We divide 351406 by 80
We want to divide 351406 by 80.

Let's proceed to step 1:
80 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 80

Advancing to step 2:
If we divide 35 by 80, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 80

Advancing to step 3:
When dividing 351 by 80, we get 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 320 away from 351, we end up with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 80

Moving on to step 4:
If we divide 314 by 80, we get 3 and a remainder of 74.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 240 from 314 to get 74.
Take the next digit (0) from the dividend and append it to 74, then repeat: 740 / 80

Going ahead to step 5:
When dividing 740 by 80, we get 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 720 from 740 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 80

Let's proceed to step 6:
80 goes into 206 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 4392.0
Deduct 160 from 206 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
80 can be fit into 460 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4392.5
Subtracting 400 from 460 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 4392.57
Deduct 560 from 600 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.

Going ahead to step 9:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4392.575
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.

Advancing to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4392.575
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.

Step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4392.575
If we subtract 0 from 0, we 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.

In conclusion, the division gives 4392.575 with a balance of 0.0.
