We're dividing 195393 by 51 
Let's see how many times 51 fits into 195393.

Going ahead to step 1:
If we divide 1 by 51, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 51

Moving on to step 2:
If we divide 19 by 51, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 51

Step 3:
51 can be fit into 195 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 153 away from 195, we end up with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 51

Step 4:
The number 51 fits into 423 8 times, leaving a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 408 from 423 to get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 51

On to step 5:
The number 51 fits into 159 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
Subtracting 153 from 159 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 51

On to step 6:
63 divided by 51 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 3831.0
If we subtract 51 from 63, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
51 can be fit into 120 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 3831.2
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 3831.23
Deduct 153 from 180 and we're left 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.

Advancing to step 9:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3831.235
If we subtract 255 from 270, we 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.

Let's proceed to step 10:
When dividing 150 by 51, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 3831.2352
Subtract 102 from 150 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
51 goes into 480 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 3831.23529
If we take 459 away from 480, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
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: 3831.235294
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 13:
When dividing 60 by 51, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 3831.2352941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 3831.23529411
If we subtract 51 from 90, we 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 final result is 3831.23529411 with a remainder of 3.9e-08.
