We're dividing 40155532 by 486 
We want to divide 40155532 by 486.

Going ahead to step 1:
When dividing 4 by 486, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 486

Going ahead to step 2:
If we divide 40 by 486, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 486

Step 3:
401 divided by 486 is 0 with a remainder of 401.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Take the next digit (5) from the dividend and append it to 401, then repeat: 4015 / 486

Step 4:
When dividing 4015 by 486, we get 8 with a remainder of 127.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 3888 from 4015 and we're left with 127.
Bring next digit (5) of the dividend behind the 127 and repeat the process: 1275 / 486

Moving on to step 5:
When dividing 1275 by 486, we get 2 with a remainder of 303.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
The remainder is 303 after subtracting 972 from 1275.
Fetch the next digit (5) from the dividend, attach it to 303 and continue: 3035 / 486

Step 6:
3035 divided by 486 is 6 with a remainder of 119.
Put 6 as the next digit of the answer. 
Result so far: 826.0
If we take 2916 away from 3035, we end up with 119.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 486

Moving on to step 7:
1193 divided by 486 is 2 with a remainder of 221.
Write down 2 as next digit of the result. 
Result so far: 8262.0
The remainder is 221 after subtracting 972 from 1193.
Grab the next digit (2) from the dividend, add it to 221, then carry on: 2212 / 486

Going ahead to step 8:
The number 486 fits into 2212 4 times, leaving a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 82624.0
Subtracting 1944 from 2212 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 9:
When dividing 2680 by 486, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 82624.5
If we subtract 2430 from 2680, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
2500 divided by 486 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 82624.55
Deduct 2430 from 2500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 82624.55, with a leftover of 0.07.
