1512487 divided by 408 
We want to divide 1512487 by 408.

Moving on to step 1:
1 divided by 408 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 408

On to step 2:
The number 408 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 408

Going ahead to step 3:
When dividing 151 by 408, we get 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 151 and we're left with 151.
Grab the next digit (2) from the dividend, add it to 151, then carry on: 1512 / 408

Moving on to step 4:
If we divide 1512 by 408, we get 3 and a remainder of 288.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1224 from 1512, we get 288.
Include the next digit (4) from the dividend after 288, then repeat: 2884 / 408

Advancing to step 5:
408 goes into 2884 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 2856 from 2884, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 408

Let's proceed to step 6:
If we divide 288 by 408, we get 0 and a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 370.0
Subtract 0 from 288 to get 288.
Append the next digit (7) from the dividend to 288 and continue with: 2887 / 408

Going ahead to step 7:
408 goes into 2887 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 3707.0
Subtracting 2856 from 2887 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
310 divided by 408 is 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 3707.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
408 goes into 3100 7 times with a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 3707.07
Subtract 2856 from 3100 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
When dividing 2440 by 408, we get 5 with a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 3707.075
If we take 2040 away from 2440, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
The number 408 fits into 4000 9 times, leaving a remainder of 328.
Record the quotient 9 as the next digit in the result. 
Result so far: 3707.0759
Subtract 3672 from 4000 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 12:
408 goes into 3280 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3707.07598
Subtract 3264 from 3280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 408, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 3707.07598
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 408, we get 3 with a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 3707.0759803
If we subtract 1224 from 1600, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 15:
408 can be fit into 3760 9 times, resulting in a remainder of 88.
The next digit of our result is 9. 
Result so far: 3707.07598039
Deduct 3672 from 3760 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 3707.07598039 with a balance of 8.8e-08.
