Let's divide 39489378 by 819
We want to divide 39489378 by 819.

Going ahead to step 1:
The number 819 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 819

Going ahead to step 2:
When dividing 39 by 819, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 819

Let's proceed to step 3:
819 goes into 394 0 times with a remainder of 394.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Fetch the next digit (8) from the dividend, attach it to 394 and continue: 3948 / 819

Going ahead to step 4:
819 can be fit into 3948 4 times, resulting in a remainder of 672.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3276 away from 3948, we end up with 672.
Append the next digit (9) from the dividend to 672 and continue with: 6729 / 819

Let's proceed to step 5:
819 goes into 6729 8 times with a remainder of 177.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 6552 from 6729 leaves us with 177.
Take the next digit (3) from the dividend and append it to 177, then repeat: 1773 / 819

On to step 6:
If we divide 1773 by 819, we get 2 and a remainder of 135.
The next digit of our result is 2. 
Result so far: 482.0
Subtracting 1638 from 1773 leaves us with 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 819

Advancing to step 7:
819 can be fit into 1357 1 times, resulting in a remainder of 538.
Use 1 as the next digit of our solution. 
Result so far: 4821.0
If we subtract 819 from 1357, we get 538.
Include the next digit (8) from the dividend after 538, then repeat: 5388 / 819

Let's proceed to step 8:
5388 divided by 819 is 6 with a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 48216.0
Deduct 4914 from 5388 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 9:
819 goes into 4740 5 times with a remainder of 645.
Record the quotient 5 as the next digit in the result. 
Result so far: 48216.5
Subtract 4095 from 4740 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 10:
819 goes into 6450 7 times with a remainder of 717.
Use 7 as the next digit of our solution. 
Result so far: 48216.57
If we take 5733 away from 6450, we end up with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Step 11:
When dividing 7170 by 819, we get 8 with a remainder of 618.
Write down 8 as next digit of the result. 
Result so far: 48216.578
Subtract 6552 from 7170 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 12:
When dividing 6180 by 819, we get 7 with a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 48216.5787
Deduct 5733 from 6180 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 13:
If we divide 4470 by 819, we get 5 and a remainder of 375.
The next digit of our result is 5. 
Result so far: 48216.57875
If we subtract 4095 from 4470, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 14:
When dividing 3750 by 819, we get 4 with a remainder of 474.
Use 4 as the next digit of our solution. 
Result so far: 48216.578754
If we subtract 3276 from 3750, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 15:
The number 819 fits into 4740 5 times, leaving a remainder of 645.
The next digit of our result is 5. 
Result so far: 48216.5787545
If we take 4095 away from 4740, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 16:
When dividing 6450 by 819, we get 7 with a remainder of 717.
Put 7 as the next digit of the answer. 
Result so far: 48216.57875457
Deduct 5733 from 6450 and we're left with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

After the division, we end up with 48216.57875457 and a remainder of 7.17e-07.
