620174 divided by 84 
The aim is to understand the frequency of 84 in 620174.

On to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 84

Step 2:
When dividing 62 by 84, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 84

Moving on to step 3:
When dividing 620 by 84, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 588 from 620 and we're left with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 84

Going ahead to step 4:
If we divide 321 by 84, we get 3 and a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 252 from 321 and we're left with 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 84

Advancing to step 5:
84 goes into 697 8 times with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 738.0
Deduct 672 from 697 and we're left with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 84

Advancing to step 6:
When dividing 254 by 84, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 7383.0
Subtract 252 from 254 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
84 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 7383.0
Subtracting 0 from 20 leaves us 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.

Moving on to step 8:
200 divided by 84 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 7383.02
Deduct 168 from 200 and we're left 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.

Let's proceed to step 9:
When dividing 320 by 84, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 7383.023
The remainder is 68 after subtracting 252 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
If we divide 680 by 84, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 7383.0238
If we take 672 away from 680, we end up 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.

Advancing to step 11:
84 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 7383.0238
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
800 divided by 84 is 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 7383.023809
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.

On to step 13:
84 can be fit into 440 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 7383.0238095
If we take 420 away from 440, we end up 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.

Going ahead to step 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 7383.02380952
Deduct 168 from 200 and we're left 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.

In conclusion, the division gives 7383.02380952 with a balance of 3.2e-08.
