Let's divide 50698644 by 77
The aim is to understand the frequency of 77 in 50698644.

Going ahead to step 1:
5 divided by 77 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 77

Step 2:
50 divided by 77 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 77

Moving on to step 3:
The number 77 fits into 506 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 462 from 506 to get 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 77

Advancing to step 4:
77 goes into 449 5 times with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 385 from 449 leaves us with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 77

Moving on to step 5:
If we divide 648 by 77, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 658.0
Deduct 616 from 648 and we're left with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 77

Advancing to step 6:
The number 77 fits into 326 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 6584.0
If we take 308 away from 326, we end up with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 77

Step 7:
184 divided by 77 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 65842.0
If we take 154 away from 184, we end up with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 77

Step 8:
When dividing 304 by 77, we get 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 658423.0
The remainder is 73 after subtracting 231 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 658423.9
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 658423.94
Deduct 308 from 370 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
77 goes into 620 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 658423.948
If we take 616 away from 620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
77 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 658423.948
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
77 can be fit into 400 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 658423.94805
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 658423.948051
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 15:
If we divide 730 by 77, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 658423.9480519
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 16:
370 divided by 77 is 4 with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 658423.94805194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 658423.94805194 with a balance of 6.2e-08.
