78439636 divided by 386 
We're looking to find how many times 386 goes into 78439636.

Advancing to step 1:
386 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 386

Going ahead to step 2:
When dividing 78 by 386, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 386

Let's proceed to step 3:
784 divided by 386 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 772 from 784, we get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 386

On to step 4:
386 goes into 123 0 times with a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 123 and we're left with 123.
Take the next digit (9) from the dividend and append it to 123, then repeat: 1239 / 386

Step 5:
If we divide 1239 by 386, we get 3 and a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Deduct 1158 from 1239 and we're left with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 386

Step 6:
386 goes into 816 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2032.0
Subtracting 772 from 816 leaves us with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 386

On to step 7:
443 divided by 386 is 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 20321.0
Subtracting 386 from 443 leaves us with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 386

Step 8:
The number 386 fits into 576 1 times, leaving a remainder of 190.
Use 1 as the next digit of our solution. 
Result so far: 203211.0
If we take 386 away from 576, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 9:
When dividing 1900 by 386, we get 4 with a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 203211.4
Subtract 1544 from 1900 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
The number 386 fits into 3560 9 times, leaving a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 203211.49
The remainder is 86 after subtracting 3474 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 11:
If we divide 860 by 386, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 203211.492
The remainder is 88 after subtracting 772 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
386 goes into 880 2 times with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 203211.4922
If we subtract 772 from 880, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 203211.4922, with a leftover of 0.00108.
