We're dividing 913935 by 28 
The aim is to understand the frequency of 28 in 913935.

Advancing to step 1:
If we divide 9 by 28, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 28

Step 2:
When dividing 91 by 28, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 84 away from 91, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 28

Going ahead to step 3:
If we divide 73 by 28, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 56 away from 73, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 28

On to step 4:
28 can be fit into 179 6 times, resulting in a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
If we take 168 away from 179, we end up with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 28

Let's proceed to step 5:
28 can be fit into 113 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 3264.0
Subtract 112 from 113 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 28

Let's proceed to step 6:
If we divide 15 by 28, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 32640.0
Subtracting 0 from 15 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 28, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 32640.5
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 28, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 32640.53
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 32640.535
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 32640.5357
The remainder is 4 after subtracting 196 from 200.
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 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 32640.53571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 32640.535714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 32640.5357142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 32640.53571428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 32640.53571428 and a remainder of 1.6e-08.
