We're dividing 249175 by 84 
The aim is to understand the frequency of 84 in 249175.

On to step 1:
84 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 84

Advancing to step 2:
24 divided by 84 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 84

Going ahead to step 3:
If we divide 249 by 84, we get 2 and a remainder of 81.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 168 from 249 to get 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 84

Moving on to step 4:
811 divided by 84 is 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 756 away from 811, we end up with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 84

Step 5:
84 can be fit into 557 6 times, resulting in a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 296.0
If we subtract 504 from 557, we get 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 84

On to step 6:
535 divided by 84 is 6 with a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 2966.0
Subtract 504 from 535 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
310 divided by 84 is 3 with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 2966.3
Deduct 252 from 310 and we're left 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.

Moving on to step 8:
If we divide 580 by 84, we get 6 and a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 2966.36
If we take 504 away from 580, we end up 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.

On to step 9:
84 goes into 760 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 2966.369
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.

Advancing to step 10:
When dividing 40 by 84, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2966.369
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 84, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 2966.36904
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.

On to step 12:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 2966.369047
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.

Step 13:
The number 84 fits into 520 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 2966.3690476
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The next digit of our result is 1. 
Result so far: 2966.36904761
Deduct 84 from 160 and we're left 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.

The final outcome is 2966.36904761, with a leftover of 7.6e-08.
