Let's divide 135243 by 34
We want to figure out the number of times 135243 can be divided by 34.

Let's proceed to step 1:
The number 34 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 34

Going ahead to step 2:
34 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 34

Let's proceed to step 3:
135 divided by 34 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 102 from 135, we get 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 34

Let's proceed to step 4:
34 goes into 332 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 306 away from 332, we end up with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 34

Let's proceed to step 5:
When dividing 264 by 34, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 397.0
Deduct 238 from 264 and we're left with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 34

Advancing to step 6:
The number 34 fits into 263 7 times, leaving a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 3977.0
Subtracting 238 from 263 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
The number 34 fits into 250 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 3977.7
Subtract 238 from 250 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 34, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 3977.73
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 9:
34 can be fit into 180 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 3977.735
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.

On to step 10:
34 goes into 100 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3977.7352
Subtract 68 from 100 to 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 11:
When dividing 320 by 34, we get 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 3977.73529
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 12:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 3977.735294
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.

Step 13:
34 goes into 40 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 3977.7352941
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.

Step 14:
The number 34 fits into 60 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 3977.73529411
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 final result is 3977.73529411 with a remainder of 2.6e-08.
