We look at the division of 32901024 by 251 
The aim is to understand the frequency of 251 in 32901024.

Advancing to step 1:
3 divided by 251 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 251

Moving on to step 2:
The number 251 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 251

Moving on to step 3:
251 goes into 329 1 times with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 251 from 329 and we're left with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 251

Advancing to step 4:
251 goes into 780 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 27 after subtracting 753 from 780.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 251

Let's proceed to step 5:
When dividing 271 by 251, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Subtract 251 from 271 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 251

Let's proceed to step 6:
200 divided by 251 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 1310.0
Subtracting 0 from 200 leaves us with 200.
Fetch the next digit (2) from the dividend, attach it to 200 and continue: 2002 / 251

Let's proceed to step 7:
2002 divided by 251 is 7 with a remainder of 245.
Use 7 as the next digit of our solution. 
Result so far: 13107.0
The remainder is 245 after subtracting 1757 from 2002.
Take the next digit (4) from the dividend and append it to 245, then repeat: 2454 / 251

Going ahead to step 8:
251 goes into 2454 9 times with a remainder of 195.
Record the quotient 9 as the next digit in the result. 
Result so far: 131079.0
If we subtract 2259 from 2454, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 9:
If we divide 1950 by 251, we get 7 and a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 131079.7
If we subtract 1757 from 1950, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 10:
If we divide 1930 by 251, we get 7 and a remainder of 173.
Write down 7 as next digit of the result. 
Result so far: 131079.77
The remainder is 173 after subtracting 1757 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Our division results in 131079.77 with a remaining 0.173.
