We're dividing 515950 by 77 
We want to divide 515950 by 77.

Going ahead to step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 77

Step 2:
77 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 77

Going ahead to step 3:
77 goes into 515 6 times with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 462 from 515 to get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 77

On to step 4:
77 goes into 539 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
The remainder is 0 after subtracting 539 from 539.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 77

Moving on to step 5:
If we divide 5 by 77, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 670.0
Subtract 0 from 5 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 77

Advancing to step 6:
When dividing 50 by 77, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6700.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
When dividing 500 by 77, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 6700.6
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
380 divided by 77 is 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 6700.64
If we subtract 308 from 380, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
When dividing 720 by 77, we get 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 6700.649
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
270 divided by 77 is 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 6700.6493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
390 divided by 77 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6700.64935
If we subtract 385 from 390, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 77 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6700.64935
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 77 fits into 500 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 6700.6493506
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
77 can be fit into 380 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 6700.64935064
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 6700.64935064 and a remainder of 7.2e-08.
