45143097 ÷ 319 
Our goal is to divide 45143097 by 319.

Moving on to step 1:
If we divide 4 by 319, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 319

Step 2:
The number 319 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 319

Moving on to step 3:
319 can be fit into 451 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 132 after subtracting 319 from 451.
Grab the next digit (4) from the dividend, add it to 132, then carry on: 1324 / 319

Advancing to step 4:
319 can be fit into 1324 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 48 after subtracting 1276 from 1324.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 319

Advancing to step 5:
483 divided by 319 is 1 with a remainder of 164.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we take 319 away from 483, we end up with 164.
Grab the next digit (0) from the dividend, add it to 164, then carry on: 1640 / 319

Step 6:
1640 divided by 319 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1415.0
Subtracting 1595 from 1640 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 319

On to step 7:
The number 319 fits into 459 1 times, leaving a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 14151.0
Deduct 319 from 459 and we're left with 140.
Include the next digit (7) from the dividend after 140, then repeat: 1407 / 319

On to step 8:
When dividing 1407 by 319, we get 4 with a remainder of 131.
Use 4 as the next digit of our solution. 
Result so far: 141514.0
Subtracting 1276 from 1407 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
319 can be fit into 1310 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 141514.4
If we take 1276 away from 1310, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
The number 319 fits into 340 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 141514.41
If we subtract 319 from 340, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
The number 319 fits into 210 0 times, leaving a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 141514.41
The remainder is 210 after subtracting 0 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 12:
319 goes into 2100 6 times with a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 141514.4106
Subtract 1914 from 2100 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 13:
If we divide 1860 by 319, we get 5 and a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 141514.41065
The remainder is 265 after subtracting 1595 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 14:
If we divide 2650 by 319, we get 8 and a remainder of 98.
The next digit of our result is 8. 
Result so far: 141514.410658
Subtract 2552 from 2650 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 15:
If we divide 980 by 319, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 141514.4106583
If we take 957 away from 980, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 16:
If we divide 230 by 319, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 141514.4106583
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

In conclusion, the division gives 141514.4106583 with a balance of 2.3e-07.
