39918484 divided by 819 
We want to figure out the number of times 39918484 can be divided by 819.

Step 1:
If we divide 3 by 819, we get 0 and 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.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 819

On to step 2:
819 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 819

Step 3:
399 divided by 819 is 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Grab the next digit (1) from the dividend, add it to 399, then carry on: 3991 / 819

Advancing to step 4:
3991 divided by 819 is 4 with a remainder of 715.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 715 after subtracting 3276 from 3991.
Bring next digit (8) of the dividend behind the 715 and repeat the process: 7158 / 819

Step 5:
The number 819 fits into 7158 8 times, leaving a remainder of 606.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 6552 away from 7158, we end up with 606.
Fetch the next digit (4) from the dividend, attach it to 606 and continue: 6064 / 819

Step 6:
6064 divided by 819 is 7 with a remainder of 331.
Put 7 as the next digit of the answer. 
Result so far: 487.0
Subtracting 5733 from 6064 leaves us with 331.
Take the next digit (8) from the dividend and append it to 331, then repeat: 3318 / 819

Step 7:
819 goes into 3318 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 4874.0
Deduct 3276 from 3318 and we're left with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 819

Moving on to step 8:
819 goes into 424 0 times with a remainder of 424.
Write down 0 as next digit of the result. 
Result so far: 48740.0
Deduct 0 from 424 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 9:
819 can be fit into 4240 5 times, resulting in a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 48740.5
The remainder is 145 after subtracting 4095 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
819 can be fit into 1450 1 times, resulting in a remainder of 631.
Record the quotient 1 as the next digit in the result. 
Result so far: 48740.51
Subtract 819 from 1450 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Let's proceed to step 11:
When dividing 6310 by 819, we get 7 with a remainder of 577.
Use 7 as the next digit of our solution. 
Result so far: 48740.517
The remainder is 577 after subtracting 5733 from 6310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 12:
819 goes into 5770 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 48740.5177
If we subtract 5733 from 5770, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 48740.5177 and a remainder of 0.00037.
