77128746 ÷ 84 
The aim is to understand the frequency of 84 in 77128746.

On to step 1:
84 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 84

Moving on to step 2:
77 divided by 84 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 84

Step 3:
If we divide 771 by 84, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 756 from 771 leaves us with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 84

Step 4:
If we divide 152 by 84, we get 1 and a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 84 from 152 and we're left with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 84

Let's proceed to step 5:
The number 84 fits into 688 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 918.0
The remainder is 16 after subtracting 672 from 688.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 84

Moving on to step 6:
167 divided by 84 is 1 with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 9181.0
Subtracting 84 from 167 leaves us with 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 84

Let's proceed to step 7:
84 goes into 834 9 times with a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 91819.0
The remainder is 78 after subtracting 756 from 834.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 84

Let's proceed to step 8:
The number 84 fits into 786 9 times, leaving a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 918199.0
If we take 756 away from 786, we end up 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.

Let's proceed to step 9:
84 can be fit into 300 3 times, resulting in a remainder of 48.
The next digit of our result is 3. 
Result so far: 918199.3
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
480 divided by 84 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 918199.35
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.

Advancing to step 11:
When dividing 600 by 84, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 918199.357
Subtracting 588 from 600 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 12:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 918199.3571
If we subtract 84 from 120, we 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.

Let's proceed 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: 918199.35714
Deduct 336 from 360 and we're left 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.

Advancing to step 14:
When dividing 240 by 84, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 918199.357142
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.

On to step 15:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 918199.3571428
Subtract 672 from 720 to get 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 16:
480 divided by 84 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 918199.35714285
If we subtract 420 from 480, we 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.

In conclusion, the division gives 918199.35714285 with a balance of 6e-08.
