Let's divide 66635272 by 478
We want to divide 66635272 by 478.

Going ahead to step 1:
6 divided by 478 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 478

Going ahead to step 2:
66 divided by 478 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 478

Step 3:
When dividing 666 by 478, we get 1 with a remainder of 188.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 478 from 666, we get 188.
Grab the next digit (3) from the dividend, add it to 188, then carry on: 1883 / 478

Going ahead to step 4:
When dividing 1883 by 478, we get 3 with a remainder of 449.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 449 after subtracting 1434 from 1883.
Include the next digit (5) from the dividend after 449, then repeat: 4495 / 478

Moving on to step 5:
When dividing 4495 by 478, we get 9 with a remainder of 193.
Use 9 as the next digit of our solution. 
Result so far: 139.0
The remainder is 193 after subtracting 4302 from 4495.
Fetch the next digit (2) from the dividend, attach it to 193 and continue: 1932 / 478

Advancing to step 6:
478 can be fit into 1932 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1394.0
Deduct 1912 from 1932 and we're left with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 478

Moving on to step 7:
478 goes into 207 0 times with a remainder of 207.
The next digit of our result is 0. 
Result so far: 13940.0
If we take 0 away from 207, we end up with 207.
Fetch the next digit (2) from the dividend, attach it to 207 and continue: 2072 / 478

Moving on to step 8:
When dividing 2072 by 478, we get 4 with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 139404.0
Subtracting 1912 from 2072 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
If we divide 1600 by 478, we get 3 and a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 139404.3
Subtracting 1434 from 1600 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 10:
If we divide 1660 by 478, we get 3 and a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 139404.33
The remainder is 226 after subtracting 1434 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The quotient of the division is 139404.33, and the remainder is 0.226.
