We divide 40090 by 51
Our goal is to divide 40090 by 51.

On to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 51

Going ahead to step 2:
If we divide 40 by 51, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 51

Going ahead to step 3:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 357 from 400 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 51

Going ahead to step 4:
The number 51 fits into 439 8 times, leaving a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 408 from 439 leaves us with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 51

Going ahead to step 5:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 6:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 786.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
51 goes into 400 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 786.07
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
If we divide 430 by 51, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 786.078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
51 goes into 220 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 786.0784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 51, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 786.07843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
70 divided by 51 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 786.078431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
If we divide 190 by 51, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 786.0784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
51 goes into 370 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 786.07843137
If we take 357 away from 370, we end up 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.

In conclusion, the division gives 786.07843137 with a balance of 1.3e-08.
