We're dividing 428738 by 84 
The aim is to understand the frequency of 84 in 428738.

Let's proceed to step 1:
The number 84 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 84

Let's proceed to step 2:
84 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 84

Let's proceed to step 3:
84 can be fit into 428 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 420 from 428 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 84

On to step 4:
87 divided by 84 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 84 from 87, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 84

Going ahead to step 5:
When dividing 33 by 84, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Subtract 0 from 33 to get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 84

Let's proceed to step 6:
If we divide 338 by 84, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 5104.0
Deduct 336 from 338 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 84, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5104.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 84, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 5104.02
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 5104.023
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 84 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5104.0238
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
80 divided by 84 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 5104.0238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
When dividing 800 by 84, we get 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 5104.023809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 5104.0238095
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
84 goes into 200 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 5104.02380952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 5104.02380952 and a remainder of 3.2e-08.
