We look at the division of 75191409 by 903 
We're looking to find how many times 903 goes into 75191409.

Moving on to step 1:
7 divided by 903 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 903

Going ahead to step 2:
If we divide 75 by 903, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 903

Going ahead to step 3:
When dividing 751 by 903, we get 0 with a remainder of 751.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 751 and we're left with 751.
Take the next digit (9) from the dividend and append it to 751, then repeat: 7519 / 903

Moving on to step 4:
7519 divided by 903 is 8 with a remainder of 295.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7224 from 7519 and we're left with 295.
Include the next digit (1) from the dividend after 295, then repeat: 2951 / 903

Advancing to step 5:
2951 divided by 903 is 3 with a remainder of 242.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we subtract 2709 from 2951, we get 242.
Fetch the next digit (4) from the dividend, attach it to 242 and continue: 2424 / 903

Moving on to step 6:
If we divide 2424 by 903, we get 2 and a remainder of 618.
Record the quotient 2 as the next digit in the result. 
Result so far: 832.0
Subtracting 1806 from 2424 leaves us with 618.
Take the next digit (0) from the dividend and append it to 618, then repeat: 6180 / 903

Advancing to step 7:
903 goes into 6180 6 times with a remainder of 762.
The number 6 becomes the next digit in our result. 
Result so far: 8326.0
If we take 5418 away from 6180, we end up with 762.
Include the next digit (9) from the dividend after 762, then repeat: 7629 / 903

On to step 8:
If we divide 7629 by 903, we get 8 and a remainder of 405.
Use 8 as the next digit of our solution. 
Result so far: 83268.0
Subtract 7224 from 7629 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 9:
903 goes into 4050 4 times with a remainder of 438.
Record the quotient 4 as the next digit in the result. 
Result so far: 83268.4
Subtract 3612 from 4050 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 10:
When dividing 4380 by 903, we get 4 with a remainder of 768.
The number 4 becomes the next digit in our result. 
Result so far: 83268.44
If we take 3612 away from 4380, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

In conclusion, the division gives 83268.44 with a balance of 0.768.
