30485778 divided by 478 
We want to figure out the number of times 30485778 can be divided by 478.

Moving on to step 1:
478 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 478

Advancing to step 2:
30 divided by 478 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 478

Advancing to step 3:
When dividing 304 by 478, we get 0 with a remainder of 304.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 304, we get 304.
Append the next digit (8) from the dividend to 304 and continue with: 3048 / 478

Step 4:
The number 478 fits into 3048 6 times, leaving a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 180 after subtracting 2868 from 3048.
Take the next digit (5) from the dividend and append it to 180, then repeat: 1805 / 478

Advancing to step 5:
478 goes into 1805 3 times with a remainder of 371.
Write down 3 as next digit of the result. 
Result so far: 63.0
If we take 1434 away from 1805, we end up with 371.
Grab the next digit (7) from the dividend, add it to 371, then carry on: 3717 / 478

On to step 6:
3717 divided by 478 is 7 with a remainder of 371.
The next digit of our result is 7. 
Result so far: 637.0
The remainder is 371 after subtracting 3346 from 3717.
Take the next digit (7) from the dividend and append it to 371, then repeat: 3717 / 478

On to step 7:
If we divide 3717 by 478, we get 7 and a remainder of 371.
The next digit of our result is 7. 
Result so far: 6377.0
If we take 3346 away from 3717, we end up with 371.
Take the next digit (8) from the dividend and append it to 371, then repeat: 3718 / 478

Let's proceed to step 8:
The number 478 fits into 3718 7 times, leaving a remainder of 372.
Write down 7 as next digit of the result. 
Result so far: 63777.0
If we take 3346 away from 3718, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 9:
478 can be fit into 3720 7 times, resulting in a remainder of 374.
Record the quotient 7 as the next digit in the result. 
Result so far: 63777.7
Subtract 3346 from 3720 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 10:
When dividing 3740 by 478, we get 7 with a remainder of 394.
Write down 7 as next digit of the result. 
Result so far: 63777.77
If we subtract 3346 from 3740, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

After the division, we end up with 63777.77 and a remainder of 0.394.
