620786 ÷ 77 
Our goal is to divide 620786 by 77.

Step 1:
The number 77 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 77

Let's proceed to step 2:
77 can be fit into 62 0 times, resulting in a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 77

Going ahead to step 3:
When dividing 620 by 77, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 616 from 620 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 77

On to step 4:
When dividing 47 by 77, we get 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we subtract 0 from 47, we get 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 77

Advancing to step 5:
77 can be fit into 478 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 806.0
Subtract 462 from 478 to get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 77

Advancing to step 6:
If we divide 166 by 77, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 8062.0
Deduct 154 from 166 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 77, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 8062.1
Subtracting 77 from 120 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
The number 77 fits into 430 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 8062.15
Subtract 385 from 430 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
When dividing 450 by 77, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 8062.155
If we subtract 385 from 450, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 8062.155 and a remainder of 0.0065.
