We're dividing 501501 by 84 
The aim is to understand the frequency of 84 in 501501.

Advancing to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 84

Let's proceed to step 2:
When dividing 50 by 84, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 84

On to step 3:
The number 84 fits into 501 5 times, leaving a remainder of 81.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 81 after subtracting 420 from 501.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 84

On to step 4:
84 goes into 815 9 times with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we take 756 away from 815, we end up with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 84

On to step 5:
When dividing 590 by 84, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 597.0
Subtract 588 from 590 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 84

Let's proceed to step 6:
When dividing 21 by 84, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 5970.0
The remainder is 21 after subtracting 0 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
The number 84 fits into 210 2 times, leaving a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 5970.2
Deduct 168 from 210 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
84 goes into 420 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5970.25
The remainder is 0 after subtracting 420 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
84 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5970.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 84 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5970.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 5970.25 with a remainder of 0.0.
