Let's divide 86855920 by 143
Our goal is to divide 86855920 by 143.

Let's proceed to step 1:
8 divided by 143 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 143

Let's proceed to step 2:
86 divided by 143 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 143

Moving on to step 3:
868 divided by 143 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 858 from 868 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 143

Let's proceed to step 4:
When dividing 105 by 143, we get 0 with a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 105, we end up with 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 143

Advancing to step 5:
1055 divided by 143 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 607.0
If we subtract 1001 from 1055, we get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 143

Moving on to step 6:
If we divide 549 by 143, we get 3 and a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 6073.0
Subtract 429 from 549 to get 120.
Fetch the next digit (2) from the dividend, attach it to 120 and continue: 1202 / 143

Going ahead to step 7:
1202 divided by 143 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 60738.0
Subtract 1144 from 1202 to get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 143

Let's proceed to step 8:
143 goes into 580 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 607384.0
Subtracting 572 from 580 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
143 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 607384.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
The number 143 fits into 800 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 607384.05
Subtracting 715 from 800 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 11:
143 can be fit into 850 5 times, resulting in a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 607384.055
Subtract 715 from 850 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

In conclusion, the division gives 607384.055 with a balance of 0.0135.
