We're dividing 393345 by 57 
Let's see how many times 57 fits into 393345.

On to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 57

Step 2:
The number 57 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 57

Moving on to step 3:
57 can be fit into 393 6 times, resulting in a remainder of 51.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 342 from 393 to get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 57

On to step 4:
513 divided by 57 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 513 from 513 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 57

Moving on to step 5:
If we divide 4 by 57, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 690.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 57

Moving on to step 6:
45 divided by 57 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 6900.0
Subtracting 0 from 45 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
The number 57 fits into 450 7 times, leaving a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 6900.7
If we take 399 away from 450, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 8:
If we divide 510 by 57, we get 8 and a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 6900.78
The remainder is 54 after subtracting 456 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
The number 57 fits into 540 9 times, leaving a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 6900.789
The remainder is 27 after subtracting 513 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
If we divide 270 by 57, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 6900.7894
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
When dividing 420 by 57, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 6900.78947
If we subtract 399 from 420, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
57 can be fit into 210 3 times, resulting in a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 6900.789473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
390 divided by 57 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6900.7894736
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
57 goes into 480 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 6900.78947368
If we take 456 away from 480, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 6900.78947368 with a remainder of 2.4e-08.
