16601290 divided by 478 
Our goal is to divide 16601290 by 478.

Step 1:
If we divide 1 by 478, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 478

Let's proceed to step 2:
16 divided by 478 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 478

Let's proceed to step 3:
When dividing 166 by 478, we get 0 with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Include the next digit (0) from the dividend after 166, then repeat: 1660 / 478

Advancing to step 4:
1660 divided by 478 is 3 with a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1434 away from 1660, we end up with 226.
Take the next digit (1) from the dividend and append it to 226, then repeat: 2261 / 478

Step 5:
When dividing 2261 by 478, we get 4 with a remainder of 349.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 1912 away from 2261, we end up with 349.
Bring next digit (2) of the dividend behind the 349 and repeat the process: 3492 / 478

On to step 6:
478 goes into 3492 7 times with a remainder of 146.
The next digit of our result is 7. 
Result so far: 347.0
If we take 3346 away from 3492, we end up with 146.
Include the next digit (9) from the dividend after 146, then repeat: 1469 / 478

Going ahead to step 7:
478 goes into 1469 3 times with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 3473.0
If we take 1434 away from 1469, we end up with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 478

On to step 8:
The number 478 fits into 350 0 times, leaving a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 34730.0
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 9:
478 can be fit into 3500 7 times, resulting in a remainder of 154.
Use 7 as the next digit of our solution. 
Result so far: 34730.7
Subtract 3346 from 3500 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 10:
478 goes into 1540 3 times with a remainder of 106.
The next digit of our result is 3. 
Result so far: 34730.73
Subtract 1434 from 1540 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
478 goes into 1060 2 times with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 34730.732
Deduct 956 from 1060 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
478 can be fit into 1040 2 times, resulting in a remainder of 84.
The next digit of our result is 2. 
Result so far: 34730.7322
If we subtract 956 from 1040, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 34730.7322 with a remainder of 0.00084.
