585418 divided by 84 
The aim is to understand the frequency of 84 in 585418.

Step 1:
If we divide 5 by 84, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 84

On to step 2:
58 divided by 84 is 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 84

Advancing to step 3:
84 goes into 585 6 times with a remainder of 81.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 504 away from 585, we end up with 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 84

Moving on to step 4:
When dividing 814 by 84, we get 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 58 after subtracting 756 from 814.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 84

Going ahead to step 5:
The number 84 fits into 581 6 times, leaving a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 696.0
Deduct 504 from 581 and we're left with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 84

Let's proceed to step 6:
84 goes into 778 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 6969.0
The remainder is 22 after subtracting 756 from 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
220 divided by 84 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 6969.2
If we take 168 away from 220, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6969.26
Deduct 504 from 520 and we're left 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.

On to step 9:
160 divided by 84 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 6969.261
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
The number 84 fits into 760 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 6969.2619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
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: 6969.2619
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.

Going ahead to step 12:
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: 6969.261904
If we take 336 away from 400, we end up 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.

Advancing to step 13:
84 can be fit into 640 7 times, resulting in a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 6969.2619047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
84 goes into 520 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 6969.26190476
If we take 504 away from 520, we end up 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.

The quotient of the division is 6969.26190476, and the remainder is 1.6e-08.
