We look at the division of 2557061 by 789 
The aim is to understand the frequency of 789 in 2557061.

Let's proceed to step 1:
When dividing 2 by 789, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 789

On to step 2:
25 divided by 789 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 789

Let's proceed to step 3:
When dividing 255 by 789, we get 0 with a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 255, we end up with 255.
Grab the next digit (7) from the dividend, add it to 255, then carry on: 2557 / 789

Step 4:
2557 divided by 789 is 3 with a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 190 after subtracting 2367 from 2557.
Bring next digit (0) of the dividend behind the 190 and repeat the process: 1900 / 789

Going ahead to step 5:
789 goes into 1900 2 times with a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we take 1578 away from 1900, we end up with 322.
Append the next digit (6) from the dividend to 322 and continue with: 3226 / 789

Advancing to step 6:
If we divide 3226 by 789, we get 4 and a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 324.0
If we subtract 3156 from 3226, we get 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 789

On to step 7:
701 divided by 789 is 0 with a remainder of 701.
The next digit of our result is 0. 
Result so far: 3240.0
Deduct 0 from 701 and we're left with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Advancing to step 8:
7010 divided by 789 is 8 with a remainder of 698.
Write down 8 as next digit of the result. 
Result so far: 3240.8
Deduct 6312 from 7010 and we're left with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Moving on to step 9:
789 can be fit into 6980 8 times, resulting in a remainder of 668.
Put 8 as the next digit of the answer. 
Result so far: 3240.88
The remainder is 668 after subtracting 6312 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

In conclusion, the division gives 3240.88 with a balance of 0.668.
