586561 ÷ 84 
The aim is to understand the frequency of 84 in 586561.

On to step 1:
If we divide 5 by 84, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 84

Let's proceed to step 2:
When dividing 58 by 84, we get 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 84

Advancing to step 3:
586 divided by 84 is 6 with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 504 away from 586, we end up with 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 84

Step 4:
When dividing 825 by 84, we get 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 756 from 825, we get 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 84

Let's proceed to step 5:
696 divided by 84 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 698.0
If we take 672 away from 696, we end up with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 84

On to step 6:
241 divided by 84 is 2 with a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 6982.0
Deduct 168 from 241 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 7:
The number 84 fits into 730 8 times, leaving a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 6982.8
Subtract 672 from 730 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
The number 84 fits into 580 6 times, leaving a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 6982.86
If we take 504 away from 580, we end up 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 9:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 6982.869
If we subtract 756 from 760, we get 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 10:
The number 84 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 6982.869
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
84 goes into 400 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 6982.86904
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 12:
The number 84 fits into 640 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 6982.869047
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.

Let's proceed to step 13:
If we divide 520 by 84, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 6982.8690476
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.

Step 14:
When dividing 160 by 84, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 6982.86904761
Subtracting 84 from 160 leaves us 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.

The final result is 6982.86904761 with a remainder of 7.6e-08.
