We look at the division of 303478 by 70 
We want to figure out the number of times 303478 can be divided by 70.

Going ahead to step 1:
The number 70 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 70

Advancing to step 2:
70 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 70

On to step 3:
303 divided by 70 is 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
If we take 280 away from 303, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 70

Moving on to step 4:
The number 70 fits into 234 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 210 from 234 leaves us with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 70

Going ahead to step 5:
If we divide 247 by 70, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
If we subtract 210 from 247, we get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 70

Let's proceed to step 6:
70 goes into 378 5 times with a remainder of 28.
The next digit of our result is 5. 
Result so far: 4335.0
Deduct 350 from 378 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
70 goes into 280 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4335.4
Subtracting 280 from 280 leaves us 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.

Let's proceed to step 8:
When dividing 0 by 70, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4335.4
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.

Advancing to step 9:
If we divide 0 by 70, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4335.4
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.

The final result is 4335.4 with a remainder of 0.0.
