We look at the division of 210434 by 80 
Let's see how many times 80 fits into 210434.

Advancing to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 80

On to step 2:
80 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 80

Step 3:
80 goes into 210 2 times with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 160 away from 210, we end up with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 80

Going ahead to step 4:
80 can be fit into 504 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 24 after subtracting 480 from 504.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 80

Moving on to step 5:
243 divided by 80 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 263.0
The remainder is 3 after subtracting 240 from 243.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 80

On to step 6:
80 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 2630.0
Subtracting 0 from 34 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
The number 80 fits into 340 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 2630.4
If we take 320 away from 340, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 80, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2630.42
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2630.425
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2630.425
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2630.425
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2630.425 with a balance of 0.0.
