78563493 divided by 279 
Let's see how many times 279 fits into 78563493.

On to step 1:
The number 279 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 279

Moving on to step 2:
When dividing 78 by 279, 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.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 279

On to step 3:
When dividing 785 by 279, we get 2 with a remainder of 227.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 558 from 785 and we're left with 227.
Grab the next digit (6) from the dividend, add it to 227, then carry on: 2276 / 279

Let's proceed to step 4:
279 goes into 2276 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 2232 from 2276 and we're left with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 279

Going ahead to step 5:
279 can be fit into 443 1 times, resulting in a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
If we subtract 279 from 443, we get 164.
Include the next digit (4) from the dividend after 164, then repeat: 1644 / 279

Moving on to step 6:
279 goes into 1644 5 times with a remainder of 249.
Use 5 as the next digit of our solution. 
Result so far: 2815.0
Subtracting 1395 from 1644 leaves us with 249.
Append the next digit (9) from the dividend to 249 and continue with: 2499 / 279

Step 7:
If we divide 2499 by 279, we get 8 and a remainder of 267.
Write down 8 as next digit of the result. 
Result so far: 28158.0
If we subtract 2232 from 2499, we get 267.
Grab the next digit (3) from the dividend, add it to 267, then carry on: 2673 / 279

Moving on to step 8:
279 goes into 2673 9 times with a remainder of 162.
Record the quotient 9 as the next digit in the result. 
Result so far: 281589.0
If we take 2511 away from 2673, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
The number 279 fits into 1620 5 times, leaving a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 281589.5
If we subtract 1395 from 1620, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 10:
When dividing 2250 by 279, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 281589.58
Deduct 2232 from 2250 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
If we divide 180 by 279, we get 0 and a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 281589.58
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
1800 divided by 279 is 6 with a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 281589.5806
Deduct 1674 from 1800 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 13:
279 goes into 1260 4 times with a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 281589.58064
Subtracting 1116 from 1260 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 14:
1440 divided by 279 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 281589.580645
Deduct 1395 from 1440 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 15:
The number 279 fits into 450 1 times, leaving a remainder of 171.
The number 1 becomes the next digit in our result. 
Result so far: 281589.5806451
Subtracting 279 from 450 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 16:
When dividing 1710 by 279, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 281589.58064516
The remainder is 36 after subtracting 1674 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 281589.58064516 with a remainder of 3.6e-08.
