We divide 39210074 by 478
We want to divide 39210074 by 478.

Moving on to step 1:
478 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 478

Moving on to step 2:
If we divide 39 by 478, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 478

Let's proceed to step 3:
The number 478 fits into 392 0 times, leaving a remainder of 392.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 392 and we're left with 392.
Fetch the next digit (1) from the dividend, attach it to 392 and continue: 3921 / 478

On to step 4:
3921 divided by 478 is 8 with a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 3824 away from 3921, we end up with 97.
Grab the next digit (0) from the dividend, add it to 97, then carry on: 970 / 478

Moving on to step 5:
970 divided by 478 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 82.0
The remainder is 14 after subtracting 956 from 970.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 478

Moving on to step 6:
When dividing 140 by 478, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we subtract 0 from 140, we get 140.
Fetch the next digit (7) from the dividend, attach it to 140 and continue: 1407 / 478

On to step 7:
The number 478 fits into 1407 2 times, leaving a remainder of 451.
Put 2 as the next digit of the answer. 
Result so far: 8202.0
If we subtract 956 from 1407, we get 451.
Bring next digit (4) of the dividend behind the 451 and repeat the process: 4514 / 478

Advancing to step 8:
When dividing 4514 by 478, we get 9 with a remainder of 212.
Record the quotient 9 as the next digit in the result. 
Result so far: 82029.0
If we subtract 4302 from 4514, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
The number 478 fits into 2120 4 times, leaving a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 82029.4
If we subtract 1912 from 2120, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 10:
If we divide 2080 by 478, we get 4 and a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 82029.44
Subtract 1912 from 2080 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 82029.44, with a leftover of 0.168.
