Let's divide 640056 by 84
The aim is to understand the frequency of 84 in 640056.

Advancing to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 84

Moving on to step 2:
84 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 84

On to step 3:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 588 from 640 and we're left with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 84

Let's proceed to step 4:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 16 after subtracting 504 from 520.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 84

Moving on to step 5:
84 can be fit into 165 1 times, resulting in a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 761.0
Subtract 84 from 165 to get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 84

Let's proceed to step 6:
816 divided by 84 is 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 7619.0
Subtracting 756 from 816 leaves us 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.

Moving on to step 7:
When dividing 600 by 84, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7619.7
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 84, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 7619.71
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 9:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 7619.714
If we subtract 336 from 360, we get 24.
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 10:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 7619.7142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
If we divide 720 by 84, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 7619.71428
If we take 672 away from 720, we end up 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.

Going ahead to step 12:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 7619.714285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
84 goes into 600 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 7619.7142857
If we take 588 away from 600, we end up with 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 14:
If we divide 120 by 84, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 7619.71428571
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 7619.71428571 with a remainder of 3.6e-08.
