39212528 ÷ 903 
Let's see how many times 903 fits into 39212528.

On to step 1:
The number 903 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 903

Moving on to step 2:
903 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 903

Moving on to step 3:
903 can be fit into 392 0 times, resulting in a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 392, we get 392.
Bring next digit (1) of the dividend behind the 392 and repeat the process: 3921 / 903

Moving on to step 4:
If we divide 3921 by 903, we get 4 and a remainder of 309.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3612 from 3921, we get 309.
Take the next digit (2) from the dividend and append it to 309, then repeat: 3092 / 903

Moving on to step 5:
When dividing 3092 by 903, we get 3 with a remainder of 383.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 2709 from 3092, we get 383.
Include the next digit (5) from the dividend after 383, then repeat: 3835 / 903

Advancing to step 6:
If we divide 3835 by 903, we get 4 and a remainder of 223.
The next digit of our result is 4. 
Result so far: 434.0
Subtract 3612 from 3835 to get 223.
Bring next digit (2) of the dividend behind the 223 and repeat the process: 2232 / 903

Moving on to step 7:
The number 903 fits into 2232 2 times, leaving a remainder of 426.
Put 2 as the next digit of the answer. 
Result so far: 4342.0
If we take 1806 away from 2232, we end up with 426.
Fetch the next digit (8) from the dividend, attach it to 426 and continue: 4268 / 903

Moving on to step 8:
When dividing 4268 by 903, we get 4 with a remainder of 656.
The number 4 becomes the next digit in our result. 
Result so far: 43424.0
The remainder is 656 after subtracting 3612 from 4268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 9:
903 goes into 6560 7 times with a remainder of 239.
Put 7 as the next digit of the answer. 
Result so far: 43424.7
Subtracting 6321 from 6560 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 10:
If we divide 2390 by 903, we get 2 and a remainder of 584.
Write down 2 as next digit of the result. 
Result so far: 43424.72
Deduct 1806 from 2390 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 11:
903 goes into 5840 6 times with a remainder of 422.
Record the quotient 6 as the next digit in the result. 
Result so far: 43424.726
If we subtract 5418 from 5840, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 12:
903 can be fit into 4220 4 times, resulting in a remainder of 608.
The next digit of our result is 4. 
Result so far: 43424.7264
If we take 3612 away from 4220, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 13:
6080 divided by 903 is 6 with a remainder of 662.
Use 6 as the next digit of our solution. 
Result so far: 43424.72646
If we take 5418 away from 6080, we end up with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Step 14:
903 goes into 6620 7 times with a remainder of 299.
The number 7 becomes the next digit in our result. 
Result so far: 43424.726467
Subtracting 6321 from 6620 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 15:
The number 903 fits into 2990 3 times, leaving a remainder of 281.
The number 3 becomes the next digit in our result. 
Result so far: 43424.7264673
The remainder is 281 after subtracting 2709 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 16:
When dividing 2810 by 903, we get 3 with a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 43424.72646733
Subtracting 2709 from 2810 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 43424.72646733, with a leftover of 1.01e-07.
