We look at the division of 38310409 by 390 
Our goal is to divide 38310409 by 390.

Step 1:
The number 390 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 390

Let's proceed to step 2:
The number 390 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 390

Going ahead to step 3:
383 divided by 390 is 0 with a remainder of 383.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 383, we get 383.
Take the next digit (1) from the dividend and append it to 383, then repeat: 3831 / 390

Going ahead to step 4:
3831 divided by 390 is 9 with a remainder of 321.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 3510 away from 3831, we end up with 321.
Take the next digit (0) from the dividend and append it to 321, then repeat: 3210 / 390

Going ahead to step 5:
390 goes into 3210 8 times with a remainder of 90.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 3120 from 3210 leaves us with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 390

On to step 6:
If we divide 904 by 390, we get 2 and a remainder of 124.
The next digit of our result is 2. 
Result so far: 982.0
Subtracting 780 from 904 leaves us with 124.
Grab the next digit (0) from the dividend, add it to 124, then carry on: 1240 / 390

On to step 7:
390 can be fit into 1240 3 times, resulting in a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 9823.0
If we take 1170 away from 1240, we end up with 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 390

Step 8:
390 goes into 709 1 times with a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 98231.0
Subtracting 390 from 709 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 9:
390 can be fit into 3190 8 times, resulting in a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 98231.8
If we subtract 3120 from 3190, we 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.

Moving on to step 10:
390 goes into 700 1 times with a remainder of 310.
The next digit of our result is 1. 
Result so far: 98231.81
If we take 390 away from 700, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
390 can be fit into 3100 7 times, resulting in a remainder of 370.
The next digit of our result is 7. 
Result so far: 98231.817
Subtracting 2730 from 3100 leaves us 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.

Step 12:
3700 divided by 390 is 9 with a remainder of 190.
Record the quotient 9 as the next digit in the result. 
Result so far: 98231.8179
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.

Advancing to step 13:
390 can be fit into 1900 4 times, resulting in a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 98231.81794
If we take 1560 away from 1900, we end up 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.

Moving on to step 14:
390 can be fit into 3400 8 times, resulting in a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 98231.817948
Subtract 3120 from 3400 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
390 goes into 2800 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 98231.8179487
Subtract 2730 from 2800 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.

Moving on to step 16:
390 can be fit into 700 1 times, resulting in a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 98231.81794871
Deduct 390 from 700 and we're left with 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 98231.81794871 with a balance of 3.1e-07.
