We're dividing 1520381 by 916 
The aim is to understand the frequency of 916 in 1520381.

Going ahead to step 1:
1 divided by 916 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 916

On to step 2:
916 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 916

On to step 3:
When dividing 152 by 916, we get 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 152 to get 152.
Append the next digit (0) from the dividend to 152 and continue with: 1520 / 916

Step 4:
916 goes into 1520 1 times with a remainder of 604.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 916 from 1520, we get 604.
Take the next digit (3) from the dividend and append it to 604, then repeat: 6043 / 916

Step 5:
When dividing 6043 by 916, we get 6 with a remainder of 547.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 5496 away from 6043, we end up with 547.
Include the next digit (8) from the dividend after 547, then repeat: 5478 / 916

Moving on to step 6:
916 can be fit into 5478 5 times, resulting in a remainder of 898.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Subtracting 4580 from 5478 leaves us with 898.
Take the next digit (1) from the dividend and append it to 898, then repeat: 8981 / 916

Moving on to step 7:
916 goes into 8981 9 times with a remainder of 737.
The number 9 becomes the next digit in our result. 
Result so far: 1659.0
Subtract 8244 from 8981 to get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 8:
The number 916 fits into 7370 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 1659.8
If we subtract 7328 from 7370, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
When dividing 420 by 916, we get 0 with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 1659.8
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 10:
The number 916 fits into 4200 4 times, leaving a remainder of 536.
The number 4 becomes the next digit in our result. 
Result so far: 1659.804
Subtracting 3664 from 4200 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 11:
916 goes into 5360 5 times with a remainder of 780.
Put 5 as the next digit of the answer. 
Result so far: 1659.8045
Subtracting 4580 from 5360 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 12:
916 can be fit into 7800 8 times, resulting in a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 1659.80458
Deduct 7328 from 7800 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 13:
916 can be fit into 4720 5 times, resulting in a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 1659.804585
If we subtract 4580 from 4720, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
1400 divided by 916 is 1 with a remainder of 484.
Write down 1 as next digit of the result. 
Result so far: 1659.8045851
The remainder is 484 after subtracting 916 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 15:
916 can be fit into 4840 5 times, resulting in a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 1659.80458515
If we take 4580 away from 4840, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 1659.80458515, with a leftover of 2.6e-07.
