We look at the division of 536503 by 84 
The aim is to understand the frequency of 84 in 536503.

Advancing to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 84

Going ahead to step 2:
The number 84 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 84

Advancing to step 3:
The number 84 fits into 536 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 504 from 536 and we're left with 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 84

Advancing to step 4:
If we divide 325 by 84, we get 3 and a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 252 away from 325, we end up with 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 84

Let's proceed to step 5:
84 goes into 730 8 times with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 638.0
Subtract 672 from 730 to get 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 84

Step 6:
583 divided by 84 is 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 6386.0
Deduct 504 from 583 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
The number 84 fits into 790 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 6386.9
The remainder is 34 after subtracting 756 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
84 goes into 340 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 6386.94
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
84 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6386.94
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.

Step 10:
84 can be fit into 400 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 6386.9404
If we take 336 away from 400, we end up 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 11:
84 goes into 640 7 times with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 6386.94047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
When dividing 520 by 84, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6386.940476
If we subtract 504 from 520, we get 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 13:
84 goes into 160 1 times with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 6386.9404761
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
When dividing 760 by 84, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 6386.94047619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 6386.94047619 with a remaining 4e-09.
