352866 divided by 51 
Let's see how many times 51 fits into 352866.

Going ahead to step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 51

Going ahead to step 2:
The number 51 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 51

Step 3:
When dividing 352 by 51, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 306 from 352 to get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 51

Advancing to step 4:
468 divided by 51 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 459 from 468, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 51

Step 5:
When dividing 96 by 51, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 691.0
If we take 51 away from 96, we end up with 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 51

Let's proceed to step 6:
The number 51 fits into 456 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 6918.0
If we subtract 408 from 456, we 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 7:
The number 51 fits into 480 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 6918.9
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.

Step 8:
The number 51 fits into 210 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 6918.94
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.

On to step 9:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 6918.941
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.

Step 10:
When dividing 90 by 51, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 6918.9411
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.

Our division results in 6918.9411 with a remaining 0.00039.
