30434387 divided by 436 
Our goal is to divide 30434387 by 436.

Let's proceed to step 1:
When dividing 3 by 436, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 436

On to step 2:
The number 436 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 436

Advancing to step 3:
The number 436 fits into 304 0 times, leaving a remainder of 304.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 304 leaves us with 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 436

Moving on to step 4:
The number 436 fits into 3043 6 times, leaving a remainder of 427.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 427 after subtracting 2616 from 3043.
Bring next digit (4) of the dividend behind the 427 and repeat the process: 4274 / 436

On to step 5:
When dividing 4274 by 436, we get 9 with a remainder of 350.
Use 9 as the next digit of our solution. 
Result so far: 69.0
If we take 3924 away from 4274, we end up with 350.
Grab the next digit (3) from the dividend, add it to 350, then carry on: 3503 / 436

Moving on to step 6:
3503 divided by 436 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 698.0
Deduct 3488 from 3503 and we're left with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 436

On to step 7:
436 goes into 158 0 times with a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 6980.0
Subtract 0 from 158 to get 158.
Bring next digit (7) of the dividend behind the 158 and repeat the process: 1587 / 436

Let's proceed to step 8:
436 goes into 1587 3 times with a remainder of 279.
Use 3 as the next digit of our solution. 
Result so far: 69803.0
If we subtract 1308 from 1587, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 9:
436 goes into 2790 6 times with a remainder of 174.
The next digit of our result is 6. 
Result so far: 69803.6
If we take 2616 away from 2790, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 10:
436 goes into 1740 3 times with a remainder of 432.
Use 3 as the next digit of our solution. 
Result so far: 69803.63
If we take 1308 away from 1740, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 11:
The number 436 fits into 4320 9 times, leaving a remainder of 396.
Write down 9 as next digit of the result. 
Result so far: 69803.639
The remainder is 396 after subtracting 3924 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 12:
If we divide 3960 by 436, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 69803.6399
The remainder is 36 after subtracting 3924 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 69803.6399 with a balance of 0.00036.
