358470 ÷ 80 
We want to figure out the number of times 358470 can be divided by 80.

On 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.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 80

Let's proceed to step 2:
The number 80 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 80

Advancing to step 3:
80 goes into 358 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 320 from 358 and we're left with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 80

Advancing to step 4:
The number 80 fits into 384 4 times, leaving a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 320 from 384 leaves us with 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 80

On to step 5:
If we divide 647 by 80, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
The remainder is 7 after subtracting 640 from 647.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 80

Advancing to step 6:
If we divide 70 by 80, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 4480.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
700 divided by 80 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 4480.8
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 4480.87
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 4480.875
Deduct 400 from 400 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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4480.875
If we take 0 away from 0, 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 11:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4480.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4480.875 and a remainder of 0.0.
