45101303 ÷ 14 
Our goal is to divide 45101303 by 14.

On to step 1:
14 goes into 4 0 times with 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.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 14

Moving on to step 2:
45 divided by 14 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 42 from 45 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 14

Let's proceed to step 3:
31 divided by 14 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 28 from 31, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 14

Moving on to step 4:
14 goes into 30 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 322.0
Deduct 28 from 30 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 14

On to step 5:
14 can be fit into 21 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3221.0
Subtract 14 from 21 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 14

Moving on to step 6:
If we divide 73 by 14, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 32215.0
Deduct 70 from 73 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 14

Let's proceed to step 7:
If we divide 30 by 14, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 322152.0
The remainder is 2 after subtracting 28 from 30.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 14

Going ahead to step 8:
14 can be fit into 23 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 3221521.0
The remainder is 9 after subtracting 14 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 14 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 3221521.6
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
60 divided by 14 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 3221521.64
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3221521.642
Subtracting 28 from 40 leaves us with 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 12:
When dividing 120 by 14, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 3221521.6428
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
14 goes into 80 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3221521.64285
Subtracting 70 from 80 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 3221521.642857
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 3221521.6428571
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 16:
60 divided by 14 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3221521.64285714
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 3221521.64285714 with a remaining 4e-09.
