228123 ÷ 78 
Let's see how many times 78 fits into 228123.

Step 1:
2 divided by 78 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 78

Advancing to step 2:
The number 78 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 78

Advancing to step 3:
78 goes into 228 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 156 from 228 to get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 78

Step 4:
The number 78 fits into 721 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 29.0
If we take 702 away from 721, we end up with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 78

On to step 5:
192 divided by 78 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
Subtract 156 from 192 to get 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 78

Advancing to step 6:
78 can be fit into 363 4 times, resulting in a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 2924.0
Subtract 312 from 363 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.

Advancing to step 7:
If we divide 510 by 78, we get 6 and a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 2924.6
The remainder is 42 after subtracting 468 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
78 can be fit into 420 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 2924.65
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:
When dividing 300 by 78, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 2924.653
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
78 goes into 660 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2924.6538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 2924.65384
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.

Advancing to step 12:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 2924.653846
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.

Going ahead to step 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 2924.6538461
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.

Step 14:
When dividing 420 by 78, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2924.65384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 2924.65384615 with a remaining 3e-08.
