Let's divide 643938 by 34
Let's see how many times 34 fits into 643938.

Moving on to step 1:
6 divided by 34 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 34

Going ahead to step 2:
If we divide 64 by 34, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 30 after subtracting 34 from 64.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 34

Step 3:
If we divide 303 by 34, we get 8 and a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 272 from 303 to get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 34

Going ahead to step 4:
If we divide 319 by 34, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
Deduct 306 from 319 and we're left with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 34

Let's proceed to step 5:
133 divided by 34 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 1893.0
Subtract 102 from 133 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 34

Advancing to step 6:
If we divide 318 by 34, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 18939.0
Subtracting 306 from 318 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 34 fits into 120 3 times, leaving a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 18939.3
Subtract 102 from 120 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
34 goes into 180 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 18939.35
The remainder is 10 after subtracting 170 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 34, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 18939.352
Deduct 68 from 100 and we're left with 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 10:
When dividing 320 by 34, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 18939.3529
The remainder is 14 after subtracting 306 from 320.
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 11:
When dividing 140 by 34, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 18939.35294
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
34 can be fit into 40 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 18939.352941
If we take 34 away from 40, we end up 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.

Step 13:
If we divide 60 by 34, we get 1 and a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 18939.3529411
Subtracting 34 from 60 leaves us with 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 18939.3529411, and the remainder is 2.6e-07.
