Let's divide 89610188 by 251
The aim is to understand the frequency of 251 in 89610188.

Going ahead to step 1:
The number 251 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 251

On to step 2:
When dividing 89 by 251, we get 0 with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Include the next digit (6) from the dividend after 89, then repeat: 896 / 251

Moving on to step 3:
If we divide 896 by 251, we get 3 and a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 753 from 896, we get 143.
Grab the next digit (1) from the dividend, add it to 143, then carry on: 1431 / 251

Advancing to step 4:
251 goes into 1431 5 times with a remainder of 176.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 176 after subtracting 1255 from 1431.
Bring next digit (0) of the dividend behind the 176 and repeat the process: 1760 / 251

Let's proceed to step 5:
If we divide 1760 by 251, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 357.0
If we subtract 1757 from 1760, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 251

On to step 6:
If we divide 31 by 251, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 3570.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 251

Moving on to step 7:
251 can be fit into 318 1 times, resulting in a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 35701.0
Deduct 251 from 318 and we're left with 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 251

Moving on to step 8:
251 can be fit into 678 2 times, resulting in a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 357012.0
If we subtract 502 from 678, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 9:
When dividing 1760 by 251, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 357012.7
If we take 1757 away from 1760, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
251 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 357012.7
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
251 goes into 300 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 357012.701
If we subtract 251 from 300, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
When dividing 490 by 251, we get 1 with a remainder of 239.
The next digit of our result is 1. 
Result so far: 357012.7011
If we take 251 away from 490, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The final result is 357012.7011 with a remainder of 0.00239.
