45012042 ÷ 39 
Let's see how many times 39 fits into 45012042.

Let's proceed to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 39

Going ahead to step 2:
39 can be fit into 45 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 39 from 45.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 39

Let's proceed to step 3:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 39 from 60 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 39

On to step 4:
The number 39 fits into 211 5 times, leaving a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 195 from 211 leaves us with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 39

Going ahead to step 5:
If we divide 162 by 39, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1154.0
Subtract 156 from 162 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 39

Let's proceed to step 6:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 11541.0
Subtracting 39 from 60 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 39

Step 7:
214 divided by 39 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 115415.0
Subtracting 195 from 214 leaves us with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 39

Let's proceed to step 8:
If we divide 192 by 39, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1154154.0
If we take 156 away from 192, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
39 goes into 360 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 1154154.9
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
90 divided by 39 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 1154154.92
If we take 78 away from 90, we end up 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.

Let's proceed to step 11:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1154154.923
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
If we divide 30 by 39, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1154154.923
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 1154154.92307
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1154154.923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 15:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1154154.9230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 16:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 1154154.92307692
If we take 78 away from 90, we end up 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.

Our division results in 1154154.92307692 with a remaining 1.2e-08.
