Let's divide 81386222 by 456
Our goal is to divide 81386222 by 456.

Advancing to step 1:
When dividing 8 by 456, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 456

Moving on to step 2:
The number 456 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 456

Step 3:
The number 456 fits into 813 1 times, leaving a remainder of 357.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 456 from 813 and we're left with 357.
Take the next digit (8) from the dividend and append it to 357, then repeat: 3578 / 456

Advancing to step 4:
If we divide 3578 by 456, we get 7 and a remainder of 386.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 3192 from 3578 and we're left with 386.
Bring next digit (6) of the dividend behind the 386 and repeat the process: 3866 / 456

Moving on to step 5:
The number 456 fits into 3866 8 times, leaving a remainder of 218.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 218 after subtracting 3648 from 3866.
Include the next digit (2) from the dividend after 218, then repeat: 2182 / 456

Step 6:
The number 456 fits into 2182 4 times, leaving a remainder of 358.
The number 4 becomes the next digit in our result. 
Result so far: 1784.0
Subtracting 1824 from 2182 leaves us with 358.
Grab the next digit (2) from the dividend, add it to 358, then carry on: 3582 / 456

Step 7:
456 goes into 3582 7 times with a remainder of 390.
Write down 7 as next digit of the result. 
Result so far: 17847.0
Subtracting 3192 from 3582 leaves us with 390.
Bring next digit (2) of the dividend behind the 390 and repeat the process: 3902 / 456

Moving on to step 8:
When dividing 3902 by 456, we get 8 with a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 178478.0
Deduct 3648 from 3902 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 9:
The number 456 fits into 2540 5 times, leaving a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 178478.5
Deduct 2280 from 2540 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
When dividing 2600 by 456, we get 5 with a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 178478.55
If we subtract 2280 from 2600, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 178478.55, with a leftover of 0.32.
