1556 ÷ 78 
We want to divide 1556 by 78.

Let's proceed to step 1:
78 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 78

Step 2:
15 divided by 78 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 78

Advancing to step 3:
78 goes into 155 1 times with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 78 from 155 to get 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 78

On to step 4:
776 divided by 78 is 9 with a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 702 from 776 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 5:
The number 78 fits into 740 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 19.9
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 6:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 19.94
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
78 goes into 680 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 19.948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
When dividing 560 by 78, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 19.9487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 78, we get 1 and a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 19.94871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
620 divided by 78 is 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 19.948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
740 divided by 78 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.9487179
If we subtract 702 from 740, we 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 12:
When dividing 380 by 78, we get 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 19.94871794
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 19.94871794 and a remainder of 6.8e-08.
