Let's divide 19642959 by 393
Our goal is to divide 19642959 by 393.

Let's proceed to step 1:
If we divide 1 by 393, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 393

Advancing to step 2:
When dividing 19 by 393, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 393

Let's proceed to step 3:
196 divided by 393 is 0 with a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 196 after subtracting 0 from 196.
Grab the next digit (4) from the dividend, add it to 196, then carry on: 1964 / 393

Step 4:
393 can be fit into 1964 4 times, resulting in a remainder of 392.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1572 away from 1964, we end up with 392.
Grab the next digit (2) from the dividend, add it to 392, then carry on: 3922 / 393

On to step 5:
393 can be fit into 3922 9 times, resulting in a remainder of 385.
Write down 9 as next digit of the result. 
Result so far: 49.0
The remainder is 385 after subtracting 3537 from 3922.
Grab the next digit (9) from the dividend, add it to 385, then carry on: 3859 / 393

Let's proceed to step 6:
393 goes into 3859 9 times with a remainder of 322.
Use 9 as the next digit of our solution. 
Result so far: 499.0
Subtract 3537 from 3859 to get 322.
Append the next digit (5) from the dividend to 322 and continue with: 3225 / 393

Going ahead to step 7:
3225 divided by 393 is 8 with a remainder of 81.
Write down 8 as next digit of the result. 
Result so far: 4998.0
Deduct 3144 from 3225 and we're left with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 393

Advancing to step 8:
When dividing 819 by 393, we get 2 with a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 49982.0
The remainder is 33 after subtracting 786 from 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
330 divided by 393 is 0 with a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 49982.0
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:
3300 divided by 393 is 8 with a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 49982.08
Deduct 3144 from 3300 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 11:
If we divide 1560 by 393, we get 3 and a remainder of 381.
Record the quotient 3 as the next digit in the result. 
Result so far: 49982.083
If we take 1179 away from 1560, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 12:
393 goes into 3810 9 times with a remainder of 273.
Record the quotient 9 as the next digit in the result. 
Result so far: 49982.0839
Subtracting 3537 from 3810 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 13:
When dividing 2730 by 393, we get 6 with a remainder of 372.
The number 6 becomes the next digit in our result. 
Result so far: 49982.08396
If we take 2358 away from 2730, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 14:
3720 divided by 393 is 9 with a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 49982.083969
The remainder is 183 after subtracting 3537 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 15:
393 can be fit into 1830 4 times, resulting in a remainder of 258.
The number 4 becomes the next digit in our result. 
Result so far: 49982.0839694
The remainder is 258 after subtracting 1572 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 16:
2580 divided by 393 is 6 with a remainder of 222.
The next digit of our result is 6. 
Result so far: 49982.08396946
If we subtract 2358 from 2580, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final outcome is 49982.08396946, with a leftover of 2.22e-07.
