578429 ÷ 55 
Our goal is to divide 578429 by 55.

Step 1:
5 divided by 55 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 55

Let's proceed to step 2:
55 can be fit into 57 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 55 from 57, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 55

Advancing to step 3:
The number 55 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 28 to get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 55

Moving on to step 4:
The number 55 fits into 284 5 times, leaving a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtract 275 from 284 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 55

On to step 5:
If we divide 92 by 55, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
Subtract 55 from 92 to get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 55

Step 6:
When dividing 379 by 55, we get 6 with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 10516.0
Deduct 330 from 379 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
55 goes into 490 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 10516.8
Subtract 440 from 490 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 55, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 10516.89
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
When dividing 50 by 55, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10516.89
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 55 fits into 500 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 10516.8909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10516.8909
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 55, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 10516.890909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
When dividing 50 by 55, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10516.890909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 55, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 10516.89090909
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 10516.89090909, with a leftover of 5e-09.
