We divide 42811185 by 869
Our goal is to divide 42811185 by 869.

Moving on to step 1:
If we divide 4 by 869, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 869

Moving on to step 2:
The number 869 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 869

Step 3:
869 can be fit into 428 0 times, resulting in a remainder of 428.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Include the next digit (1) from the dividend after 428, then repeat: 4281 / 869

Let's proceed to step 4:
If we divide 4281 by 869, we get 4 and a remainder of 805.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3476 from 4281, we get 805.
Fetch the next digit (1) from the dividend, attach it to 805 and continue: 8051 / 869

Step 5:
8051 divided by 869 is 9 with a remainder of 230.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 230 after subtracting 7821 from 8051.
Fetch the next digit (1) from the dividend, attach it to 230 and continue: 2301 / 869

Going ahead to step 6:
2301 divided by 869 is 2 with a remainder of 563.
Put 2 as the next digit of the answer. 
Result so far: 492.0
Deduct 1738 from 2301 and we're left with 563.
Take the next digit (8) from the dividend and append it to 563, then repeat: 5638 / 869

Advancing to step 7:
5638 divided by 869 is 6 with a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 4926.0
If we subtract 5214 from 5638, we get 424.
Grab the next digit (5) from the dividend, add it to 424, then carry on: 4245 / 869

On to step 8:
When dividing 4245 by 869, we get 4 with a remainder of 769.
Use 4 as the next digit of our solution. 
Result so far: 49264.0
If we take 3476 away from 4245, we end up with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Step 9:
869 goes into 7690 8 times with a remainder of 738.
Record the quotient 8 as the next digit in the result. 
Result so far: 49264.8
Deduct 6952 from 7690 and we're left with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Step 10:
If we divide 7380 by 869, we get 8 and a remainder of 428.
Put 8 as the next digit of the answer. 
Result so far: 49264.88
If we take 6952 away from 7380, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final result is 49264.88 with a remainder of 0.428.
