78501717 divided by 279 
We want to figure out the number of times 78501717 can be divided by 279.

Going ahead to step 1:
279 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 279

On to step 2:
279 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 279

Advancing to step 3:
When dividing 785 by 279, we get 2 with a remainder of 227.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 227 after subtracting 558 from 785.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 279

Going ahead to step 4:
When dividing 2270 by 279, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 38 after subtracting 2232 from 2270.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 279

On to step 5:
381 divided by 279 is 1 with a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtracting 279 from 381 leaves us with 102.
Include the next digit (7) from the dividend after 102, then repeat: 1027 / 279

Advancing to step 6:
If we divide 1027 by 279, we get 3 and a remainder of 190.
The next digit of our result is 3. 
Result so far: 2813.0
Subtracting 837 from 1027 leaves us with 190.
Bring next digit (1) of the dividend behind the 190 and repeat the process: 1901 / 279

Advancing to step 7:
If we divide 1901 by 279, we get 6 and a remainder of 227.
Put 6 as the next digit of the answer. 
Result so far: 28136.0
Subtract 1674 from 1901 to get 227.
Take the next digit (7) from the dividend and append it to 227, then repeat: 2277 / 279

Advancing to step 8:
When dividing 2277 by 279, we get 8 with a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 281368.0
Subtracting 2232 from 2277 leaves us 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.

Going ahead to step 9:
When dividing 450 by 279, we get 1 with a remainder of 171.
The next digit of our result is 1. 
Result so far: 281368.1
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.

Moving on to step 10:
When dividing 1710 by 279, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 281368.16
Subtracting 1674 from 1710 leaves us with 36.
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:
279 goes into 360 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 281368.161
The remainder is 81 after subtracting 279 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 12:
When dividing 810 by 279, we get 2 with a remainder of 252.
The next digit of our result is 2. 
Result so far: 281368.1612
If we subtract 558 from 810, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
279 can be fit into 2520 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 281368.16129
The remainder is 9 after subtracting 2511 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
If we divide 90 by 279, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 281368.16129
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
If we divide 900 by 279, we get 3 and a remainder of 63.
The next digit of our result is 3. 
Result so far: 281368.1612903
If we take 837 away from 900, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 16:
279 can be fit into 630 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 281368.16129032
Subtracting 558 from 630 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 281368.16129032 with a balance of 7.2e-08.
