We're dividing 80976428 by 436 
Our goal is to divide 80976428 by 436.

Advancing to step 1:
8 divided by 436 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 436

Advancing to step 2:
If we divide 80 by 436, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 436

Step 3:
809 divided by 436 is 1 with a remainder of 373.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 436 from 809 and we're left with 373.
Grab the next digit (7) from the dividend, add it to 373, then carry on: 3737 / 436

Advancing to step 4:
When dividing 3737 by 436, we get 8 with a remainder of 249.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 3488 from 3737 to get 249.
Fetch the next digit (6) from the dividend, attach it to 249 and continue: 2496 / 436

On to step 5:
If we divide 2496 by 436, we get 5 and a remainder of 316.
The next digit of our result is 5. 
Result so far: 185.0
The remainder is 316 after subtracting 2180 from 2496.
Append the next digit (4) from the dividend to 316 and continue with: 3164 / 436

Step 6:
When dividing 3164 by 436, we get 7 with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 1857.0
Subtracting 3052 from 3164 leaves us with 112.
Include the next digit (2) from the dividend after 112, then repeat: 1122 / 436

Going ahead to step 7:
436 goes into 1122 2 times with a remainder of 250.
Use 2 as the next digit of our solution. 
Result so far: 18572.0
The remainder is 250 after subtracting 872 from 1122.
Bring next digit (8) of the dividend behind the 250 and repeat the process: 2508 / 436

Step 8:
436 goes into 2508 5 times with a remainder of 328.
Use 5 as the next digit of our solution. 
Result so far: 185725.0
The remainder is 328 after subtracting 2180 from 2508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 9:
When dividing 3280 by 436, we get 7 with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 185725.7
Subtracting 3052 from 3280 leaves us 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.

Let's proceed to step 10:
The number 436 fits into 2280 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 185725.75
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.

On to step 11:
When dividing 1000 by 436, we get 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 185725.752
Subtracting 872 from 1000 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
If we divide 1280 by 436, we get 2 and a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 185725.7522
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.

The final result is 185725.7522 with a remainder of 0.00408.
