79725885 ÷ 279 
We want to divide 79725885 by 279.

Step 1:
The number 279 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 279

Moving on to step 2:
If we divide 79 by 279, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 279

Let's proceed to step 3:
When dividing 797 by 279, we get 2 with a remainder of 239.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 558 from 797 to get 239.
Bring next digit (2) of the dividend behind the 239 and repeat the process: 2392 / 279

Moving on to step 4:
2392 divided by 279 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 2232 away from 2392, we end up with 160.
Fetch the next digit (5) from the dividend, attach it to 160 and continue: 1605 / 279

Going ahead to step 5:
279 goes into 1605 5 times with a remainder of 210.
The next digit of our result is 5. 
Result so far: 285.0
The remainder is 210 after subtracting 1395 from 1605.
Bring next digit (8) of the dividend behind the 210 and repeat the process: 2108 / 279

Step 6:
279 goes into 2108 7 times with a remainder of 155.
The next digit of our result is 7. 
Result so far: 2857.0
Deduct 1953 from 2108 and we're left with 155.
Append the next digit (8) from the dividend to 155 and continue with: 1558 / 279

Moving on to step 7:
If we divide 1558 by 279, we get 5 and a remainder of 163.
The number 5 becomes the next digit in our result. 
Result so far: 28575.0
If we subtract 1395 from 1558, we get 163.
Include the next digit (5) from the dividend after 163, then repeat: 1635 / 279

On to step 8:
279 can be fit into 1635 5 times, resulting in a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 285755.0
If we take 1395 away from 1635, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 9:
279 can be fit into 2400 8 times, resulting in a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 285755.8
The remainder is 168 after subtracting 2232 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
279 can be fit into 1680 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 285755.86
If we take 1674 away from 1680, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 279, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 285755.86
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
When dividing 600 by 279, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 285755.8602
If we take 558 away from 600, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
420 divided by 279 is 1 with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 285755.86021
If we take 279 away from 420, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 14:
279 can be fit into 1410 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 285755.860215
If we take 1395 away from 1410, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
The number 279 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 285755.860215
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 16:
1500 divided by 279 is 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 285755.86021505
Subtract 1395 from 1500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 285755.86021505, with a leftover of 1.05e-07.
