72903307 divided by 207 
We want to figure out the number of times 72903307 can be divided by 207.

Step 1:
When dividing 7 by 207, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 207

Step 2:
72 divided by 207 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 207

Moving on to step 3:
207 goes into 729 3 times with a remainder of 108.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 108 after subtracting 621 from 729.
Take the next digit (0) from the dividend and append it to 108, then repeat: 1080 / 207

Let's proceed to step 4:
The number 207 fits into 1080 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 1035 from 1080 to get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 207

Step 5:
The number 207 fits into 453 2 times, leaving a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
If we subtract 414 from 453, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 207

Let's proceed to step 6:
If we divide 393 by 207, we get 1 and a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 3521.0
If we subtract 207 from 393, we get 186.
Append the next digit (0) from the dividend to 186 and continue with: 1860 / 207

Let's proceed to step 7:
207 can be fit into 1860 8 times, resulting in a remainder of 204.
The next digit of our result is 8. 
Result so far: 35218.0
Subtract 1656 from 1860 to get 204.
Bring next digit (7) of the dividend behind the 204 and repeat the process: 2047 / 207

On to step 8:
207 can be fit into 2047 9 times, resulting in a remainder of 184.
Write down 9 as next digit of the result. 
Result so far: 352189.0
Subtracting 1863 from 2047 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 9:
If we divide 1840 by 207, we get 8 and a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 352189.8
Subtract 1656 from 1840 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
207 goes into 1840 8 times with a remainder of 184.
The next digit of our result is 8. 
Result so far: 352189.88
The remainder is 184 after subtracting 1656 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 352189.88, with a leftover of 0.184.
