We look at the division of 207999 by 78 
We're looking to find how many times 78 goes into 207999.

Going ahead to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 78

Let's proceed to step 2:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 78

Step 3:
The number 78 fits into 207 2 times, leaving a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 156 from 207 to get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 78

Advancing to step 4:
78 goes into 519 6 times with a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 468 from 519 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 78

Step 5:
519 divided by 78 is 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 266.0
If we subtract 468 from 519, we get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 78

On to step 6:
The number 78 fits into 519 6 times, leaving a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 2666.0
Subtract 468 from 519 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
The number 78 fits into 510 6 times, leaving a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 2666.6
If we subtract 468 from 510, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2666.65
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 2666.653
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
660 divided by 78 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2666.6538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
When dividing 360 by 78, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 2666.65384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 2666.653846
Deduct 468 from 480 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.

Moving on to step 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
The next digit of our result is 1. 
Result so far: 2666.6538461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
If we divide 420 by 78, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2666.65384615
The remainder is 30 after subtracting 390 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 2666.65384615 and a remainder of 3e-08.
