We're dividing 360640 by 51 
Let's see how many times 51 fits into 360640.

Let's proceed to step 1:
51 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 51

Advancing to step 2:
If we divide 36 by 51, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 51

On to step 3:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 357 away from 360, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 51

Advancing to step 4:
36 divided by 51 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 36, we end up with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 51

Going ahead to step 5:
If we divide 364 by 51, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 707.0
Deduct 357 from 364 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 51

Step 6:
51 goes into 70 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 7071.0
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 51, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 7071.3
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
When dividing 370 by 51, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7071.37
Deduct 357 from 370 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
51 goes into 130 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7071.372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
280 divided by 51 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7071.3725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
51 goes into 250 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 7071.37254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
When dividing 460 by 51, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 7071.372549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
When dividing 10 by 51, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7071.372549
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
When dividing 100 by 51, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 7071.37254901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 7071.37254901 with a remainder of 4.9e-08.
