81504164 ÷ 143 
We're looking to find how many times 143 goes into 81504164.

Going ahead to step 1:
8 divided by 143 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 143

Moving on to step 2:
143 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 143

Moving on to step 3:
143 goes into 815 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 715 from 815 leaves us with 100.
Include the next digit (0) from the dividend after 100, then repeat: 1000 / 143

On to step 4:
When dividing 1000 by 143, we get 6 with a remainder of 142.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 858 from 1000 to get 142.
Grab the next digit (4) from the dividend, add it to 142, then carry on: 1424 / 143

Step 5:
If we divide 1424 by 143, we get 9 and a remainder of 137.
Record the quotient 9 as the next digit in the result. 
Result so far: 569.0
Subtract 1287 from 1424 to get 137.
Include the next digit (1) from the dividend after 137, then repeat: 1371 / 143

Advancing to step 6:
If we divide 1371 by 143, we get 9 and a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 5699.0
If we take 1287 away from 1371, we end up with 84.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 143

Going ahead to step 7:
The number 143 fits into 846 5 times, leaving a remainder of 131.
Write down 5 as next digit of the result. 
Result so far: 56995.0
Subtracting 715 from 846 leaves us with 131.
Include the next digit (4) from the dividend after 131, then repeat: 1314 / 143

Let's proceed to step 8:
If we divide 1314 by 143, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 569959.0
Deduct 1287 from 1314 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 143 fits into 270 1 times, leaving a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 569959.1
Subtract 143 from 270 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 10:
1270 divided by 143 is 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 569959.18
Subtract 1144 from 1270 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 11:
The number 143 fits into 1260 8 times, leaving a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 569959.188
The remainder is 116 after subtracting 1144 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

In conclusion, the division gives 569959.188 with a balance of 0.0116.
