Let's divide 20439022 by 393
We want to divide 20439022 by 393.

Let's proceed to step 1:
393 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 393

Let's proceed to step 2:
If we divide 20 by 393, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 393

Advancing to step 3:
If we divide 204 by 393, we get 0 and a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 204 to get 204.
Include the next digit (3) from the dividend after 204, then repeat: 2043 / 393

Advancing to step 4:
393 can be fit into 2043 5 times, resulting in a remainder of 78.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 1965 from 2043, we get 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 393

On to step 5:
The number 393 fits into 789 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 786 away from 789, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 393

Advancing to step 6:
30 divided by 393 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 520.0
If we subtract 0 from 30, we get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 393

On to step 7:
393 goes into 302 0 times with a remainder of 302.
Write down 0 as next digit of the result. 
Result so far: 5200.0
Subtracting 0 from 302 leaves us with 302.
Include the next digit (2) from the dividend after 302, then repeat: 3022 / 393

On to step 8:
393 goes into 3022 7 times with a remainder of 271.
The number 7 becomes the next digit in our result. 
Result so far: 52007.0
Deduct 2751 from 3022 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 9:
The number 393 fits into 2710 6 times, leaving a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 52007.6
If we take 2358 away from 2710, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 10:
When dividing 3520 by 393, we get 8 with a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 52007.68
Subtracting 3144 from 3520 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
393 goes into 3760 9 times with a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 52007.689
Subtract 3537 from 3760 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 12:
393 can be fit into 2230 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 52007.6895
Subtracting 1965 from 2230 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 13:
The number 393 fits into 2650 6 times, leaving a remainder of 292.
Put 6 as the next digit of the answer. 
Result so far: 52007.68956
Subtracting 2358 from 2650 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 14:
393 can be fit into 2920 7 times, resulting in a remainder of 169.
Put 7 as the next digit of the answer. 
Result so far: 52007.689567
If we subtract 2751 from 2920, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 15:
The number 393 fits into 1690 4 times, leaving a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 52007.6895674
The remainder is 118 after subtracting 1572 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 16:
393 can be fit into 1180 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 52007.68956743
Deduct 1179 from 1180 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 52007.68956743, with a leftover of 1e-09.
