Let's divide 126855 by 84
The aim is to understand the frequency of 84 in 126855.

Step 1:
84 can be fit into 1 0 times, resulting in 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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 84

Advancing to step 2:
84 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 84

Going ahead to step 3:
When dividing 126 by 84, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 84 from 126, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 84

Let's proceed to step 4:
The number 84 fits into 428 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 420 from 428 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 84

Going ahead to step 5:
84 can be fit into 85 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Subtracting 84 from 85 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 84

Let's proceed to step 6:
When dividing 15 by 84, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 1510.0
Subtract 0 from 15 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 84 is 1 with a remainder of 66.
The next digit of our result is 1. 
Result so far: 1510.1
If we take 84 away from 150, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
84 goes into 660 7 times with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 1510.17
If we take 588 away from 660, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
When dividing 720 by 84, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1510.178
Subtracting 672 from 720 leaves us 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.

Moving on to step 10:
When dividing 480 by 84, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 1510.1785
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1510.17857
If we subtract 588 from 600, we get 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 12:
84 goes into 120 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1510.178571
If we subtract 84 from 120, we 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.

Going ahead to step 13:
When dividing 360 by 84, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 1510.1785714
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.

On to step 14:
If we divide 240 by 84, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 1510.17857142
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 1510.17857142, and the remainder is 7.2e-08.
