The aim is to understand the frequency of 91 in 45944929.

Step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 91

Step 2:
91 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 91

Let's proceed to step 3:
If we divide 459 by 91, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 455 from 459, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 91

On to step 4:
91 can be fit into 44 0 times, resulting in a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 44 leaves us with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 91

Let's proceed to step 5:
444 divided by 91 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 504.0
Subtracting 364 from 444 leaves us with 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 91

Moving on to step 6:
If we divide 809 by 91, we get 8 and a remainder of 81.
Use 8 as the next digit of our solution. 
Result so far: 5048.0
If we take 728 away from 809, we end up with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 91

Moving on to step 7:
The number 91 fits into 812 8 times, leaving a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 50488.0
Subtract 728 from 812 to get 84.
Take the next digit (9) from the dividend and append it to 84, then repeat: 849 / 91

Going ahead to step 8:
The number 91 fits into 849 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 504889.0
Subtracting 819 from 849 leaves us 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 9:
300 divided by 91 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 504889.3
Subtract 273 from 300 to 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.

On to step 10:
If we divide 270 by 91, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 504889.32
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.

Let's proceed to step 11:
91 can be fit into 880 9 times, resulting in a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 504889.329
If we take 819 away from 880, we end up 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.

Going ahead to step 12:
91 can be fit into 610 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 504889.3296
If we take 546 away from 610, we end up 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.

On to step 13:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 504889.32967
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.

Going ahead to step 14:
30 divided by 91 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 504889.32967
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.

On to step 15:
When dividing 300 by 91, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 504889.3296703
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 16:
If we divide 270 by 91, we get 2 and a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 504889.32967032
If we take 182 away from 270, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 504889.32967032 and a remainder of 8.8e-08.
