Let's divide 85684346 by 84
The aim is to understand the frequency of 84 in 85684346.

Going ahead to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 84

Moving on to step 2:
The number 84 fits into 85 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 84 from 85, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 84

Moving on to step 3:
The number 84 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 16, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 84

Step 4:
When dividing 168 by 84, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 0 after subtracting 168 from 168.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 84

Step 5:
When dividing 4 by 84, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 1020.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 84

Advancing to step 6:
When dividing 43 by 84, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 10200.0
If we subtract 0 from 43, we get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 84

Moving on to step 7:
The number 84 fits into 434 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 102005.0
If we take 420 away from 434, we end up with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 84

Advancing to step 8:
If we divide 146 by 84, we get 1 and a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1020051.0
The remainder is 62 after subtracting 84 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
When dividing 620 by 84, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 1020051.7
Subtracting 588 from 620 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
84 goes into 320 3 times with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 1020051.73
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1020051.738
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
84 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1020051.738
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
If we divide 800 by 84, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 1020051.73809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 1020051.738095
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
84 goes into 200 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 1020051.7380952
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 1020051.73809523
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 1020051.73809523, with a leftover of 6.8e-08.
