We look at the division of 13166329 by 578 
We want to divide 13166329 by 578.

On to step 1:
When dividing 1 by 578, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 578

Going ahead to step 2:
578 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 578

Advancing to step 3:
The number 578 fits into 131 0 times, leaving a remainder of 131.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 131, we get 131.
Grab the next digit (6) from the dividend, add it to 131, then carry on: 1316 / 578

Advancing to step 4:
578 goes into 1316 2 times with a remainder of 160.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1156 from 1316 leaves us with 160.
Grab the next digit (6) from the dividend, add it to 160, then carry on: 1606 / 578

Going ahead to step 5:
If we divide 1606 by 578, we get 2 and a remainder of 450.
The next digit of our result is 2. 
Result so far: 22.0
If we take 1156 away from 1606, we end up with 450.
Fetch the next digit (3) from the dividend, attach it to 450 and continue: 4503 / 578

On to step 6:
578 can be fit into 4503 7 times, resulting in a remainder of 457.
Write down 7 as next digit of the result. 
Result so far: 227.0
If we subtract 4046 from 4503, we get 457.
Append the next digit (2) from the dividend to 457 and continue with: 4572 / 578

Advancing to step 7:
When dividing 4572 by 578, we get 7 with a remainder of 526.
Put 7 as the next digit of the answer. 
Result so far: 2277.0
Subtracting 4046 from 4572 leaves us with 526.
Include the next digit (9) from the dividend after 526, then repeat: 5269 / 578

Going ahead to step 8:
When dividing 5269 by 578, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 22779.0
If we take 5202 away from 5269, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
578 can be fit into 670 1 times, resulting in a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 22779.1
If we take 578 away from 670, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 10:
920 divided by 578 is 1 with a remainder of 342.
The number 1 becomes the next digit in our result. 
Result so far: 22779.11
Subtract 578 from 920 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

In conclusion, the division gives 22779.11 with a balance of 0.342.
