72495332 divided by 438 
We want to divide 72495332 by 438.

Going ahead to step 1:
438 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 438

Moving on to step 2:
The number 438 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 438

On to step 3:
438 goes into 724 1 times with a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 438 from 724 leaves us with 286.
Append the next digit (9) from the dividend to 286 and continue with: 2869 / 438

Let's proceed to step 4:
438 goes into 2869 6 times with a remainder of 241.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 2628 from 2869 and we're left with 241.
Append the next digit (5) from the dividend to 241 and continue with: 2415 / 438

Going ahead to step 5:
When dividing 2415 by 438, we get 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 165.0
Deduct 2190 from 2415 and we're left with 225.
Bring next digit (3) of the dividend behind the 225 and repeat the process: 2253 / 438

Advancing to step 6:
2253 divided by 438 is 5 with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 1655.0
Subtract 2190 from 2253 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 438

Going ahead to step 7:
633 divided by 438 is 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 16551.0
Deduct 438 from 633 and we're left with 195.
Grab the next digit (2) from the dividend, add it to 195, then carry on: 1952 / 438

Moving on to step 8:
If we divide 1952 by 438, we get 4 and a remainder of 200.
Put 4 as the next digit of the answer. 
Result so far: 165514.0
Deduct 1752 from 1952 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 9:
If we divide 2000 by 438, we get 4 and a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 165514.4
Subtract 1752 from 2000 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 10:
438 goes into 2480 5 times with a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 165514.45
Subtract 2190 from 2480 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 11:
438 can be fit into 2900 6 times, resulting in a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 165514.456
Deduct 2628 from 2900 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 12:
When dividing 2720 by 438, we get 6 with a remainder of 92.
The next digit of our result is 6. 
Result so far: 165514.4566
Subtracting 2628 from 2720 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 165514.4566, with a leftover of 0.00092.
