25970590 divided by 803 
The aim is to understand the frequency of 803 in 25970590.

Let's proceed to step 1:
When dividing 2 by 803, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 803

On to step 2:
803 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 803

Advancing to step 3:
The number 803 fits into 259 0 times, leaving a remainder of 259.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 259 leaves us with 259.
Grab the next digit (7) from the dividend, add it to 259, then carry on: 2597 / 803

Step 4:
When dividing 2597 by 803, we get 3 with a remainder of 188.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2409 from 2597, we get 188.
Grab the next digit (0) from the dividend, add it to 188, then carry on: 1880 / 803

Moving on to step 5:
1880 divided by 803 is 2 with a remainder of 274.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 1606 from 1880 leaves us with 274.
Grab the next digit (5) from the dividend, add it to 274, then carry on: 2745 / 803

Going ahead to step 6:
If we divide 2745 by 803, we get 3 and a remainder of 336.
Write down 3 as next digit of the result. 
Result so far: 323.0
If we subtract 2409 from 2745, we get 336.
Append the next digit (9) from the dividend to 336 and continue with: 3369 / 803

Let's proceed to step 7:
The number 803 fits into 3369 4 times, leaving a remainder of 157.
Write down 4 as next digit of the result. 
Result so far: 3234.0
Subtract 3212 from 3369 to get 157.
Include the next digit (0) from the dividend after 157, then repeat: 1570 / 803

On to step 8:
803 goes into 1570 1 times with a remainder of 767.
Put 1 as the next digit of the answer. 
Result so far: 32341.0
Subtracting 803 from 1570 leaves us with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Advancing to step 9:
When dividing 7670 by 803, we get 9 with a remainder of 443.
The next digit of our result is 9. 
Result so far: 32341.9
Subtract 7227 from 7670 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 10:
When dividing 4430 by 803, we get 5 with a remainder of 415.
The next digit of our result is 5. 
Result so far: 32341.95
Subtracting 4015 from 4430 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 11:
If we divide 4150 by 803, we get 5 and a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 32341.955
The remainder is 135 after subtracting 4015 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 32341.955 with a remainder of 0.0135.
