810261 divided by 84 
The aim is to understand the frequency of 84 in 810261.

Step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 84

Going ahead to step 2:
84 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 84

Let's proceed to step 3:
84 goes into 810 9 times with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 756 from 810, we get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 84

Moving on to step 4:
542 divided by 84 is 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we subtract 504 from 542, we get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 84

Step 5:
When dividing 386 by 84, we get 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 964.0
Subtracting 336 from 386 leaves us with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 84

Let's proceed to step 6:
The number 84 fits into 501 5 times, leaving a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 9645.0
If we take 420 away from 501, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
If we divide 810 by 84, we get 9 and a remainder of 54.
The next digit of our result is 9. 
Result so far: 9645.9
Subtracting 756 from 810 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
84 goes into 540 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 9645.96
Subtract 504 from 540 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.

Let's proceed to step 9:
84 goes into 360 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 9645.964
Subtracting 336 from 360 leaves us 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.

Let's proceed to step 10:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 9645.9642
If we subtract 168 from 240, we 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.

Moving on to step 11:
720 divided by 84 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 9645.96428
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.

Going ahead to step 12:
84 goes into 480 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9645.964285
The remainder is 60 after subtracting 420 from 480.
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 13:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 9645.9642857
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.

Going ahead to step 14:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 9645.96428571
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.

The final result is 9645.96428571 with a remainder of 3.6e-08.
