Let's divide 123965 by 34
We want to divide 123965 by 34.

Step 1:
34 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 34

Advancing to step 2:
34 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 34

Step 3:
The number 34 fits into 123 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 102 from 123 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 34

Moving on to step 4:
When dividing 219 by 34, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 204 from 219, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 34

Step 5:
If we divide 156 by 34, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 364.0
If we take 136 away from 156, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 34

Going ahead to step 6:
205 divided by 34 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 3646.0
The remainder is 1 after subtracting 204 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
34 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3646.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 34, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 3646.02
If we subtract 68 from 100, 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 9:
When dividing 320 by 34, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 3646.029
Deduct 306 from 320 and we're left 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 10:
140 divided by 34 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 3646.0294
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.

Moving on to step 11:
When dividing 40 by 34, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 3646.02941
Subtract 34 from 40 to get 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 12:
The number 34 fits into 60 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 3646.029411
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.

Our division results in 3646.029411 with a remaining 2.6e-06.
