We're dividing 339807 by 66 
We're looking to find how many times 66 goes into 339807.

Moving on to step 1:
3 divided by 66 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 66

Advancing to step 2:
33 divided by 66 is 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 66

On to step 3:
66 can be fit into 339 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 330 from 339 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 66

Moving on to step 4:
If we divide 98 by 66, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 32 after subtracting 66 from 98.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 66

On to step 5:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 514.0
If we subtract 264 from 320, we get 56.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 66

Moving on to step 6:
66 can be fit into 567 8 times, resulting in a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 5148.0
If we subtract 528 from 567, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
66 goes into 390 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 5148.5
If we subtract 330 from 390, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 66, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 5148.59
The remainder is 6 after subtracting 594 from 600.
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 9:
66 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 5148.59
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
66 goes into 600 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5148.5909
The remainder is 6 after subtracting 594 from 600.
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 11:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5148.5909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
66 goes into 600 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 5148.590909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
66 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5148.590909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 5148.59090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 5148.59090909 with a balance of 6e-09.
