We look at the division of 51303837 by 390 
Our goal is to divide 51303837 by 390.

Advancing to step 1:
390 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 390

On to step 2:
When dividing 51 by 390, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 390

Going ahead to step 3:
390 can be fit into 513 1 times, resulting in a remainder of 123.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 390 from 513, we get 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 390

Step 4:
When dividing 1230 by 390, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1170 from 1230 leaves us with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 390

Advancing to step 5:
If we divide 603 by 390, we get 1 and a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 131.0
Subtract 390 from 603 to get 213.
Include the next digit (8) from the dividend after 213, then repeat: 2138 / 390

Going ahead to step 6:
2138 divided by 390 is 5 with a remainder of 188.
The number 5 becomes the next digit in our result. 
Result so far: 1315.0
Subtracting 1950 from 2138 leaves us with 188.
Include the next digit (3) from the dividend after 188, then repeat: 1883 / 390

Advancing to step 7:
When dividing 1883 by 390, we get 4 with a remainder of 323.
Put 4 as the next digit of the answer. 
Result so far: 13154.0
Subtract 1560 from 1883 to get 323.
Take the next digit (7) from the dividend and append it to 323, then repeat: 3237 / 390

Let's proceed to step 8:
390 can be fit into 3237 8 times, resulting in a remainder of 117.
The number 8 becomes the next digit in our result. 
Result so far: 131548.0
The remainder is 117 after subtracting 3120 from 3237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
If we divide 1170 by 390, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 131548.3
Subtract 1170 from 1170 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
390 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 131548.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 390, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 131548.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 131548.3, with a leftover of 0.0.
