12026 ÷ 78 
We want to figure out the number of times 12026 can be divided by 78.

Step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 78

Step 2:
78 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 78

On to step 3:
78 goes into 120 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 120 leaves us with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 78

Step 4:
When dividing 422 by 78, we get 5 with a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 390 away from 422, we end up with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 78

Going ahead to step 5:
When dividing 326 by 78, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 154.0
If we take 312 away from 326, we end up 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.

On to step 6:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 154.1
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 154.17
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.

Going ahead to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 154.179
Subtract 702 from 740 to 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.

Step 9:
78 goes into 380 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 154.1794
If we subtract 312 from 380, we 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.

On to step 10:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 154.17948
If we take 624 away from 680, we end up 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.

Moving on to step 11:
When dividing 560 by 78, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 154.179487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 78, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 154.1794871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 154.17948717
If we take 546 away from 620, we end up 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.

After the division, we end up with 154.17948717 and a remainder of 7.4e-08.
