72919574 divided by 45 
Our goal is to divide 72919574 by 45.

On to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 45

Step 2:
72 divided by 45 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 72 to get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 45

Advancing to step 3:
45 can be fit into 279 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 270 away from 279, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 45

Step 4:
45 goes into 91 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Subtract 90 from 91 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 45

On to step 5:
19 divided by 45 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 1620.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 45

Advancing to step 6:
45 goes into 195 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 16204.0
The remainder is 15 after subtracting 180 from 195.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 45

Advancing to step 7:
157 divided by 45 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 162043.0
Subtract 135 from 157 to get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 45

Let's proceed to step 8:
224 divided by 45 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 1620434.0
If we take 180 away from 224, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
The number 45 fits into 440 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 1620434.9
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
45 goes into 350 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 1620434.97
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
If we divide 350 by 45, we get 7 and a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 1620434.977
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 1620434.977 with a balance of 0.0035.
