Let's divide 3920338 by 903
We want to figure out the number of times 3920338 can be divided by 903.

Advancing to step 1:
When dividing 3 by 903, we get 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.
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.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 903

On to step 3:
392 divided by 903 is 0 with a remainder of 392.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 392 and we're left with 392.
Append the next digit (0) from the dividend to 392 and continue with: 3920 / 903

On to step 4:
3920 divided by 903 is 4 with a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 308 after subtracting 3612 from 3920.
Take the next digit (3) from the dividend and append it to 308, then repeat: 3083 / 903

Moving on to step 5:
If we divide 3083 by 903, we get 3 and a remainder of 374.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 2709 from 3083 to get 374.
Bring next digit (3) of the dividend behind the 374 and repeat the process: 3743 / 903

Let's proceed to step 6:
If we divide 3743 by 903, we get 4 and a remainder of 131.
Write down 4 as next digit of the result. 
Result so far: 434.0
Subtracting 3612 from 3743 leaves us with 131.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 903

Step 7:
1318 divided by 903 is 1 with a remainder of 415.
The next digit of our result is 1. 
Result so far: 4341.0
Deduct 903 from 1318 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 8:
The number 903 fits into 4150 4 times, leaving a remainder of 538.
The number 4 becomes the next digit in our result. 
Result so far: 4341.4
Subtract 3612 from 4150 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 9:
903 goes into 5380 5 times with a remainder of 865.
The number 5 becomes the next digit in our result. 
Result so far: 4341.45
The remainder is 865 after subtracting 4515 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Let's proceed to step 10:
903 can be fit into 8650 9 times, resulting in a remainder of 523.
The number 9 becomes the next digit in our result. 
Result so far: 4341.459
Deduct 8127 from 8650 and we're left with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 11:
The number 903 fits into 5230 5 times, leaving a remainder of 715.
The number 5 becomes the next digit in our result. 
Result so far: 4341.4595
The remainder is 715 after subtracting 4515 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Let's proceed to step 12:
If we divide 7150 by 903, we get 7 and a remainder of 829.
The number 7 becomes the next digit in our result. 
Result so far: 4341.45957
The remainder is 829 after subtracting 6321 from 7150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Moving on to step 13:
If we divide 8290 by 903, we get 9 and a remainder of 163.
The next digit of our result is 9. 
Result so far: 4341.459579
Deduct 8127 from 8290 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 14:
1630 divided by 903 is 1 with a remainder of 727.
Put 1 as the next digit of the answer. 
Result so far: 4341.4595791
If we subtract 903 from 1630, we get 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Moving on to step 15:
7270 divided by 903 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 4341.45957918
The remainder is 46 after subtracting 7224 from 7270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 4341.45957918, with a leftover of 4.6e-08.
