55 divided by 393 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 393

Let's proceed to step 3:
When dividing 554 by 393, we get 1 with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 393 away from 554, we end up with 161.
Include the next digit (4) from the dividend after 161, then repeat: 1614 / 393

Advancing to step 4:
The number 393 fits into 1614 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1572 from 1614 to get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 393

Let's proceed to step 5:
If we divide 428 by 393, we get 1 and a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 141.0
The remainder is 35 after subtracting 393 from 428.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 393

Step 6:
The number 393 fits into 356 0 times, leaving a remainder of 356.
Record the quotient 0 as the next digit in the result. 
Result so far: 1410.0
Subtract 0 from 356 to get 356.
Grab the next digit (2) from the dividend, add it to 356, then carry on: 3562 / 393

Moving on to step 7:
3562 divided by 393 is 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 14109.0
The remainder is 25 after subtracting 3537 from 3562.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 393

Going ahead to step 8:
250 divided by 393 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 141090.0
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
393 goes into 2500 6 times with a remainder of 142.
Record the quotient 6 as the next digit in the result. 
Result so far: 141090.6
Subtracting 2358 from 2500 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
If we divide 1420 by 393, we get 3 and a remainder of 241.
Put 3 as the next digit of the answer. 
Result so far: 141090.63
Subtract 1179 from 1420 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 11:
393 can be fit into 2410 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 141090.636
Deduct 2358 from 2410 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
When dividing 520 by 393, we get 1 with a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 141090.6361
The remainder is 127 after subtracting 393 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 13:
393 can be fit into 1270 3 times, resulting in a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 141090.63613
Subtract 1179 from 1270 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 14:
When dividing 910 by 393, we get 2 with a remainder of 124.
The next digit of our result is 2. 
Result so far: 141090.636132
Subtract 786 from 910 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 15:
393 can be fit into 1240 3 times, resulting in a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 141090.6361323
If we take 1179 away from 1240, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 16:
If we divide 610 by 393, we get 1 and a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 141090.63613231
Subtracting 393 from 610 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Our division results in 141090.63613231 with a remaining 2.17e-07.
