136951 divided by 84 
The aim is to understand the frequency of 84 in 136951.

On to step 1:
1 divided by 84 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 84

Moving on to step 2:
13 divided by 84 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 84

Going ahead to step 3:
136 divided by 84 is 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 52 after subtracting 84 from 136.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 84

On to step 4:
The number 84 fits into 529 6 times, leaving a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 504 away from 529, we end up with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 84

Going ahead to step 5:
84 can be fit into 255 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we subtract 252 from 255, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 84

Going ahead to step 6:
31 divided by 84 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 1630.0
The remainder is 31 after subtracting 0 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
84 goes into 310 3 times with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 1630.3
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
When dividing 580 by 84, we get 6 with a remainder of 76.
The next digit of our result is 6. 
Result so far: 1630.36
Subtract 504 from 580 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
If we divide 760 by 84, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1630.369
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.

Step 10:
When dividing 40 by 84, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1630.369
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing 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: 1630.36904
Subtracting 336 from 400 leaves us 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.

Step 12:
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: 1630.369047
If we subtract 588 from 640, we 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.

On to step 13:
520 divided by 84 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1630.3690476
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.

Let's proceed to step 14:
160 divided by 84 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1630.36904761
Subtract 84 from 160 to get 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 outcome is 1630.36904761, with a leftover of 7.6e-08.
