45072301 ÷ 319 
Let's see how many times 319 fits into 45072301.

Advancing to step 1:
The number 319 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 319

On to step 2:
If we divide 45 by 319, 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.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 319

Let's proceed to step 3:
If we divide 450 by 319, we get 1 and a remainder of 131.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 319 from 450 leaves us with 131.
Take the next digit (7) from the dividend and append it to 131, then repeat: 1317 / 319

Let's proceed to step 4:
319 can be fit into 1317 4 times, resulting in a remainder of 41.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1276 from 1317 and we're left with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 319

On to step 5:
412 divided by 319 is 1 with a remainder of 93.
The next digit of our result is 1. 
Result so far: 141.0
Subtract 319 from 412 to get 93.
Include the next digit (3) from the dividend after 93, then repeat: 933 / 319

Advancing to step 6:
The number 319 fits into 933 2 times, leaving a remainder of 295.
Write down 2 as next digit of the result. 
Result so far: 1412.0
Subtracting 638 from 933 leaves us with 295.
Include the next digit (0) from the dividend after 295, then repeat: 2950 / 319

On to step 7:
When dividing 2950 by 319, we get 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 14129.0
Subtracting 2871 from 2950 leaves us with 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 319

Let's proceed to step 8:
319 can be fit into 791 2 times, resulting in a remainder of 153.
Use 2 as the next digit of our solution. 
Result so far: 141292.0
If we take 638 away from 791, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 9:
319 can be fit into 1530 4 times, resulting in a remainder of 254.
The next digit of our result is 4. 
Result so far: 141292.4
Subtracting 1276 from 1530 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 10:
319 can be fit into 2540 7 times, resulting in a remainder of 307.
Put 7 as the next digit of the answer. 
Result so far: 141292.47
If we subtract 2233 from 2540, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 11:
319 can be fit into 3070 9 times, resulting in a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 141292.479
Deduct 2871 from 3070 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 12:
The number 319 fits into 1990 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 141292.4796
Deduct 1914 from 1990 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
The number 319 fits into 760 2 times, leaving a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 141292.47962
If we subtract 638 from 760, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 14:
When dividing 1220 by 319, we get 3 with a remainder of 263.
Record the quotient 3 as the next digit in the result. 
Result so far: 141292.479623
If we subtract 957 from 1220, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 15:
319 goes into 2630 8 times with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 141292.4796238
If we subtract 2552 from 2630, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 16:
If we divide 780 by 319, we get 2 and a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 141292.47962382
Subtract 638 from 780 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

In conclusion, the division gives 141292.47962382 with a balance of 1.42e-07.
