15480436 divided by 390 
We want to figure out the number of times 15480436 can be divided by 390.

On to step 1:
390 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 390

On to step 2:
If we divide 15 by 390, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 390

Let's proceed to step 3:
When dividing 154 by 390, we get 0 with a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Bring next digit (8) of the dividend behind the 154 and repeat the process: 1548 / 390

Going ahead to step 4:
1548 divided by 390 is 3 with a remainder of 378.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1170 away from 1548, we end up with 378.
Take the next digit (0) from the dividend and append it to 378, then repeat: 3780 / 390

Moving on to step 5:
3780 divided by 390 is 9 with a remainder of 270.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 3510 from 3780 leaves us with 270.
Fetch the next digit (4) from the dividend, attach it to 270 and continue: 2704 / 390

Moving on to step 6:
The number 390 fits into 2704 6 times, leaving a remainder of 364.
Use 6 as the next digit of our solution. 
Result so far: 396.0
The remainder is 364 after subtracting 2340 from 2704.
Take the next digit (3) from the dividend and append it to 364, then repeat: 3643 / 390

Advancing to step 7:
3643 divided by 390 is 9 with a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 3969.0
If we take 3510 away from 3643, we end up with 133.
Grab the next digit (6) from the dividend, add it to 133, then carry on: 1336 / 390

Advancing to step 8:
390 goes into 1336 3 times with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 39693.0
If we take 1170 away from 1336, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 9:
1660 divided by 390 is 4 with a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 39693.4
Deduct 1560 from 1660 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
When dividing 1000 by 390, we get 2 with a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 39693.42
If we subtract 780 from 1000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
2200 divided by 390 is 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 39693.425
If we take 1950 away from 2200, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
The number 390 fits into 2500 6 times, leaving a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 39693.4256
Deduct 2340 from 2500 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
The number 390 fits into 1600 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 39693.42564
If we take 1560 away from 1600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
When dividing 400 by 390, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 39693.425641
If we take 390 away from 400, we end up 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.

Let's proceed to step 15:
390 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 39693.425641
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
390 goes into 1000 2 times with a remainder of 220.
Record the quotient 2 as the next digit in the result. 
Result so far: 39693.42564102
The remainder is 220 after subtracting 780 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 39693.42564102 with a remainder of 2.2e-07.
