We divide 40152012 by 102
Our goal is to divide 40152012 by 102.

Going ahead to step 1:
4 divided by 102 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 102

On to step 2:
40 divided by 102 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 102

Advancing to step 3:
102 goes into 401 3 times with a remainder of 95.
The next digit of our result is 3. 
Result so far: 3.0
If we take 306 away from 401, we end up with 95.
Take the next digit (5) from the dividend and append it to 95, then repeat: 955 / 102

Let's proceed to step 4:
The number 102 fits into 955 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 918 from 955, we get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 102

Going ahead to step 5:
102 can be fit into 372 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
If we take 306 away from 372, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 102

Moving on to step 6:
When dividing 660 by 102, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 3936.0
If we take 612 away from 660, we end up with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 102

Step 7:
When dividing 481 by 102, we get 4 with a remainder of 73.
Use 4 as the next digit of our solution. 
Result so far: 39364.0
Subtract 408 from 481 to get 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 102

Step 8:
732 divided by 102 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 393647.0
Subtract 714 from 732 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 102, we get 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 393647.1
Subtracting 102 from 180 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
102 goes into 780 7 times with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 393647.17
The remainder is 66 after subtracting 714 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
When dividing 660 by 102, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 393647.176
If we subtract 612 from 660, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
When dividing 480 by 102, we get 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 393647.1764
If we take 408 away from 480, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
720 divided by 102 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 393647.17647
Deduct 714 from 720 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.

Let's proceed to step 14:
If we divide 60 by 102, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 393647.17647
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
102 can be fit into 600 5 times, resulting in a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 393647.1764705
Subtract 510 from 600 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 16:
When dividing 900 by 102, we get 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 393647.17647058
Subtract 816 from 900 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

In conclusion, the division gives 393647.17647058 with a balance of 8.4e-08.
