We're dividing 56574827 by 129 
Let's see how many times 129 fits into 56574827.

Step 1:
129 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 129

Going ahead to step 2:
129 goes into 56 0 times with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 129

Going ahead to step 3:
If we divide 565 by 129, we get 4 and a remainder of 49.
The next digit of our result is 4. 
Result so far: 4.0
If we take 516 away from 565, we end up with 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 129

Step 4:
129 goes into 497 3 times with a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 387 away from 497, we end up with 110.
Take the next digit (4) from the dividend and append it to 110, then repeat: 1104 / 129

On to step 5:
If we divide 1104 by 129, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 438.0
Subtract 1032 from 1104 to get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 129

Going ahead to step 6:
129 can be fit into 728 5 times, resulting in a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 4385.0
Subtract 645 from 728 to get 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 129

Step 7:
832 divided by 129 is 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 43856.0
Subtracting 774 from 832 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 129

Advancing to step 8:
If we divide 587 by 129, we get 4 and a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 438564.0
Subtract 516 from 587 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
710 divided by 129 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 438564.5
Subtract 645 from 710 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
If we divide 650 by 129, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 438564.55
If we take 645 away from 650, we end up 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.

After the division, we end up with 438564.55 and a remainder of 0.005.
