257630 divided by 89 
The aim is to understand the frequency of 89 in 257630.

Moving on to step 1:
2 divided by 89 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 89

Let's proceed to step 2:
If we divide 25 by 89, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 89

On to step 3:
89 can be fit into 257 2 times, resulting in a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 79 after subtracting 178 from 257.
Fetch the next digit (6) from the dividend, attach it to 79 and continue: 796 / 89

Moving on to step 4:
When dividing 796 by 89, we get 8 with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 712 away from 796, we end up with 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 89

Step 5:
If we divide 843 by 89, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 289.0
Subtracting 801 from 843 leaves us with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 89

Advancing to step 6:
If we divide 420 by 89, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 2894.0
The remainder is 64 after subtracting 356 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
89 can be fit into 640 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 2894.7
Subtract 623 from 640 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
89 goes into 170 1 times with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 2894.71
Subtract 89 from 170 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
89 goes into 810 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 2894.719
The remainder is 9 after subtracting 801 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
If we divide 90 by 89, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 2894.7191
If we take 89 away from 90, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
89 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2894.7191
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
89 goes into 100 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2894.719101
Subtracting 89 from 100 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
The number 89 fits into 110 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 2894.7191011
Subtracting 89 from 110 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 2894.7191011 with a remaining 2.1e-07.
