86031031 ÷ 180 
We want to figure out the number of times 86031031 can be divided by 180.

On to step 1:
180 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 180

On to step 2:
180 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 180

Let's proceed to step 3:
180 can be fit into 860 4 times, resulting in a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 720 from 860, we get 140.
Append the next digit (3) from the dividend to 140 and continue with: 1403 / 180

Step 4:
1403 divided by 180 is 7 with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 1260 away from 1403, we end up with 143.
Take the next digit (1) from the dividend and append it to 143, then repeat: 1431 / 180

Advancing to step 5:
If we divide 1431 by 180, we get 7 and a remainder of 171.
The next digit of our result is 7. 
Result so far: 477.0
Deduct 1260 from 1431 and we're left with 171.
Include the next digit (0) from the dividend after 171, then repeat: 1710 / 180

On to step 6:
180 can be fit into 1710 9 times, resulting in a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 4779.0
Subtract 1620 from 1710 to get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 180

Going ahead to step 7:
If we divide 903 by 180, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 47795.0
The remainder is 3 after subtracting 900 from 903.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 180

Going ahead to step 8:
180 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 477950.0
The remainder is 31 after subtracting 0 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
When dividing 310 by 180, we get 1 with a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 477950.1
If we take 180 away from 310, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
180 goes into 1300 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 477950.17
Deduct 1260 from 1300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 180, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 477950.172
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
400 divided by 180 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 477950.1722
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 477950.1722, with a leftover of 0.0004.
