We look at the division of 669951 by 34 
We want to figure out the number of times 669951 can be divided by 34.

Step 1:
34 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 34

Let's proceed to step 2:
The number 34 fits into 66 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 34 from 66 and we're left with 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 34

On to step 3:
The number 34 fits into 329 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 306 from 329 leaves us with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 34

Step 4:
34 can be fit into 239 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
Deduct 238 from 239 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 34

Moving on to step 5:
When dividing 15 by 34, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 1970.0
Subtract 0 from 15 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 34

Moving on to step 6:
If we divide 151 by 34, we get 4 and a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 19704.0
The remainder is 15 after subtracting 136 from 151.
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 7:
34 can be fit into 150 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 19704.4
Subtracting 136 from 150 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
34 goes into 140 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 19704.44
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 19704.44 with a remainder of 0.004.
