Let's divide 66373664 by 84
The aim is to understand the frequency of 84 in 66373664.

Going ahead to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 84

Let's proceed to step 2:
84 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 84

Going ahead to step 3:
84 can be fit into 663 7 times, resulting in a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 588 away from 663, we end up with 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 84

Advancing to step 4:
When dividing 757 by 84, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 756 from 757 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 84

Let's proceed to step 5:
13 divided by 84 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 790.0
If we take 0 away from 13, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 84

Step 6:
The number 84 fits into 136 1 times, leaving a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 7901.0
If we subtract 84 from 136, we get 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 84

Moving on to step 7:
84 can be fit into 526 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 79016.0
Subtract 504 from 526 to get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 84

Moving on to step 8:
84 goes into 224 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 790162.0
Subtract 168 from 224 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
84 goes into 560 6 times with a remainder of 56.
The next digit of our result is 6. 
Result so far: 790162.6
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
84 goes into 560 6 times with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 790162.66
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 790162.66 with a remainder of 0.056.
