28115522 ÷ 997 
The aim is to understand the frequency of 997 in 28115522.

Going ahead to step 1:
2 divided by 997 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 997

On to step 2:
If we divide 28 by 997, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 997

On to step 3:
997 goes into 281 0 times with a remainder of 281.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 281 after subtracting 0 from 281.
Fetch the next digit (1) from the dividend, attach it to 281 and continue: 2811 / 997

Let's proceed to step 4:
If we divide 2811 by 997, we get 2 and a remainder of 817.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1994 from 2811 and we're left with 817.
Take the next digit (5) from the dividend and append it to 817, then repeat: 8175 / 997

Going ahead to step 5:
997 can be fit into 8175 8 times, resulting in a remainder of 199.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 7976 from 8175, we get 199.
Take the next digit (5) from the dividend and append it to 199, then repeat: 1995 / 997

Moving on to step 6:
997 can be fit into 1995 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 282.0
If we subtract 1994 from 1995, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 997

Moving on to step 7:
The number 997 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 2820.0
Subtract 0 from 12 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 997

Let's proceed to step 8:
If we divide 122 by 997, we get 0 and a remainder of 122.
Record the quotient 0 as the next digit in the result. 
Result so far: 28200.0
The remainder is 122 after subtracting 0 from 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 9:
997 can be fit into 1220 1 times, resulting in a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 28200.1
Deduct 997 from 1220 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 10:
997 goes into 2230 2 times with a remainder of 236.
The next digit of our result is 2. 
Result so far: 28200.12
The remainder is 236 after subtracting 1994 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
The number 997 fits into 2360 2 times, leaving a remainder of 366.
Write down 2 as next digit of the result. 
Result so far: 28200.122
The remainder is 366 after subtracting 1994 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Our division results in 28200.122 with a remaining 0.0366.
