Let's divide 16334523 by 77
The aim is to understand the frequency of 77 in 16334523.

Moving on to step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 77

Let's proceed to step 2:
16 divided by 77 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 77

On to step 3:
If we divide 163 by 77, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 154 from 163 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 77

Step 4:
The number 77 fits into 93 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 77 from 93 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 77

On to step 5:
When dividing 164 by 77, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 154 from 164 leaves us with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 77

Moving on to step 6:
If we divide 105 by 77, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 2121.0
Deduct 77 from 105 and we're left with 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 77

Let's proceed to step 7:
When dividing 282 by 77, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 21213.0
Subtract 231 from 282 to get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 77

Moving on to step 8:
If we divide 513 by 77, we get 6 and a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 212136.0
If we take 462 away from 513, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
If we divide 510 by 77, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 212136.6
Subtracting 462 from 510 leaves us 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.

Step 10:
The number 77 fits into 480 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 212136.66
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 212136.66 and a remainder of 0.018.
