We look at the division of 19388473 by 903 
Our goal is to divide 19388473 by 903.

Moving on to step 1:
If we divide 1 by 903, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 903

Advancing to step 2:
19 divided by 903 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 903

Going ahead to step 3:
903 can be fit into 193 0 times, resulting in a remainder of 193.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 193 to get 193.
Append the next digit (8) from the dividend to 193 and continue with: 1938 / 903

Advancing to step 4:
When dividing 1938 by 903, we get 2 with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1806 from 1938, we get 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 903

Let's proceed to step 5:
903 can be fit into 1328 1 times, resulting in a remainder of 425.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 903 from 1328, we get 425.
Take the next digit (4) from the dividend and append it to 425, then repeat: 4254 / 903

Moving on to step 6:
The number 903 fits into 4254 4 times, leaving a remainder of 642.
Write down 4 as next digit of the result. 
Result so far: 214.0
If we subtract 3612 from 4254, we get 642.
Bring next digit (7) of the dividend behind the 642 and repeat the process: 6427 / 903

Step 7:
If we divide 6427 by 903, we get 7 and a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 2147.0
If we take 6321 away from 6427, we end up with 106.
Append the next digit (3) from the dividend to 106 and continue with: 1063 / 903

Going ahead to step 8:
903 goes into 1063 1 times with a remainder of 160.
The number 1 becomes the next digit in our result. 
Result so far: 21471.0
Deduct 903 from 1063 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
903 goes into 1600 1 times with a remainder of 697.
Use 1 as the next digit of our solution. 
Result so far: 21471.1
If we take 903 away from 1600, we end up with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Let's proceed to step 10:
If we divide 6970 by 903, we get 7 and a remainder of 649.
Record the quotient 7 as the next digit in the result. 
Result so far: 21471.17
If we subtract 6321 from 6970, we get 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Going ahead to step 11:
903 can be fit into 6490 7 times, resulting in a remainder of 169.
The number 7 becomes the next digit in our result. 
Result so far: 21471.177
If we take 6321 away from 6490, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The final outcome is 21471.177, with a leftover of 0.0169.
