29009 divided by 77 
The aim is to understand the frequency of 77 in 29009.

Step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 77

On to step 2:
29 divided by 77 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 77

Let's proceed to step 3:
77 can be fit into 290 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 231 from 290 and we're left with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 77

Step 4:
590 divided by 77 is 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 539 from 590 to get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 77

On to step 5:
If we divide 519 by 77, we get 6 and a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 376.0
If we take 462 away from 519, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 6:
When dividing 570 by 77, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 376.7
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
77 can be fit into 310 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 376.74
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
77 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 376.74
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 77 fits into 200 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 376.7402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 77, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 376.74025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
750 divided by 77 is 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 376.740259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 12:
When dividing 570 by 77, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 376.7402597
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
The number 77 fits into 310 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 376.74025974
Subtracting 308 from 310 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 376.74025974, with a leftover of 2e-09.
