808190 divided by 51 
We're looking to find how many times 51 goes into 808190.

On to step 1:
51 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 51

Step 2:
80 divided by 51 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 80, we end up with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 51

Advancing to step 3:
51 can be fit into 298 5 times, resulting in a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 255 from 298, we get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 51

Advancing to step 4:
51 can be fit into 431 8 times, resulting in a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Subtracting 408 from 431 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 51

Moving on to step 5:
If we divide 239 by 51, we get 4 and a remainder of 35.
The next digit of our result is 4. 
Result so far: 1584.0
If we subtract 204 from 239, we get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 51

On to step 6:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 15846.0
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
When dividing 440 by 51, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 15846.8
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
If we divide 320 by 51, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 15846.86
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
When dividing 140 by 51, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 15846.862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 51 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 15846.8627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
The number 51 fits into 230 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 15846.86274
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 15846.862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
When dividing 50 by 51, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 15846.862745
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 15846.86274509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 15846.86274509 with a balance of 4.1e-08.
