29050439 ÷ 77 
The aim is to understand the frequency of 77 in 29050439.

Step 1:
If we divide 2 by 77, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 77

Going ahead to step 2:
If we divide 29 by 77, we get 0 and a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 77

On to step 3:
77 goes into 290 3 times with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 231 from 290 to get 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 77

Moving on to step 4:
595 divided by 77 is 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 539 from 595 leaves us with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 77

Advancing to step 5:
If we divide 560 by 77, we get 7 and a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 377.0
Subtracting 539 from 560 leaves us with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 77

On to step 6:
214 divided by 77 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3772.0
Subtracting 154 from 214 leaves us with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 77

Going ahead to step 7:
603 divided by 77 is 7 with a remainder of 64.
The next digit of our result is 7. 
Result so far: 37727.0
Subtracting 539 from 603 leaves us with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 77

Step 8:
When dividing 649 by 77, we get 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 377278.0
Subtracting 616 from 649 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
The number 77 fits into 330 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 377278.4
If we take 308 away from 330, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
77 can be fit into 220 2 times, resulting in a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 377278.42
The remainder is 66 after subtracting 154 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
660 divided by 77 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 377278.428
If we subtract 616 from 660, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 77 fits into 440 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 377278.4285
Subtracting 385 from 440 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
If we divide 550 by 77, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 377278.42857
If we take 539 away from 550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
77 can be fit into 110 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 377278.428571
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 15:
330 divided by 77 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 377278.4285714
If we subtract 308 from 330, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
The number 77 fits into 220 2 times, leaving a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 377278.42857142
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 377278.42857142, with a leftover of 6.6e-08.
