We divide 23493870 by 28
The aim is to understand the frequency of 28 in 23493870.

Let's proceed to step 1:
28 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 28

On to step 2:
When dividing 23 by 28, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 28

Step 3:
When dividing 234 by 28, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 224 from 234 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 28

Going ahead to step 4:
28 can be fit into 109 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 84 from 109 to get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 28

Step 5:
28 goes into 253 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
If we take 252 away from 253, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 28

Advancing to step 6:
If we divide 18 by 28, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 8390.0
If we subtract 0 from 18, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 28

On to step 7:
187 divided by 28 is 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 83906.0
Subtracting 168 from 187 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 28

On to step 8:
28 can be fit into 190 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 839066.0
Subtracting 168 from 190 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
When dividing 220 by 28, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 839066.7
Subtracting 196 from 220 leaves us 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.

Going ahead to step 10:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 839066.78
Subtracting 224 from 240 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.

On to step 11:
160 divided by 28 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 839066.785
If we take 140 away from 160, we end up 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 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 839066.7857
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 839066.78571
If we take 28 away from 40, we end up with 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 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 839066.785714
If we take 112 away from 120, we end up 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.

On to step 15:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 839066.7857142
Subtracting 56 from 80 leaves us 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:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 839066.78571428
Subtracting 224 from 240 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.

Our division results in 839066.78571428 with a remaining 1.6e-08.
