45391466 ÷ 915 
The aim is to understand the frequency of 915 in 45391466.

Advancing to step 1:
4 divided by 915 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 915

Let's proceed to step 2:
915 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 915

Let's proceed to step 3:
453 divided by 915 is 0 with a remainder of 453.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 453, we end up with 453.
Fetch the next digit (9) from the dividend, attach it to 453 and continue: 4539 / 915

On to step 4:
915 can be fit into 4539 4 times, resulting in a remainder of 879.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3660 from 4539 and we're left with 879.
Grab the next digit (1) from the dividend, add it to 879, then carry on: 8791 / 915

Advancing to step 5:
915 can be fit into 8791 9 times, resulting in a remainder of 556.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 556 after subtracting 8235 from 8791.
Bring next digit (4) of the dividend behind the 556 and repeat the process: 5564 / 915

On to step 6:
5564 divided by 915 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 496.0
Subtract 5490 from 5564 to get 74.
Grab the next digit (6) from the dividend, add it to 74, then carry on: 746 / 915

On to step 7:
When dividing 746 by 915, we get 0 with a remainder of 746.
Record the quotient 0 as the next digit in the result. 
Result so far: 4960.0
Subtract 0 from 746 to get 746.
Append the next digit (6) from the dividend to 746 and continue with: 7466 / 915

Let's proceed to step 8:
7466 divided by 915 is 8 with a remainder of 146.
The number 8 becomes the next digit in our result. 
Result so far: 49608.0
If we subtract 7320 from 7466, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
1460 divided by 915 is 1 with a remainder of 545.
Put 1 as the next digit of the answer. 
Result so far: 49608.1
The remainder is 545 after subtracting 915 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 10:
If we divide 5450 by 915, we get 5 and a remainder of 875.
The number 5 becomes the next digit in our result. 
Result so far: 49608.15
If we take 4575 away from 5450, we end up with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

On to step 11:
The number 915 fits into 8750 9 times, leaving a remainder of 515.
Write down 9 as next digit of the result. 
Result so far: 49608.159
If we subtract 8235 from 8750, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 12:
915 goes into 5150 5 times with a remainder of 575.
The number 5 becomes the next digit in our result. 
Result so far: 49608.1595
If we take 4575 away from 5150, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 13:
The number 915 fits into 5750 6 times, leaving a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 49608.15956
Subtract 5490 from 5750 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
2600 divided by 915 is 2 with a remainder of 770.
The number 2 becomes the next digit in our result. 
Result so far: 49608.159562
If we take 1830 away from 2600, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 15:
If we divide 7700 by 915, we get 8 and a remainder of 380.
Use 8 as the next digit of our solution. 
Result so far: 49608.1595628
Subtract 7320 from 7700 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
When dividing 3800 by 915, we get 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 49608.15956284
Subtracting 3660 from 3800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 49608.15956284, with a leftover of 1.4e-07.
