We're dividing 643244 by 34 
Let's see how many times 34 fits into 643244.

Let's proceed to 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
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 34

Step 2:
34 goes into 64 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 34 from 64 and we're left with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 34

Going ahead to step 3:
The number 34 fits into 303 8 times, leaving a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 272 from 303, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 34

Moving on to step 4:
The number 34 fits into 312 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
If we subtract 306 from 312, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 34

Step 5:
If we divide 64 by 34, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1891.0
If we subtract 34 from 64, we get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 34

Moving on to step 6:
When dividing 304 by 34, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 18918.0
If we subtract 272 from 304, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
34 goes into 320 9 times with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 18918.9
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
34 can be fit into 140 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 18918.94
If we subtract 136 from 140, we 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.

Going ahead to step 9:
The number 34 fits into 40 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 18918.941
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
If we divide 60 by 34, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 18918.9411
If we subtract 34 from 60, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 18918.9411, and the remainder is 0.00026.
