29783543 ÷ 77 
The aim is to understand the frequency of 77 in 29783543.

Moving on to step 1:
If we divide 2 by 77, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 77

On to step 2:
77 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 77

Going ahead to step 3:
If we divide 297 by 77, we get 3 and a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 231 from 297, we get 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 77

Step 4:
If we divide 668 by 77, we get 8 and a remainder of 52.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 616 from 668 to get 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 77

Let's proceed to step 5:
When dividing 523 by 77, we get 6 with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
Subtracting 462 from 523 leaves us with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 77

Going ahead to step 6:
77 goes into 615 7 times with a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 3867.0
Deduct 539 from 615 and we're left with 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 77

Advancing to step 7:
77 goes into 764 9 times with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 38679.0
If we take 693 away from 764, we end up with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 77

On to step 8:
713 divided by 77 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 386799.0
The remainder is 20 after subtracting 693 from 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 77, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 386799.2
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.

Step 10:
77 can be fit into 460 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 386799.25
If we take 385 away from 460, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
The number 77 fits into 750 9 times, leaving a remainder of 57.
The next digit of our result is 9. 
Result so far: 386799.259
If we take 693 away from 750, 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.

Going ahead to step 12:
77 goes into 570 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 386799.2597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
77 goes into 310 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 386799.25974
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.

Let's proceed to step 14:
77 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 386799.25974
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
77 goes into 200 2 times with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 386799.2597402
If we subtract 154 from 200, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 16:
When dividing 460 by 77, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 386799.25974025
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 386799.25974025 with a remaining 7.5e-08.
