38973513 divided by 390 
We want to divide 38973513 by 390.

Going ahead to step 1:
If we divide 3 by 390, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 390

Moving on to step 2:
38 divided by 390 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 390

On to step 3:
When dividing 389 by 390, we get 0 with a remainder of 389.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 389, we end up with 389.
Append the next digit (7) from the dividend to 389 and continue with: 3897 / 390

Advancing to step 4:
390 can be fit into 3897 9 times, resulting in a remainder of 387.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 3510 away from 3897, we end up with 387.
Append the next digit (3) from the dividend to 387 and continue with: 3873 / 390

Step 5:
390 can be fit into 3873 9 times, resulting in a remainder of 363.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtract 3510 from 3873 to get 363.
Bring next digit (5) of the dividend behind the 363 and repeat the process: 3635 / 390

Let's proceed to step 6:
390 can be fit into 3635 9 times, resulting in a remainder of 125.
Put 9 as the next digit of the answer. 
Result so far: 999.0
If we take 3510 away from 3635, we end up with 125.
Include the next digit (1) from the dividend after 125, then repeat: 1251 / 390

Moving on to step 7:
If we divide 1251 by 390, we get 3 and a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 9993.0
If we take 1170 away from 1251, we end up with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 390

Moving on to step 8:
The number 390 fits into 813 2 times, leaving a remainder of 33.
The next digit of our result is 2. 
Result so far: 99932.0
Subtracting 780 from 813 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
330 divided by 390 is 0 with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 99932.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
390 goes into 3300 8 times with a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 99932.08
Deduct 3120 from 3300 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
If we divide 1800 by 390, we get 4 and a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 99932.084
If we subtract 1560 from 1800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
If we divide 2400 by 390, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 99932.0846
Subtracting 2340 from 2400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
The number 390 fits into 600 1 times, leaving a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 99932.08461
Subtract 390 from 600 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 14:
390 goes into 2100 5 times with a remainder of 150.
The next digit of our result is 5. 
Result so far: 99932.084615
Deduct 1950 from 2100 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
When dividing 1500 by 390, we get 3 with a remainder of 330.
The number 3 becomes the next digit in our result. 
Result so far: 99932.0846153
The remainder is 330 after subtracting 1170 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 16:
If we divide 3300 by 390, we get 8 and a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 99932.08461538
The remainder is 180 after subtracting 3120 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 99932.08461538, with a leftover of 1.8e-07.
