413070 divided by 51 
Let's see how many times 51 fits into 413070.

Going ahead to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 51

Moving on to step 2:
If we divide 41 by 51, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 51

On to step 3:
413 divided by 51 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 408 from 413 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 51

Going ahead to step 4:
If we divide 50 by 51, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtract 0 from 50 to get 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 51

Let's proceed to step 5:
When dividing 507 by 51, we get 9 with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 809.0
If we subtract 459 from 507, we get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 51

Moving on to step 6:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 8099.0
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.

Advancing to step 7:
The number 51 fits into 210 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 8099.4
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 8099.41
Deduct 51 from 60 and we're left with 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 9:
When dividing 90 by 51, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 8099.411
Subtracting 51 from 90 leaves us with 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 8099.411 with a remainder of 0.0039.
