Let's divide 395669 by 77
We want to divide 395669 by 77.

On to step 1:
77 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 77

On to step 2:
If we divide 39 by 77, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 77

On to step 3:
If we divide 395 by 77, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 10 after subtracting 385 from 395.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 77

Step 4:
77 can be fit into 106 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 77 from 106 to get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 77

On to step 5:
77 can be fit into 296 3 times, resulting in a remainder of 65.
The next digit of our result is 3. 
Result so far: 513.0
The remainder is 65 after subtracting 231 from 296.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 77

Going ahead to step 6:
77 can be fit into 659 8 times, resulting in a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 5138.0
Deduct 616 from 659 and we're left 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.

Step 7:
77 goes into 430 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 5138.5
The remainder is 45 after subtracting 385 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
77 goes into 450 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 5138.55
Subtracting 385 from 450 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 5138.55 with a remainder of 0.065.
