666434 ÷ 50 
We want to figure out the number of times 666434 can be divided by 50.

Advancing to step 1:
When dividing 6 by 50, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 50

Advancing to step 2:
If we divide 66 by 50, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 50 from 66 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 50

Advancing to step 3:
If we divide 166 by 50, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 150 from 166 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 50

Advancing to step 4:
50 goes into 164 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 133.0
The remainder is 14 after subtracting 150 from 164.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 50

Advancing to step 5:
143 divided by 50 is 2 with a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 1332.0
The remainder is 43 after subtracting 100 from 143.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 50

Let's proceed to step 6:
50 can be fit into 434 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 13328.0
If we take 400 away from 434, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
The number 50 fits into 340 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 13328.6
The remainder is 40 after subtracting 300 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 13328.68
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13328.68
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13328.68
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 13328.68, with a leftover of 0.0.
