We're dividing 25085706 by 84 
The aim is to understand the frequency of 84 in 25085706.

Let's proceed to step 1:
The number 84 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 84

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
Deduct 0 from 25 and we're left with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 84

Moving on to step 3:
If we divide 250 by 84, we get 2 and a remainder of 82.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 82 after subtracting 168 from 250.
Bring next digit (8) of the dividend behind the 82 and repeat the process: 828 / 84

Step 4:
If we divide 828 by 84, we get 9 and a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 756 from 828, we get 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 84

Step 5:
When dividing 725 by 84, we get 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 298.0
Deduct 672 from 725 and we're left with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 84

Step 6:
84 can be fit into 537 6 times, resulting in a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 2986.0
Subtract 504 from 537 to get 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 84

Step 7:
The number 84 fits into 330 3 times, leaving a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 29863.0
Deduct 252 from 330 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 84

Let's proceed to step 8:
If we divide 786 by 84, we get 9 and a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 298639.0
Deduct 756 from 786 and we're left 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.

Step 9:
84 goes into 300 3 times with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 298639.3
Deduct 252 from 300 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.

Step 10:
When dividing 480 by 84, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 298639.35
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
84 goes into 600 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 298639.357
Subtract 588 from 600 to get 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 12:
When dividing 120 by 84, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 298639.3571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
360 divided by 84 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 298639.35714
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 298639.357142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 15:
720 divided by 84 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 298639.3571428
Subtracting 672 from 720 leaves us 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 16:
84 goes into 480 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 298639.35714285
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 298639.35714285 with a remaining 6e-08.
