We're dividing 1396866 by 777 
Our goal is to divide 1396866 by 777.

Step 1:
777 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 777

Going ahead to step 2:
The number 777 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 777

Advancing to step 3:
The number 777 fits into 139 0 times, leaving a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 139 after subtracting 0 from 139.
Include the next digit (6) from the dividend after 139, then repeat: 1396 / 777

On to step 4:
If we divide 1396 by 777, we get 1 and a remainder of 619.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 777 from 1396, we get 619.
Grab the next digit (8) from the dividend, add it to 619, then carry on: 6198 / 777

Let's proceed to step 5:
777 goes into 6198 7 times with a remainder of 759.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 5439 from 6198, we get 759.
Take the next digit (6) from the dividend and append it to 759, then repeat: 7596 / 777

Advancing to step 6:
777 can be fit into 7596 9 times, resulting in a remainder of 603.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtracting 6993 from 7596 leaves us with 603.
Fetch the next digit (6) from the dividend, attach it to 603 and continue: 6036 / 777

On to step 7:
777 goes into 6036 7 times with a remainder of 597.
The number 7 becomes the next digit in our result. 
Result so far: 1797.0
The remainder is 597 after subtracting 5439 from 6036.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Advancing to step 8:
777 can be fit into 5970 7 times, resulting in a remainder of 531.
Put 7 as the next digit of the answer. 
Result so far: 1797.7
The remainder is 531 after subtracting 5439 from 5970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 9:
777 can be fit into 5310 6 times, resulting in a remainder of 648.
Write down 6 as next digit of the result. 
Result so far: 1797.76
If we subtract 4662 from 5310, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 10:
777 goes into 6480 8 times with a remainder of 264.
Record the quotient 8 as the next digit in the result. 
Result so far: 1797.768
If we take 6216 away from 6480, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 11:
777 can be fit into 2640 3 times, resulting in a remainder of 309.
Put 3 as the next digit of the answer. 
Result so far: 1797.7683
If we subtract 2331 from 2640, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 12:
If we divide 3090 by 777, we get 3 and a remainder of 759.
Write down 3 as next digit of the result. 
Result so far: 1797.76833
Subtract 2331 from 3090 to get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

After the division, we end up with 1797.76833 and a remainder of 0.000759.
