46428145 divided by 28 
The aim is to understand the frequency of 28 in 46428145.

Going ahead to step 1:
The number 28 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 28

Let's proceed to step 2:
28 can be fit into 46 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 28 away from 46, we end up with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 28

Moving on to step 3:
The number 28 fits into 184 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 168 from 184 to get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 28

Advancing to step 4:
28 can be fit into 162 5 times, resulting in a remainder of 22.
The next digit of our result is 5. 
Result so far: 165.0
If we subtract 140 from 162, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 28

Let's proceed to step 5:
28 can be fit into 228 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1658.0
Deduct 224 from 228 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 28

Moving on to step 6:
When dividing 41 by 28, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 16581.0
Subtracting 28 from 41 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 28

Let's proceed to step 7:
28 can be fit into 134 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 165814.0
Deduct 112 from 134 and we're left with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 28

Moving on to step 8:
28 goes into 225 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1658148.0
If we subtract 224 from 225, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
If we divide 10 by 28, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1658148.0
Subtracting 0 from 10 leaves us 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.

Going ahead to step 10:
28 can be fit into 100 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 1658148.03
If we take 84 away from 100, we end up 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 11:
When dividing 160 by 28, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 1658148.035
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1658148.0357
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.

Step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1658148.03571
The remainder is 12 after subtracting 28 from 40.
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 14:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1658148.035714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 15:
When dividing 80 by 28, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1658148.0357142
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 16:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1658148.03571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1658148.03571428, with a leftover of 1.6e-08.
