We look at the division of 57290429 by 866 
We want to divide 57290429 by 866.

Moving on to step 1:
866 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 866

Advancing to step 2:
866 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 866

Step 3:
572 divided by 866 is 0 with a remainder of 572.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 572 and we're left with 572.
Append the next digit (9) from the dividend to 572 and continue with: 5729 / 866

Let's proceed to step 4:
If we divide 5729 by 866, we get 6 and a remainder of 533.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 533 after subtracting 5196 from 5729.
Include the next digit (0) from the dividend after 533, then repeat: 5330 / 866

Going ahead to step 5:
866 can be fit into 5330 6 times, resulting in a remainder of 134.
The next digit of our result is 6. 
Result so far: 66.0
The remainder is 134 after subtracting 5196 from 5330.
Bring next digit (4) of the dividend behind the 134 and repeat the process: 1344 / 866

Going ahead to step 6:
When dividing 1344 by 866, we get 1 with a remainder of 478.
The next digit of our result is 1. 
Result so far: 661.0
If we subtract 866 from 1344, we get 478.
Take the next digit (2) from the dividend and append it to 478, then repeat: 4782 / 866

Let's proceed to step 7:
The number 866 fits into 4782 5 times, leaving a remainder of 452.
Use 5 as the next digit of our solution. 
Result so far: 6615.0
Subtracting 4330 from 4782 leaves us with 452.
Grab the next digit (9) from the dividend, add it to 452, then carry on: 4529 / 866

Let's proceed to step 8:
If we divide 4529 by 866, we get 5 and a remainder of 199.
Record the quotient 5 as the next digit in the result. 
Result so far: 66155.0
Deduct 4330 from 4529 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 9:
When dividing 1990 by 866, we get 2 with a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 66155.2
If we take 1732 away from 1990, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
When dividing 2580 by 866, we get 2 with a remainder of 848.
Record the quotient 2 as the next digit in the result. 
Result so far: 66155.22
If we take 1732 away from 2580, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

In conclusion, the division gives 66155.22 with a balance of 0.848.
