We look at the division of 86948570 by 279 
We want to figure out the number of times 86948570 can be divided by 279.

On to step 1:
If we divide 8 by 279, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 279

Moving on to step 2:
279 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 279

Going ahead to step 3:
279 can be fit into 869 3 times, resulting in a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 837 from 869 leaves us with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 279

On to step 4:
279 goes into 324 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 279 from 324, we get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 279

Going ahead to step 5:
When dividing 458 by 279, we get 1 with a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
If we take 279 away from 458, we end up with 179.
Fetch the next digit (5) from the dividend, attach it to 179 and continue: 1795 / 279

On to step 6:
279 goes into 1795 6 times with a remainder of 121.
Write down 6 as next digit of the result. 
Result so far: 3116.0
If we subtract 1674 from 1795, we get 121.
Fetch the next digit (7) from the dividend, attach it to 121 and continue: 1217 / 279

Advancing to step 7:
1217 divided by 279 is 4 with a remainder of 101.
Record the quotient 4 as the next digit in the result. 
Result so far: 31164.0
Subtracting 1116 from 1217 leaves us with 101.
Append the next digit (0) from the dividend to 101 and continue with: 1010 / 279

Step 8:
When dividing 1010 by 279, we get 3 with a remainder of 173.
The next digit of our result is 3. 
Result so far: 311643.0
If we take 837 away from 1010, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 9:
When dividing 1730 by 279, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 311643.6
The remainder is 56 after subtracting 1674 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
When dividing 560 by 279, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 311643.62
The remainder is 2 after subtracting 558 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
When dividing 20 by 279, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 311643.62
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 279 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 311643.62
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 311643.62 and a remainder of 0.002.
