We look at the division of 39963450 by 844 
We want to figure out the number of times 39963450 can be divided by 844.

Going ahead to step 1:
When dividing 3 by 844, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 844

Let's proceed to step 2:
If we divide 39 by 844, we get 0 and 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.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 844

Going ahead to step 3:
844 goes into 399 0 times with a remainder of 399.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 399 after subtracting 0 from 399.
Include the next digit (6) from the dividend after 399, then repeat: 3996 / 844

Moving on to step 4:
When dividing 3996 by 844, we get 4 with a remainder of 620.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3376 from 3996 and we're left with 620.
Grab the next digit (3) from the dividend, add it to 620, then carry on: 6203 / 844

Advancing to step 5:
6203 divided by 844 is 7 with a remainder of 295.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 5908 from 6203 leaves us with 295.
Append the next digit (4) from the dividend to 295 and continue with: 2954 / 844

Step 6:
If we divide 2954 by 844, we get 3 and a remainder of 422.
The next digit of our result is 3. 
Result so far: 473.0
The remainder is 422 after subtracting 2532 from 2954.
Append the next digit (5) from the dividend to 422 and continue with: 4225 / 844

Step 7:
When dividing 4225 by 844, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4735.0
Deduct 4220 from 4225 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 844

Advancing to step 8:
844 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 47350.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
When dividing 500 by 844, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 47350.0
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 10:
5000 divided by 844 is 5 with a remainder of 780.
Put 5 as the next digit of the answer. 
Result so far: 47350.05
If we subtract 4220 from 5000, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 11:
7800 divided by 844 is 9 with a remainder of 204.
Put 9 as the next digit of the answer. 
Result so far: 47350.059
If we take 7596 away from 7800, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 12:
When dividing 2040 by 844, we get 2 with a remainder of 352.
The next digit of our result is 2. 
Result so far: 47350.0592
If we subtract 1688 from 2040, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 13:
The number 844 fits into 3520 4 times, leaving a remainder of 144.
The next digit of our result is 4. 
Result so far: 47350.05924
If we take 3376 away from 3520, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 14:
When dividing 1440 by 844, we get 1 with a remainder of 596.
Put 1 as the next digit of the answer. 
Result so far: 47350.059241
The remainder is 596 after subtracting 844 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 15:
5960 divided by 844 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 47350.0592417
Subtract 5908 from 5960 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 16:
844 can be fit into 520 0 times, resulting in a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 47350.0592417
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 47350.0592417 with a remaining 5.2e-07.
