152720 ÷ 78 
Let's see how many times 78 fits into 152720.

Going ahead to step 1:
1 divided by 78 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 78

Going ahead to step 2:
The number 78 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 78

On to step 3:
152 divided by 78 is 1 with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 78 away from 152, we end up with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 78

Moving on to step 4:
78 can be fit into 747 9 times, resulting in a remainder of 45.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 702 from 747 and we're left with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 78

On to step 5:
78 can be fit into 452 5 times, resulting in a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 195.0
If we subtract 390 from 452, we get 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 78

On to step 6:
The number 78 fits into 620 7 times, leaving a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 1957.0
Subtracting 546 from 620 leaves us 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.

On to step 7:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 1957.9
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.

Advancing to step 8:
The number 78 fits into 380 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 1957.94
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 1957.948
Deduct 624 from 680 and we're left 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 10:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 1957.9487
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.

Step 11:
78 goes into 140 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1957.94871
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 12:
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: 1957.948717
Subtracting 546 from 620 leaves us 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.

Let's proceed to step 13:
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: 1957.9487179
If we take 702 away from 740, we end up 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.

Step 14:
If we divide 380 by 78, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 1957.94871794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 1957.94871794 with a remaining 6.8e-08.
