We look at the division of 816190 by 84 
The aim is to understand the frequency of 84 in 816190.

Let's proceed to step 1:
84 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 84

Going ahead to step 2:
If we divide 81 by 84, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 84

Going ahead to step 3:
The number 84 fits into 816 9 times, leaving a remainder of 60.
The next digit of our result is 9. 
Result so far: 9.0
If we take 756 away from 816, we end up with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 84

Going ahead to step 4:
When dividing 601 by 84, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 588 away from 601, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 84

Advancing to step 5:
84 can be fit into 139 1 times, resulting in a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 971.0
Subtract 84 from 139 to get 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 84

Let's proceed to step 6:
550 divided by 84 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 9716.0
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
460 divided by 84 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 9716.5
Subtract 420 from 460 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 9716.54
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 84 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 9716.547
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
If we divide 520 by 84, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 9716.5476
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 84, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 9716.54761
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
When dividing 760 by 84, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9716.547619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 84, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9716.547619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 9716.54761904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 9716.54761904, and the remainder is 6.4e-08.
