39442856 ÷ 578 
We want to figure out the number of times 39442856 can be divided by 578.

Going ahead to step 1:
578 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 578

On to step 2:
39 divided by 578 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 578

Going ahead to step 3:
578 goes into 394 0 times with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 394 leaves us with 394.
Include the next digit (4) from the dividend after 394, then repeat: 3944 / 578

Step 4:
578 goes into 3944 6 times with a remainder of 476.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 3468 away from 3944, we end up with 476.
Bring next digit (2) of the dividend behind the 476 and repeat the process: 4762 / 578

Going ahead to step 5:
The number 578 fits into 4762 8 times, leaving a remainder of 138.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 138 after subtracting 4624 from 4762.
Include the next digit (8) from the dividend after 138, then repeat: 1388 / 578

Advancing to step 6:
If we divide 1388 by 578, we get 2 and a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 682.0
If we take 1156 away from 1388, we end up with 232.
Grab the next digit (5) from the dividend, add it to 232, then carry on: 2325 / 578

On to step 7:
When dividing 2325 by 578, we get 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 6824.0
The remainder is 13 after subtracting 2312 from 2325.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 578

Advancing to step 8:
578 can be fit into 136 0 times, resulting in a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 68240.0
Deduct 0 from 136 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
578 goes into 1360 2 times with a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 68240.2
Subtract 1156 from 1360 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 10:
If we divide 2040 by 578, we get 3 and a remainder of 306.
The next digit of our result is 3. 
Result so far: 68240.23
If we take 1734 away from 2040, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 11:
3060 divided by 578 is 5 with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 68240.235
Deduct 2890 from 3060 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 12:
578 can be fit into 1700 2 times, resulting in a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 68240.2352
Subtract 1156 from 1700 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 13:
The number 578 fits into 5440 9 times, leaving a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 68240.23529
Subtracting 5202 from 5440 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 14:
If we divide 2380 by 578, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 68240.235294
Deduct 2312 from 2380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 15:
578 can be fit into 680 1 times, resulting in a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 68240.2352941
Subtract 578 from 680 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 16:
1020 divided by 578 is 1 with a remainder of 442.
Write down 1 as next digit of the result. 
Result so far: 68240.23529411
Subtracting 578 from 1020 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

The quotient of the division is 68240.23529411, and the remainder is 4.42e-07.
