39396314 ÷ 903 
We're looking to find how many times 903 goes into 39396314.

Step 1:
3 divided by 903 is 0 with a remainder of 3.
The number 0 becomes the next digit in our 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 / 903

Going ahead to step 2:
If we divide 39 by 903, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 903

Going ahead to step 3:
The number 903 fits into 393 0 times, leaving a remainder of 393.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Include the next digit (9) from the dividend after 393, then repeat: 3939 / 903

Step 4:
When dividing 3939 by 903, we get 4 with a remainder of 327.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3612 away from 3939, we end up with 327.
Fetch the next digit (6) from the dividend, attach it to 327 and continue: 3276 / 903

Advancing to step 5:
3276 divided by 903 is 3 with a remainder of 567.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 2709 from 3276 and we're left with 567.
Grab the next digit (3) from the dividend, add it to 567, then carry on: 5673 / 903

Step 6:
If we divide 5673 by 903, we get 6 and a remainder of 255.
The number 6 becomes the next digit in our result. 
Result so far: 436.0
Deduct 5418 from 5673 and we're left with 255.
Grab the next digit (1) from the dividend, add it to 255, then carry on: 2551 / 903

On to step 7:
When dividing 2551 by 903, we get 2 with a remainder of 745.
Write down 2 as next digit of the result. 
Result so far: 4362.0
Subtracting 1806 from 2551 leaves us with 745.
Include the next digit (4) from the dividend after 745, then repeat: 7454 / 903

Moving on to step 8:
When dividing 7454 by 903, we get 8 with a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 43628.0
The remainder is 230 after subtracting 7224 from 7454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 9:
When dividing 2300 by 903, we get 2 with a remainder of 494.
The next digit of our result is 2. 
Result so far: 43628.2
The remainder is 494 after subtracting 1806 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 10:
The number 903 fits into 4940 5 times, leaving a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 43628.25
The remainder is 425 after subtracting 4515 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 11:
4250 divided by 903 is 4 with a remainder of 638.
Write down 4 as next digit of the result. 
Result so far: 43628.254
Subtract 3612 from 4250 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Let's proceed to step 12:
903 can be fit into 6380 7 times, resulting in a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 43628.2547
Subtract 6321 from 6380 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 13:
903 can be fit into 590 0 times, resulting in a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 43628.2547
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 14:
903 goes into 5900 6 times with a remainder of 482.
Use 6 as the next digit of our solution. 
Result so far: 43628.254706
Subtracting 5418 from 5900 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 15:
903 can be fit into 4820 5 times, resulting in a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 43628.2547065
The remainder is 305 after subtracting 4515 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 16:
When dividing 3050 by 903, we get 3 with a remainder of 341.
Record the quotient 3 as the next digit in the result. 
Result so far: 43628.25470653
Subtracting 2709 from 3050 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

The final outcome is 43628.25470653, with a leftover of 3.41e-07.
