We divide 989550 by 28
The aim is to understand the frequency of 28 in 989550.

Moving on to step 1:
9 divided by 28 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 28

Advancing to step 2:
28 can be fit into 98 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 84 from 98 to get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 28

Going ahead to step 3:
28 can be fit into 149 5 times, resulting in a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 140 away from 149, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 28

On to step 4:
The number 28 fits into 95 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 353.0
The remainder is 11 after subtracting 84 from 95.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 28

Advancing to step 5:
115 divided by 28 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 3534.0
If we subtract 112 from 115, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 28

Advancing to step 6:
28 can be fit into 30 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 35341.0
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 28 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 35341.0
If we subtract 0 from 20, we 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.

On to step 8:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 35341.07
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 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 35341.071
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.

Let's proceed to step 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 35341.0714
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 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 35341.07142
Deduct 56 from 80 and we're left 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 12:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 35341.071428
Deduct 224 from 240 and we're left 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.

Going ahead to step 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 35341.0714285
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.

Moving on to step 14:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 35341.07142857
If we take 196 away from 200, we end up 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.

The quotient of the division is 35341.07142857, and the remainder is 4e-09.
