We're dividing 12831715 by 777 
Our goal is to divide 12831715 by 777.

Advancing to step 1:
The number 777 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 777

On to step 2:
When dividing 12 by 777, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 777

Advancing to step 3:
If we divide 128 by 777, we get 0 and a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Take the next digit (3) from the dividend and append it to 128, then repeat: 1283 / 777

Let's proceed to step 4:
The number 777 fits into 1283 1 times, leaving a remainder of 506.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 777 from 1283 to get 506.
Include the next digit (1) from the dividend after 506, then repeat: 5061 / 777

Advancing to step 5:
The number 777 fits into 5061 6 times, leaving a remainder of 399.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 4662 from 5061, we get 399.
Append the next digit (7) from the dividend to 399 and continue with: 3997 / 777

Going ahead to step 6:
777 can be fit into 3997 5 times, resulting in a remainder of 112.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 3885 from 3997 to get 112.
Take the next digit (1) from the dividend and append it to 112, then repeat: 1121 / 777

Step 7:
1121 divided by 777 is 1 with a remainder of 344.
Use 1 as the next digit of our solution. 
Result so far: 1651.0
Subtract 777 from 1121 to get 344.
Fetch the next digit (5) from the dividend, attach it to 344 and continue: 3445 / 777

Going ahead to step 8:
The number 777 fits into 3445 4 times, leaving a remainder of 337.
The number 4 becomes the next digit in our result. 
Result so far: 16514.0
If we subtract 3108 from 3445, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 9:
777 can be fit into 3370 4 times, resulting in a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 16514.4
Subtract 3108 from 3370 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 10:
2620 divided by 777 is 3 with a remainder of 289.
Write down 3 as next digit of the result. 
Result so far: 16514.43
The remainder is 289 after subtracting 2331 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 11:
The number 777 fits into 2890 3 times, leaving a remainder of 559.
Put 3 as the next digit of the answer. 
Result so far: 16514.433
If we take 2331 away from 2890, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Our division results in 16514.433 with a remaining 0.0559.
