We're dividing 196439 by 77 
Our goal is to divide 196439 by 77.

Step 1:
1 divided by 77 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 77

Advancing to step 2:
77 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 77

Going ahead to step 3:
If we divide 196 by 77, we get 2 and a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 154 from 196 leaves us with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 77

Let's proceed to step 4:
When dividing 424 by 77, we get 5 with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 385 from 424 leaves us with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 77

Moving on to step 5:
If we divide 393 by 77, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 255.0
Subtracting 385 from 393 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 77

Step 6:
If we divide 89 by 77, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2551.0
Deduct 77 from 89 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:
When dividing 120 by 77, we get 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 2551.1
Subtract 77 from 120 to get 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:
77 can be fit into 430 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2551.15
Subtracting 385 from 430 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 77, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 2551.155
If we take 385 away from 450, we end up 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 2551.155 with a remainder of 0.0065.
