20129454 divided by 777 
We want to figure out the number of times 20129454 can be divided by 777.

Going ahead to step 1:
If we divide 2 by 777, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 777

Let's proceed to step 2:
777 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 777

Going ahead to step 3:
If we divide 201 by 777, we get 0 and a remainder of 201.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 201, we end up with 201.
Take the next digit (2) from the dividend and append it to 201, then repeat: 2012 / 777

Step 4:
2012 divided by 777 is 2 with a remainder of 458.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1554 from 2012 to get 458.
Include the next digit (9) from the dividend after 458, then repeat: 4589 / 777

Step 5:
777 can be fit into 4589 5 times, resulting in a remainder of 704.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 3885 from 4589 and we're left with 704.
Grab the next digit (4) from the dividend, add it to 704, then carry on: 7044 / 777

Moving on to step 6:
777 goes into 7044 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
The remainder is 51 after subtracting 6993 from 7044.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 777

Step 7:
515 divided by 777 is 0 with a remainder of 515.
Use 0 as the next digit of our solution. 
Result so far: 2590.0
If we take 0 away from 515, we end up with 515.
Bring next digit (4) of the dividend behind the 515 and repeat the process: 5154 / 777

Moving on to step 8:
777 can be fit into 5154 6 times, resulting in a remainder of 492.
Record the quotient 6 as the next digit in the result. 
Result so far: 25906.0
Deduct 4662 from 5154 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 9:
When dividing 4920 by 777, we get 6 with a remainder of 258.
The number 6 becomes the next digit in our result. 
Result so far: 25906.6
Subtract 4662 from 4920 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
777 can be fit into 2580 3 times, resulting in a remainder of 249.
Record the quotient 3 as the next digit in the result. 
Result so far: 25906.63
The remainder is 249 after subtracting 2331 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 11:
When dividing 2490 by 777, we get 3 with a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 25906.633
The remainder is 159 after subtracting 2331 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Our division results in 25906.633 with a remaining 0.0159.
