42064604 ÷ 393 
Let's see how many times 393 fits into 42064604.

Step 1:
If we divide 4 by 393, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 393

Advancing to step 2:
42 divided by 393 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 393

On to step 3:
420 divided by 393 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 27 after subtracting 393 from 420.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 393

On to step 4:
When dividing 276 by 393, we get 0 with a remainder of 276.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 276 and we're left with 276.
Append the next digit (4) from the dividend to 276 and continue with: 2764 / 393

Advancing to step 5:
If we divide 2764 by 393, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 107.0
The remainder is 13 after subtracting 2751 from 2764.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 393

Let's proceed to step 6:
When dividing 136 by 393, we get 0 with a remainder of 136.
Write down 0 as next digit of the result. 
Result so far: 1070.0
Subtracting 0 from 136 leaves us with 136.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 393

Going ahead to step 7:
1360 divided by 393 is 3 with a remainder of 181.
The number 3 becomes the next digit in our result. 
Result so far: 10703.0
Subtract 1179 from 1360 to get 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 393

Moving on to step 8:
When dividing 1814 by 393, we get 4 with a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 107034.0
Deduct 1572 from 1814 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 9:
393 goes into 2420 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 107034.6
Deduct 2358 from 2420 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
620 divided by 393 is 1 with a remainder of 227.
Use 1 as the next digit of our solution. 
Result so far: 107034.61
Deduct 393 from 620 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 11:
393 goes into 2270 5 times with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 107034.615
If we subtract 1965 from 2270, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 12:
If we divide 3050 by 393, we get 7 and a remainder of 299.
Write down 7 as next digit of the result. 
Result so far: 107034.6157
If we take 2751 away from 3050, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 13:
When dividing 2990 by 393, we get 7 with a remainder of 239.
The number 7 becomes the next digit in our result. 
Result so far: 107034.61577
Subtracting 2751 from 2990 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The quotient of the division is 107034.61577, and the remainder is 0.000239.
