42729038 ÷ 821 
Our goal is to divide 42729038 by 821.

Moving on to step 1:
4 divided by 821 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 821

Going ahead to step 2:
821 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 821

Going ahead to step 3:
427 divided by 821 is 0 with a remainder of 427.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 427, we get 427.
Take the next digit (2) from the dividend and append it to 427, then repeat: 4272 / 821

Step 4:
4272 divided by 821 is 5 with a remainder of 167.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 167 after subtracting 4105 from 4272.
Append the next digit (9) from the dividend to 167 and continue with: 1679 / 821

Moving on to step 5:
821 goes into 1679 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 1642 from 1679 and we're left with 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 821

Step 6:
821 goes into 370 0 times with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
If we subtract 0 from 370, we get 370.
Grab the next digit (3) from the dividend, add it to 370, then carry on: 3703 / 821

On to step 7:
3703 divided by 821 is 4 with a remainder of 419.
The next digit of our result is 4. 
Result so far: 5204.0
Subtracting 3284 from 3703 leaves us with 419.
Append the next digit (8) from the dividend to 419 and continue with: 4198 / 821

Advancing to step 8:
When dividing 4198 by 821, we get 5 with a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 52045.0
If we subtract 4105 from 4198, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 9:
The number 821 fits into 930 1 times, leaving a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 52045.1
If we subtract 821 from 930, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 10:
When dividing 1090 by 821, we get 1 with a remainder of 269.
The next digit of our result is 1. 
Result so far: 52045.11
If we take 821 away from 1090, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

In conclusion, the division gives 52045.11 with a balance of 0.269.
