We divide 662409 by 84
The aim is to understand the frequency of 84 in 662409.

Let's proceed to step 1:
6 divided by 84 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 84

Going ahead to step 2:
If we divide 66 by 84, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 84

Advancing to step 3:
When dividing 662 by 84, we get 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 588 from 662 and we're left with 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 84

On to step 4:
744 divided by 84 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 672 away from 744, we end up with 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 84

Advancing to step 5:
When dividing 720 by 84, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 788.0
If we take 672 away from 720, we end up with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 84

Going ahead to step 6:
84 goes into 489 5 times with a remainder of 69.
The next digit of our result is 5. 
Result so far: 7885.0
Subtracting 420 from 489 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
84 goes into 690 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 7885.8
Subtract 672 from 690 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.

Going ahead to step 8:
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: 7885.82
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 7885.821
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
360 divided by 84 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 7885.8214
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 7885.82142
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.

Going ahead to step 12:
If we divide 720 by 84, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 7885.821428
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.

Step 13:
480 divided by 84 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 7885.8214285
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
84 goes into 600 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 7885.82142857
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.

The final outcome is 7885.82142857, with a leftover of 1.2e-08.
