We look at the division of 11005025 by 897 
The aim is to understand the frequency of 897 in 11005025.

Moving on to step 1:
897 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 897

On to step 2:
897 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 897

On to step 3:
897 can be fit into 110 0 times, resulting in a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 110 after subtracting 0 from 110.
Fetch the next digit (0) from the dividend, attach it to 110 and continue: 1100 / 897

Let's proceed to step 4:
1100 divided by 897 is 1 with a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 897 from 1100, we get 203.
Grab the next digit (5) from the dividend, add it to 203, then carry on: 2035 / 897

Advancing to step 5:
897 can be fit into 2035 2 times, resulting in a remainder of 241.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1794 from 2035 to get 241.
Bring next digit (0) of the dividend behind the 241 and repeat the process: 2410 / 897

Moving on to step 6:
2410 divided by 897 is 2 with a remainder of 616.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 1794 from 2410 to get 616.
Bring next digit (2) of the dividend behind the 616 and repeat the process: 6162 / 897

Let's proceed to step 7:
6162 divided by 897 is 6 with a remainder of 780.
The number 6 becomes the next digit in our result. 
Result so far: 1226.0
Subtract 5382 from 6162 to get 780.
Bring next digit (5) of the dividend behind the 780 and repeat the process: 7805 / 897

Advancing to step 8:
If we divide 7805 by 897, we get 8 and a remainder of 629.
Write down 8 as next digit of the result. 
Result so far: 12268.0
Subtract 7176 from 7805 to get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Let's proceed to step 9:
897 can be fit into 6290 7 times, resulting in a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 12268.7
If we subtract 6279 from 6290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
If we divide 110 by 897, we get 0 and a remainder of 110.
The next digit of our result is 0. 
Result so far: 12268.7
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
897 can be fit into 1100 1 times, resulting in a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 12268.701
Subtract 897 from 1100 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 12:
897 can be fit into 2030 2 times, resulting in a remainder of 236.
The next digit of our result is 2. 
Result so far: 12268.7012
If we take 1794 away from 2030, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 13:
If we divide 2360 by 897, we get 2 and a remainder of 566.
Use 2 as the next digit of our solution. 
Result so far: 12268.70122
If we subtract 1794 from 2360, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

After the division, we end up with 12268.70122 and a remainder of 0.000566.
