We divide 85748923 by 28
The aim is to understand the frequency of 28 in 85748923.

On to step 1:
8 divided by 28 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 28

Moving on to step 2:
When dividing 85 by 28, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 84 from 85, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 28

Moving on to step 3:
When dividing 17 by 28, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 28

On to step 4:
The number 28 fits into 174 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
If we take 168 away from 174, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 28

Step 5:
28 can be fit into 68 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3062.0
Subtract 56 from 68 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 28

Moving on to step 6:
If we divide 129 by 28, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 30624.0
The remainder is 17 after subtracting 112 from 129.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 28

Step 7:
When dividing 172 by 28, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 306246.0
If we take 168 away from 172, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 28

On to step 8:
The number 28 fits into 43 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 3062461.0
Subtract 28 from 43 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 28 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3062461.5
Subtracting 140 from 150 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.

Step 10:
28 can be fit into 100 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3062461.53
If we subtract 84 from 100, 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.

Moving on to step 11:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3062461.535
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.

Advancing to step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3062461.5357
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 3062461.53571
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.

Advancing 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: 3062461.535714
The remainder is 8 after subtracting 112 from 120.
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 15:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3062461.5357142
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.

Moving on to step 16:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3062461.53571428
Subtract 224 from 240 to 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.

In conclusion, the division gives 3062461.53571428 with a balance of 1.6e-08.
