We look at the division of 13404586 by 436 
We're looking to find how many times 436 goes into 13404586.

Going ahead to step 1:
436 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 436

On to step 2:
When dividing 13 by 436, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 436

Let's proceed to step 3:
The number 436 fits into 134 0 times, leaving a remainder of 134.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 134 and we're left with 134.
Take the next digit (0) from the dividend and append it to 134, then repeat: 1340 / 436

On to step 4:
The number 436 fits into 1340 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1308 from 1340, we get 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 436

Advancing to step 5:
324 divided by 436 is 0 with a remainder of 324.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 324, we end up with 324.
Take the next digit (5) from the dividend and append it to 324, then repeat: 3245 / 436

Let's proceed to step 6:
436 can be fit into 3245 7 times, resulting in a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 307.0
The remainder is 193 after subtracting 3052 from 3245.
Grab the next digit (8) from the dividend, add it to 193, then carry on: 1938 / 436

Moving on to step 7:
When dividing 1938 by 436, we get 4 with a remainder of 194.
Put 4 as the next digit of the answer. 
Result so far: 3074.0
The remainder is 194 after subtracting 1744 from 1938.
Bring next digit (6) of the dividend behind the 194 and repeat the process: 1946 / 436

Let's proceed to step 8:
1946 divided by 436 is 4 with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 30744.0
If we take 1744 away from 1946, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 9:
If we divide 2020 by 436, we get 4 and a remainder of 276.
The next digit of our result is 4. 
Result so far: 30744.4
The remainder is 276 after subtracting 1744 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 10:
436 can be fit into 2760 6 times, resulting in a remainder of 144.
The next digit of our result is 6. 
Result so far: 30744.46
If we take 2616 away from 2760, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 11:
If we divide 1440 by 436, we get 3 and a remainder of 132.
The next digit of our result is 3. 
Result so far: 30744.463
Subtract 1308 from 1440 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 12:
436 goes into 1320 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 30744.4633
The remainder is 12 after subtracting 1308 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 30744.4633 with a balance of 0.00012.
