We look at the division of 81424203 by 945 
Our goal is to divide 81424203 by 945.

Going ahead to step 1:
The number 945 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 945

Step 2:
81 divided by 945 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 945

Step 3:
If we divide 814 by 945, we get 0 and a remainder of 814.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 814, we end up with 814.
Append the next digit (2) from the dividend to 814 and continue with: 8142 / 945

Advancing to step 4:
945 can be fit into 8142 8 times, resulting in a remainder of 582.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7560 from 8142 to get 582.
Include the next digit (4) from the dividend after 582, then repeat: 5824 / 945

Moving on to step 5:
945 goes into 5824 6 times with a remainder of 154.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 5670 from 5824, we get 154.
Bring next digit (2) of the dividend behind the 154 and repeat the process: 1542 / 945

Let's proceed to step 6:
945 can be fit into 1542 1 times, resulting in a remainder of 597.
Use 1 as the next digit of our solution. 
Result so far: 861.0
Deduct 945 from 1542 and we're left with 597.
Take the next digit (0) from the dividend and append it to 597, then repeat: 5970 / 945

Going ahead to step 7:
The number 945 fits into 5970 6 times, leaving a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 8616.0
If we subtract 5670 from 5970, we get 300.
Grab the next digit (3) from the dividend, add it to 300, then carry on: 3003 / 945

Moving on to step 8:
If we divide 3003 by 945, we get 3 and a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 86163.0
Subtract 2835 from 3003 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
If we divide 1680 by 945, we get 1 and a remainder of 735.
The number 1 becomes the next digit in our result. 
Result so far: 86163.1
If we subtract 945 from 1680, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

On to step 10:
The number 945 fits into 7350 7 times, leaving a remainder of 735.
Use 7 as the next digit of our solution. 
Result so far: 86163.17
Subtract 6615 from 7350 to get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Going ahead to step 11:
If we divide 7350 by 945, we get 7 and a remainder of 735.
The number 7 becomes the next digit in our result. 
Result so far: 86163.177
Subtract 6615 from 7350 to get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

The final outcome is 86163.177, with a leftover of 0.0735.
