438436 ÷ 13 
We want to divide 438436 by 13.

Going ahead to step 1:
13 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 13

On to step 2:
13 goes into 43 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 39 from 43 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 13

On to step 3:
13 goes into 48 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 39 from 48 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 13

Advancing to step 4:
13 can be fit into 94 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 337.0
Subtracting 91 from 94 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 13

Step 5:
The number 13 fits into 33 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 3372.0
The remainder is 7 after subtracting 26 from 33.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 13

On to step 6:
When dividing 76 by 13, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 33725.0
Subtracting 65 from 76 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 13 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 33725.8
Deduct 104 from 110 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.

On to step 8:
13 goes into 60 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 33725.84
Subtract 52 from 60 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
13 goes into 80 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 33725.846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 33725.8461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 33725.84615
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 33725.846153
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 33725.8461538
Subtract 104 from 110 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.

Going ahead to step 14:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 33725.84615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 33725.84615384, with a leftover of 8e-09.
