7 divided by 294 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 294

On to step 2:
When dividing 78 by 294, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 294

Let's proceed to step 3:
294 can be fit into 784 2 times, resulting in a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 588 from 784 leaves us with 196.
Include the next digit (0) from the dividend after 196, then repeat: 1960 / 294

Going ahead to step 4:
294 can be fit into 1960 6 times, resulting in a remainder of 196.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 1764 from 1960 leaves us with 196.
Fetch the next digit (7) from the dividend, attach it to 196 and continue: 1967 / 294

Advancing to step 5:
When dividing 1967 by 294, we get 6 with a remainder of 203.
Put 6 as the next digit of the answer. 
Result so far: 266.0
The remainder is 203 after subtracting 1764 from 1967.
Take the next digit (4) from the dividend and append it to 203, then repeat: 2034 / 294

On to step 6:
294 goes into 2034 6 times with a remainder of 270.
The next digit of our result is 6. 
Result so far: 2666.0
Deduct 1764 from 2034 and we're left with 270.
Take the next digit (2) from the dividend and append it to 270, then repeat: 2702 / 294

Going ahead to step 7:
294 can be fit into 2702 9 times, resulting in a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 26669.0
The remainder is 56 after subtracting 2646 from 2702.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 294

Advancing to step 8:
The number 294 fits into 563 1 times, leaving a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 266691.0
If we take 294 away from 563, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 9:
294 goes into 2690 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 266691.9
The remainder is 44 after subtracting 2646 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
294 goes into 440 1 times with a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 266691.91
The remainder is 146 after subtracting 294 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 11:
1460 divided by 294 is 4 with a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 266691.914
The remainder is 284 after subtracting 1176 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 12:
If we divide 2840 by 294, we get 9 and a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 266691.9149
Deduct 2646 from 2840 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 13:
1940 divided by 294 is 6 with a remainder of 176.
The next digit of our result is 6. 
Result so far: 266691.91496
Subtracting 1764 from 1940 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
1760 divided by 294 is 5 with a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 266691.914965
If we subtract 1470 from 1760, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 15:
When dividing 2900 by 294, we get 9 with a remainder of 254.
Use 9 as the next digit of our solution. 
Result so far: 266691.9149659
If we take 2646 away from 2900, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 16:
When dividing 2540 by 294, we get 8 with a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 266691.91496598
If we take 2352 away from 2540, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Our division results in 266691.91496598 with a remaining 1.88e-07.
