Let's divide 54291486 by 84
The aim is to understand the frequency of 84 in 54291486.

Advancing to step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 84

Step 2:
When dividing 54 by 84, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 84

Let's proceed to step 3:
The number 84 fits into 542 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 504 from 542 to get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 84

Advancing to step 4:
When dividing 389 by 84, we get 4 with a remainder of 53.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtracting 336 from 389 leaves us with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 84

On to step 5:
84 can be fit into 531 6 times, resulting in a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.0
Subtract 504 from 531 to get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 84

Step 6:
If we divide 274 by 84, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 6463.0
Deduct 252 from 274 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 84

Let's proceed to step 7:
The number 84 fits into 228 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 64632.0
If we subtract 168 from 228, we get 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 84

Going ahead to step 8:
84 can be fit into 606 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 646327.0
Subtract 588 from 606 to 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.

Step 9:
When dividing 180 by 84, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 646327.2
Deduct 168 from 180 and we're left 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.

Advancing to step 10:
120 divided by 84 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 646327.21
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 646327.214
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.

Step 12:
If we divide 240 by 84, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 646327.2142
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.

Moving on to step 13:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 646327.21428
If we subtract 672 from 720, 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.

Let's proceed to step 14:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 646327.214285
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.

Moving on to step 15:
If we divide 600 by 84, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 646327.2142857
Deduct 588 from 600 and we're left 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.

Going ahead to step 16:
84 goes into 120 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 646327.21428571
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.

After the division, we end up with 646327.21428571 and a remainder of 3.6e-08.
