197790 ÷ 77 
Let's see how many times 77 fits into 197790.

On to step 1:
1 divided by 77 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 77

Advancing to step 2:
If we divide 19 by 77, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 77

Moving on to step 3:
197 divided by 77 is 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 154 from 197 leaves us with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 77

Advancing to step 4:
When dividing 437 by 77, we get 5 with a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 385 from 437 and we're left with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 77

Let's proceed to step 5:
529 divided by 77 is 6 with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 256.0
Subtracting 462 from 529 leaves us with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 77

Going ahead to step 6:
The number 77 fits into 670 8 times, leaving a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 2568.0
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
540 divided by 77 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 2568.7
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
When dividing 10 by 77, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2568.7
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
77 goes into 100 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 2568.701
If we take 77 away from 100, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
When dividing 230 by 77, we get 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 2568.7012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 2568.70129
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 12:
When dividing 670 by 77, we get 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 2568.701298
If we take 616 away from 670, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
The number 77 fits into 540 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2568.7012987
Deduct 539 from 540 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2568.7012987
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 2568.7012987 and a remainder of 1e-08.
