245402 divided by 84 
The aim is to understand the frequency of 84 in 245402.

Step 1:
2 divided by 84 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 84

On to step 2:
84 can be fit into 24 0 times, resulting in a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 84

Step 3:
84 goes into 245 2 times with a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 168 from 245 to get 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 84

Advancing to step 4:
The number 84 fits into 774 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 756 from 774 leaves us with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 84

Advancing to step 5:
84 can be fit into 180 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 292.0
Deduct 168 from 180 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 84

Step 6:
122 divided by 84 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 2921.0
Subtract 84 from 122 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
380 divided by 84 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 2921.4
Subtracting 336 from 380 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 2921.45
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.

Moving on to step 9:
When dividing 200 by 84, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2921.452
Subtract 168 from 200 to 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.

On to step 10:
If we divide 320 by 84, we get 3 and a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 2921.4523
If we take 252 away from 320, we end up 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 11:
If we divide 680 by 84, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2921.45238
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 12:
80 divided by 84 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 2921.45238
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.

Going ahead to step 13:
When dividing 800 by 84, we get 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 2921.4523809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
When dividing 440 by 84, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 2921.45238095
Deduct 420 from 440 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.

Our division results in 2921.45238095 with a remaining 2e-08.
