We look at the division of 13859688 by 436 
Let's see how many times 436 fits into 13859688.

Step 1:
436 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 436

Moving on to step 2:
13 divided by 436 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 436

Advancing to step 3:
If we divide 138 by 436, we get 0 and a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Include the next digit (5) from the dividend after 138, then repeat: 1385 / 436

Moving on to step 4:
When dividing 1385 by 436, we get 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1308 from 1385 and we're left with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 436

Going ahead to step 5:
436 can be fit into 779 1 times, resulting in a remainder of 343.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 436 from 779 to get 343.
Take the next digit (6) from the dividend and append it to 343, then repeat: 3436 / 436

On to step 6:
If we divide 3436 by 436, we get 7 and a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Deduct 3052 from 3436 and we're left with 384.
Grab the next digit (8) from the dividend, add it to 384, then carry on: 3848 / 436

On to step 7:
3848 divided by 436 is 8 with a remainder of 360.
The next digit of our result is 8. 
Result so far: 3178.0
Subtracting 3488 from 3848 leaves us with 360.
Grab the next digit (8) from the dividend, add it to 360, then carry on: 3608 / 436

Let's proceed to step 8:
436 can be fit into 3608 8 times, resulting in a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 31788.0
If we take 3488 away from 3608, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 9:
If we divide 1200 by 436, we get 2 and a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 31788.2
The remainder is 328 after subtracting 872 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
436 goes into 3280 7 times with a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 31788.27
Deduct 3052 from 3280 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 11:
If we divide 2280 by 436, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 31788.275
Subtract 2180 from 2280 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
1000 divided by 436 is 2 with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 31788.2752
If we subtract 872 from 1000, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
1280 divided by 436 is 2 with a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 31788.27522
If we subtract 872 from 1280, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

After the division, we end up with 31788.27522 and a remainder of 0.000408.
