339090 ÷ 51 
We want to figure out the number of times 339090 can be divided by 51.

Moving on to step 1:
The number 51 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 51

Let's proceed to step 2:
33 divided by 51 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 51

On to step 3:
339 divided by 51 is 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 306 from 339 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 51

Let's proceed to step 4:
330 divided by 51 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 306 from 330, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 51

Going ahead to step 5:
When dividing 249 by 51, we get 4 with a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 664.0
If we subtract 204 from 249, we get 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 51

Step 6:
450 divided by 51 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 6648.0
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 6648.8
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 51 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 6648.82
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 51, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 6648.823
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.

Going ahead to 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: 6648.8235
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.

On to step 11:
51 can be fit into 150 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 6648.82352
Deduct 102 from 150 and we're left 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.

On to step 12:
When dividing 480 by 51, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 6648.823529
Subtracting 459 from 480 leaves us 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 13:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 6648.8235294
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.

On to step 14:
If we divide 60 by 51, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 6648.82352941
If we subtract 51 from 60, we 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.

After the division, we end up with 6648.82352941 and a remainder of 9e-09.
