We're dividing 45908920 by 72 
We want to figure out the number of times 45908920 can be divided by 72.

Moving on to step 1:
When dividing 4 by 72, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 72

Let's proceed to step 2:
If we divide 45 by 72, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 72

Step 3:
72 goes into 459 6 times with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 432 from 459 leaves us with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 72

On to step 4:
If we divide 270 by 72, we get 3 and a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 216 from 270 to get 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 72

Going ahead to step 5:
When dividing 548 by 72, we get 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 637.0
The remainder is 44 after subtracting 504 from 548.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 72

Going ahead to step 6:
72 can be fit into 449 6 times, resulting in a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 6376.0
Subtract 432 from 449 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 72

Advancing to step 7:
The number 72 fits into 172 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 63762.0
The remainder is 28 after subtracting 144 from 172.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 72

Going ahead to step 8:
72 goes into 280 3 times with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 637623.0
Subtract 216 from 280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 637623.8
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
72 goes into 640 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 637623.88
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 637623.88 with a remaining 0.064.
