16487452 divided by 390 
We're looking to find how many times 390 goes into 16487452.

On to step 1:
When dividing 1 by 390, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 390

Going ahead to step 2:
When dividing 16 by 390, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 390

Step 3:
The number 390 fits into 164 0 times, leaving a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0

Fetch the next digit (8) from the dividend, attach it to 164 and continue: 1648 / 390

Going ahead to step 4:
390 goes into 1648 4 times with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1560 from 1648 and we're left with 88.
Fetch the next digit (7) from the dividend, attach it to 88 and continue: 887 / 390

Step 5:
If we divide 887 by 390, we get 2 and a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 107 after subtracting 780 from 887.
Take the next digit (4) from the dividend and append it to 107, then repeat: 1074 / 390

Let's proceed to step 6:
390 can be fit into 1074 2 times, resulting in a remainder of 294.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
Subtract 780 from 1074 to get 294.
Append the next digit (5) from the dividend to 294 and continue with: 2945 / 390

Step 7:
2945 divided by 390 is 7 with a remainder of 215.
The next digit of our result is 7. 
Result so far: 4227.0
Subtracting 2730 from 2945 leaves us with 215.
Bring next digit (2) of the dividend behind the 215 and repeat the process: 2152 / 390

On to step 8:
If we divide 2152 by 390, we get 5 and a remainder of 202.
Put 5 as the next digit of the answer. 
Result so far: 42275.0
If we subtract 1950 from 2152, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 9:
The number 390 fits into 2020 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 42275.5
Subtract 1950 from 2020 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
When dividing 700 by 390, we get 1 with a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 42275.51
If we subtract 390 from 700, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
When dividing 3100 by 390, we get 7 with a remainder of 370.
Put 7 as the next digit of the answer. 
Result so far: 42275.517
Deduct 2730 from 3100 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 12:
When dividing 3700 by 390, we get 9 with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 42275.5179
If we subtract 3510 from 3700, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 13:
390 can be fit into 1900 4 times, resulting in a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 42275.51794
Deduct 1560 from 1900 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
390 goes into 3400 8 times with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 42275.517948
Deduct 3120 from 3400 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
The number 390 fits into 2800 7 times, leaving a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 42275.5179487
The remainder is 70 after subtracting 2730 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 16:
390 goes into 700 1 times with a remainder of 310.
The next digit of our result is 1. 
Result so far: 42275.51794871
Subtract 390 from 700 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 42275.51794871 with a balance of 3.1e-07.
