We're dividing 853113 by 84 
The aim is to understand the frequency of 84 in 853113.

Step 1:
8 divided by 84 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 84

On to step 2:
When dividing 85 by 84, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 84 from 85 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 84

Advancing to step 3:
84 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 13, we end up with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 84

Advancing to step 4:
131 divided by 84 is 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 101.0
The remainder is 47 after subtracting 84 from 131.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 84

Let's proceed to step 5:
When dividing 471 by 84, we get 5 with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 1015.0
Subtract 420 from 471 to get 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 84

Step 6:
If we divide 513 by 84, we get 6 and a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 10156.0
Subtract 504 from 513 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
84 goes into 90 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 10156.1
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 84 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10156.1
If we subtract 0 from 60, 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.

Moving on to step 9:
84 goes into 600 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 10156.107
If we take 588 away from 600, we end up 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.

Moving on to step 10:
84 goes into 120 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 10156.1071
Subtract 84 from 120 to 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 11:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 10156.10714
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.

Going ahead to step 12:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 10156.107142
Subtract 168 from 240 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 13:
The number 84 fits into 720 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 10156.1071428
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.

Let's proceed to step 14:
The number 84 fits into 480 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 10156.10714285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 10156.10714285 with a remaining 6e-08.
