We look at the division of 87225073 by 903 
We want to figure out the number of times 87225073 can be divided by 903.

Let's proceed to step 1:
If we divide 8 by 903, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 903

Moving on to step 2:
903 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 903

On to step 3:
872 divided by 903 is 0 with a remainder of 872.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 872, we get 872.
Bring next digit (2) of the dividend behind the 872 and repeat the process: 8722 / 903

Let's proceed to step 4:
If we divide 8722 by 903, we get 9 and a remainder of 595.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 595 after subtracting 8127 from 8722.
Take the next digit (5) from the dividend and append it to 595, then repeat: 5955 / 903

Step 5:
903 can be fit into 5955 6 times, resulting in a remainder of 537.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we subtract 5418 from 5955, we get 537.
Append the next digit (0) from the dividend to 537 and continue with: 5370 / 903

Moving on to step 6:
If we divide 5370 by 903, we get 5 and a remainder of 855.
The next digit of our result is 5. 
Result so far: 965.0
If we take 4515 away from 5370, we end up with 855.
Append the next digit (7) from the dividend to 855 and continue with: 8557 / 903

Let's proceed to step 7:
903 can be fit into 8557 9 times, resulting in a remainder of 430.
Use 9 as the next digit of our solution. 
Result so far: 9659.0
The remainder is 430 after subtracting 8127 from 8557.
Grab the next digit (3) from the dividend, add it to 430, then carry on: 4303 / 903

Let's proceed to step 8:
903 can be fit into 4303 4 times, resulting in a remainder of 691.
The next digit of our result is 4. 
Result so far: 96594.0
Subtracting 3612 from 4303 leaves us with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

On to step 9:
If we divide 6910 by 903, we get 7 and a remainder of 589.
Record the quotient 7 as the next digit in the result. 
Result so far: 96594.7
The remainder is 589 after subtracting 6321 from 6910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 10:
If we divide 5890 by 903, we get 6 and a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 96594.76
If we subtract 5418 from 5890, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 11:
The number 903 fits into 4720 5 times, leaving a remainder of 205.
The next digit of our result is 5. 
Result so far: 96594.765
The remainder is 205 after subtracting 4515 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 12:
903 can be fit into 2050 2 times, resulting in a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 96594.7652
Subtracting 1806 from 2050 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 13:
When dividing 2440 by 903, we get 2 with a remainder of 634.
Record the quotient 2 as the next digit in the result. 
Result so far: 96594.76522
Subtracting 1806 from 2440 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

The final outcome is 96594.76522, with a leftover of 0.000634.
