Let's divide 257781 by 84
The aim is to understand the frequency of 84 in 257781.

Going ahead to step 1:
84 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
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 / 84

Moving on to step 2:
25 divided by 84 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 84

On to step 3:
84 can be fit into 257 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 5 after subtracting 252 from 257.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 84

Step 4:
When dividing 57 by 84, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 84

Advancing to step 5:
When dividing 578 by 84, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 306.0
Subtract 504 from 578 to get 74.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 84

Moving on to step 6:
741 divided by 84 is 8 with a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 3068.0
Subtract 672 from 741 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
84 can be fit into 690 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 3068.8
If we subtract 672 from 690, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
84 goes into 180 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 3068.82
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 3068.821
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
When dividing 360 by 84, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 3068.8214
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 84, we get 2 and a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 3068.82142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
If we divide 720 by 84, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 3068.821428
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
If we divide 480 by 84, we get 5 and a remainder of 60.
The next digit of our result is 5. 
Result so far: 3068.8214285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 3068.82142857
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 3068.82142857, with a leftover of 1.2e-08.
