We're dividing 9990013 by 390 
We want to divide 9990013 by 390.

Moving on to step 1:
If we divide 9 by 390, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 390

On to step 2:
390 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Take the next digit (9) from the dividend and append it to 99, then repeat: 999 / 390

Going ahead to step 3:
999 divided by 390 is 2 with a remainder of 219.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 780 away from 999, we end up with 219.
Fetch the next digit (0) from the dividend, attach it to 219 and continue: 2190 / 390

On to step 4:
390 goes into 2190 5 times with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 1950 from 2190 to get 240.
Append the next digit (0) from the dividend to 240 and continue with: 2400 / 390

Moving on to step 5:
The number 390 fits into 2400 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 256.0
Deduct 2340 from 2400 and we're left with 60.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 390

On to step 6:
When dividing 601 by 390, we get 1 with a remainder of 211.
Write down 1 as next digit of the result. 
Result so far: 2561.0
Subtracting 390 from 601 leaves us with 211.
Grab the next digit (3) from the dividend, add it to 211, then carry on: 2113 / 390

On to step 7:
The number 390 fits into 2113 5 times, leaving a remainder of 163.
Write down 5 as next digit of the result. 
Result so far: 25615.0
If we take 1950 away from 2113, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 8:
If we divide 1630 by 390, we get 4 and a remainder of 70.
The next digit of our result is 4. 
Result so far: 25615.4
If we subtract 1560 from 1630, 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.

Going ahead to step 9:
If we divide 700 by 390, we get 1 and a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 25615.41
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.

Moving on to step 10:
The number 390 fits into 3100 7 times, leaving a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 25615.417
If we subtract 2730 from 3100, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 11:
When dividing 3700 by 390, we get 9 with a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 25615.4179
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.

On to step 12:
If we divide 1900 by 390, we get 4 and a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 25615.41794
If we subtract 1560 from 1900, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
If we divide 3400 by 390, we get 8 and a remainder of 280.
The next digit of our result is 8. 
Result so far: 25615.417948
Subtracting 3120 from 3400 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
The number 390 fits into 2800 7 times, leaving a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 25615.4179487
The remainder is 70 after subtracting 2730 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
700 divided by 390 is 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 25615.41794871
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.

The final result is 25615.41794871 with a remainder of 3.1e-07.
