We divide 57144262 by 393
Our goal is to divide 57144262 by 393.

On to step 1:
When dividing 5 by 393, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 393

Moving on to step 2:
393 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 393

Moving on to step 3:
393 can be fit into 571 1 times, resulting in a remainder of 178.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 178 after subtracting 393 from 571.
Fetch the next digit (4) from the dividend, attach it to 178 and continue: 1784 / 393

Advancing to step 4:
1784 divided by 393 is 4 with a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1572 from 1784 to get 212.
Take the next digit (4) from the dividend and append it to 212, then repeat: 2124 / 393

Step 5:
393 can be fit into 2124 5 times, resulting in a remainder of 159.
Put 5 as the next digit of the answer. 
Result so far: 145.0
If we take 1965 away from 2124, we end up with 159.
Include the next digit (2) from the dividend after 159, then repeat: 1592 / 393

Moving on to step 6:
When dividing 1592 by 393, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1454.0
If we take 1572 away from 1592, we end up with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 393

Let's proceed to step 7:
If we divide 206 by 393, we get 0 and a remainder of 206.
Put 0 as the next digit of the answer. 
Result so far: 14540.0
If we take 0 away from 206, we end up with 206.
Bring next digit (2) of the dividend behind the 206 and repeat the process: 2062 / 393

Going ahead to step 8:
If we divide 2062 by 393, we get 5 and a remainder of 97.
The next digit of our result is 5. 
Result so far: 145405.0
Deduct 1965 from 2062 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
970 divided by 393 is 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 145405.2
If we subtract 786 from 970, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
The number 393 fits into 1840 4 times, leaving a remainder of 268.
Write down 4 as next digit of the result. 
Result so far: 145405.24
Subtract 1572 from 1840 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 11:
393 can be fit into 2680 6 times, resulting in a remainder of 322.
Write down 6 as next digit of the result. 
Result so far: 145405.246
Deduct 2358 from 2680 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 12:
3220 divided by 393 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 145405.2468
If we take 3144 away from 3220, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
If we divide 760 by 393, we get 1 and a remainder of 367.
The number 1 becomes the next digit in our result. 
Result so far: 145405.24681
If we subtract 393 from 760, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 14:
If we divide 3670 by 393, we get 9 and a remainder of 133.
The next digit of our result is 9. 
Result so far: 145405.246819
Subtract 3537 from 3670 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 15:
When dividing 1330 by 393, we get 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 145405.2468193
Deduct 1179 from 1330 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 16:
The number 393 fits into 1510 3 times, leaving a remainder of 331.
Record the quotient 3 as the next digit in the result. 
Result so far: 145405.24681933
Subtracting 1179 from 1510 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final outcome is 145405.24681933, with a leftover of 3.31e-07.
