45302151 ÷ 72 
We're looking to find how many times 72 goes into 45302151.

On to step 1:
When dividing 4 by 72, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 72

Moving on to step 2:
The number 72 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 72

Going ahead to step 3:
72 goes into 453 6 times with a remainder of 21.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 432 from 453, we get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 72

Moving on to step 4:
If we divide 210 by 72, we get 2 and a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
The remainder is 66 after subtracting 144 from 210.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 72

Step 5:
If we divide 662 by 72, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 629.0
If we take 648 away from 662, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 72

Let's proceed to step 6:
If we divide 141 by 72, we get 1 and a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 6291.0
The remainder is 69 after subtracting 72 from 141.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 72

Step 7:
72 can be fit into 695 9 times, resulting in a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 62919.0
Subtracting 648 from 695 leaves us with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 72

Moving on to step 8:
The number 72 fits into 471 6 times, leaving a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 629196.0
The remainder is 39 after subtracting 432 from 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
When dividing 390 by 72, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 629196.5
Subtracting 360 from 390 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
72 can be fit into 300 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 629196.54
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 72, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 629196.541
Subtracting 72 from 120 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 629196.5416
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 629196.54166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 629196.54166 and a remainder of 4.8e-05.
