89851656 divided by 28 
The aim is to understand the frequency of 28 in 89851656.

Step 1:
8 divided by 28 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 28

Advancing to step 2:
If we divide 89 by 28, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 84 from 89 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 28

Let's proceed to step 3:
28 can be fit into 58 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 56 away from 58, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 28

Step 4:
28 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 320.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 28

On to step 5:
When dividing 251 by 28, we get 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 3208.0
If we subtract 224 from 251, we get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 28

Advancing to step 6:
28 can be fit into 276 9 times, resulting in a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 32089.0
Subtracting 252 from 276 leaves us with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 28

Going ahead to step 7:
If we divide 245 by 28, we get 8 and a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 320898.0
If we take 224 away from 245, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 28

Step 8:
216 divided by 28 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 3208987.0
Subtract 196 from 216 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 9:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 3208987.7
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.

Going ahead to step 10:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 3208987.71
Deduct 28 from 40 and we're left 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 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3208987.714
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 12:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3208987.7142
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.

On to step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 3208987.71428
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.

Moving on to step 14:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3208987.714285
The remainder is 20 after subtracting 140 from 160.
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 15:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 3208987.7142857
Deduct 196 from 200 and we're left 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.

Advancing to step 16:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 3208987.71428571
Subtract 28 from 40 to 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.

Our division results in 3208987.71428571 with a remaining 1.2e-08.
