We divide 57457830 by 399
Let's see how many times 399 fits into 57457830.

Step 1:
If we divide 5 by 399, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 399

Moving on to step 2:
399 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.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 399

On to step 3:
If we divide 574 by 399, we get 1 and a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 399 away from 574, we end up with 175.
Grab the next digit (5) from the dividend, add it to 175, then carry on: 1755 / 399

On to step 4:
When dividing 1755 by 399, we get 4 with a remainder of 159.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1596 from 1755 to get 159.
Bring next digit (7) of the dividend behind the 159 and repeat the process: 1597 / 399

Let's proceed to step 5:
The number 399 fits into 1597 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtracting 1596 from 1597 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 399

Step 6:
When dividing 18 by 399, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 1440.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 399

Advancing to step 7:
If we divide 183 by 399, we get 0 and a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 14400.0
If we take 0 away from 183, we end up with 183.
Include the next digit (0) from the dividend after 183, then repeat: 1830 / 399

On to step 8:
1830 divided by 399 is 4 with a remainder of 234.
Use 4 as the next digit of our solution. 
Result so far: 144004.0
Subtracting 1596 from 1830 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
399 goes into 2340 5 times with a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 144004.5
If we take 1995 away from 2340, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 10:
3450 divided by 399 is 8 with a remainder of 258.
Put 8 as the next digit of the answer. 
Result so far: 144004.58
If we subtract 3192 from 3450, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 11:
399 can be fit into 2580 6 times, resulting in a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 144004.586
The remainder is 186 after subtracting 2394 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 12:
If we divide 1860 by 399, we get 4 and a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 144004.5864
Subtracting 1596 from 1860 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 13:
399 goes into 2640 6 times with a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 144004.58646
Subtract 2394 from 2640 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 14:
When dividing 2460 by 399, we get 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 144004.586466
If we take 2394 away from 2460, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 144004.586466, and the remainder is 6.6e-06.
