Let's divide 684498 by 84
The aim is to understand the frequency of 84 in 684498.

Let's proceed to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 84

Advancing to step 2:
84 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 84

Let's proceed to step 3:
84 can be fit into 684 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 672 from 684 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 84

Going ahead to step 4:
124 divided by 84 is 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 84 away from 124, we end up with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 84

Advancing to step 5:
84 goes into 409 4 times with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 814.0
Deduct 336 from 409 and we're left with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 84

Going ahead to step 6:
738 divided by 84 is 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 8148.0
If we take 672 away from 738, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
84 can be fit into 660 7 times, resulting in a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 8148.7
Subtract 588 from 660 to 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.

Step 8:
When dividing 720 by 84, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 8148.78
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.

Going ahead to step 9:
If we divide 480 by 84, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 8148.785
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 84, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8148.7857
Subtract 588 from 600 to 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.

On to step 11:
If we divide 120 by 84, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 8148.78571
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.

Step 12:
When dividing 360 by 84, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8148.785714
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.

On to step 13:
When dividing 240 by 84, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 8148.7857142
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
84 goes into 720 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8148.78571428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 8148.78571428, with a leftover of 4.8e-08.
