We divide 394503 by 51
We want to divide 394503 by 51.

On to step 1:
51 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 51

Moving on to step 2:
If we divide 39 by 51, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 51

Moving on to step 3:
The number 51 fits into 394 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 37 after subtracting 357 from 394.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 51

On to step 4:
51 goes into 375 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 77.0
The remainder is 18 after subtracting 357 from 375.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 51

On to step 5:
When dividing 180 by 51, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 773.0
If we take 153 away from 180, we end up with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 51

Let's proceed to step 6:
The number 51 fits into 273 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 7735.0
Subtract 255 from 273 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 7735.3
If we take 153 away from 180, we end up with 27.
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 8:
If we divide 270 by 51, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 7735.35
Subtract 255 from 270 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
When dividing 150 by 51, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 7735.352
Deduct 102 from 150 and we're left 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.

Let's proceed to step 10:
51 goes into 480 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7735.3529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 7735.35294
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
51 can be fit into 60 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 7735.352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 7735.3529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 7735.3529411, and the remainder is 3.9e-07.
