We divide 55137 by 77
The aim is to understand the frequency of 77 in 55137.

On to step 1:
5 divided by 77 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 77

Step 2:
When dividing 55 by 77, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 77

Step 3:
The number 77 fits into 551 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 539 from 551 and we're left with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 77

Going ahead to step 4:
77 can be fit into 123 1 times, resulting in a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Deduct 77 from 123 and we're left with 46.
Append the next digit (7) from the dividend to 46 and continue with: 467 / 77

Let's proceed to step 5:
467 divided by 77 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 716.0
Subtracting 462 from 467 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
77 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 716.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
The number 77 fits into 500 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 716.06
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
The number 77 fits into 380 4 times, leaving a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 716.064
Subtracting 308 from 380 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
77 can be fit into 720 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 716.0649
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
270 divided by 77 is 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 716.06493
Subtracting 231 from 270 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
77 can be fit into 390 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 716.064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 77 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 716.064935
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
77 goes into 500 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 716.06493506
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 716.06493506, with a leftover of 3.8e-08.
