We divide 13851510 by 390
We want to figure out the number of times 13851510 can be divided by 390.

Advancing to step 1:
If we divide 1 by 390, we get 0 and 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.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 390

Let's proceed to step 2:
If we divide 13 by 390, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 390

Step 3:
138 divided by 390 is 0 with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 390

Advancing to step 4:
The number 390 fits into 1385 3 times, leaving a remainder of 215.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1170 from 1385 to get 215.
Grab the next digit (1) from the dividend, add it to 215, then carry on: 2151 / 390

Moving on to step 5:
If we divide 2151 by 390, we get 5 and a remainder of 201.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 1950 from 2151, we get 201.
Take the next digit (5) from the dividend and append it to 201, then repeat: 2015 / 390

Step 6:
390 can be fit into 2015 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 355.0
Subtract 1950 from 2015 to get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 390

On to step 7:
If we divide 651 by 390, we get 1 and a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 3551.0
If we subtract 390 from 651, we get 261.
Grab the next digit (0) from the dividend, add it to 261, then carry on: 2610 / 390

Let's proceed to step 8:
When dividing 2610 by 390, we get 6 with a remainder of 270.
The next digit of our result is 6. 
Result so far: 35516.0
Subtract 2340 from 2610 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 9:
390 can be fit into 2700 6 times, resulting in a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 35516.6
The remainder is 360 after subtracting 2340 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 10:
The number 390 fits into 3600 9 times, leaving a remainder of 90.
Record the quotient 9 as the next digit in the result. 
Result so far: 35516.69
If we take 3510 away from 3600, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
If we divide 900 by 390, we get 2 and a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 35516.692
Subtract 780 from 900 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
The number 390 fits into 1200 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 35516.6923
Subtracting 1170 from 1200 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.

Moving on to step 13:
390 can be fit into 300 0 times, resulting in a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 35516.6923
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 14:
If we divide 3000 by 390, we get 7 and a remainder of 270.
Write down 7 as next digit of the result. 
Result so far: 35516.692307
The remainder is 270 after subtracting 2730 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 15:
390 can be fit into 2700 6 times, resulting in a remainder of 360.
Write down 6 as next digit of the result. 
Result so far: 35516.6923076
Subtracting 2340 from 2700 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 16:
3600 divided by 390 is 9 with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 35516.69230769
Deduct 3510 from 3600 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 35516.69230769 with a remaining 9e-08.
