Let's divide 609390 by 51
We're looking to find how many times 51 goes into 609390.

Step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 51

Moving on to step 2:
60 divided by 51 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 51 from 60 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 51

Let's proceed to step 3:
51 goes into 99 1 times with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 51 from 99 to get 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 51

Step 4:
51 can be fit into 483 9 times, resulting in a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 119.0
The remainder is 24 after subtracting 459 from 483.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 51

Step 5:
The number 51 fits into 249 4 times, leaving a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 1194.0
If we subtract 204 from 249, we get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 51

On to step 6:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 11948.0
If we subtract 408 from 450, we 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.

Step 7:
If we divide 420 by 51, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11948.8
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
51 can be fit into 120 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 11948.82
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
51 goes into 180 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 11948.823
If we subtract 153 from 180, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 11948.8235
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
If we divide 150 by 51, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 11948.82352
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
When dividing 480 by 51, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 11948.823529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
51 goes into 210 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 11948.8235294
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.

Advancing to step 14:
60 divided by 51 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 11948.82352941
If we take 51 away from 60, we end up 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.

In conclusion, the division gives 11948.82352941 with a balance of 9e-09.
