360573 ÷ 51 
We want to figure out the number of times 360573 can be divided by 51.

Let's proceed to step 1:
51 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 51

Moving on to step 2:
51 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 51

On to step 3:
If we divide 360 by 51, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 3 after subtracting 357 from 360.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 51

Step 4:
When dividing 35 by 51, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we subtract 0 from 35, we get 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 51

Going ahead to step 5:
51 goes into 357 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 707.0
Subtract 357 from 357 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 51

Going ahead to step 6:
51 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 7070.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
51 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7070.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
51 can be fit into 300 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 7070.05
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 7070.058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 51, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 7070.0588
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 7070.0588 with a remainder of 0.00012.
