We're dividing 86508611 by 611 
We want to divide 86508611 by 611.

Moving on to step 1:
611 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 611

Step 2:
86 divided by 611 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 611

Let's proceed to step 3:
When dividing 865 by 611, we get 1 with a remainder of 254.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 254 after subtracting 611 from 865.
Include the next digit (0) from the dividend after 254, then repeat: 2540 / 611

Moving on to step 4:
611 goes into 2540 4 times with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 96 after subtracting 2444 from 2540.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 611

Let's proceed to step 5:
968 divided by 611 is 1 with a remainder of 357.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Deduct 611 from 968 and we're left with 357.
Bring next digit (6) of the dividend behind the 357 and repeat the process: 3576 / 611

Advancing to step 6:
611 goes into 3576 5 times with a remainder of 521.
The number 5 becomes the next digit in our result. 
Result so far: 1415.0
Subtract 3055 from 3576 to get 521.
Fetch the next digit (1) from the dividend, attach it to 521 and continue: 5211 / 611

Going ahead to step 7:
5211 divided by 611 is 8 with a remainder of 323.
The number 8 becomes the next digit in our result. 
Result so far: 14158.0
Subtract 4888 from 5211 to get 323.
Append the next digit (1) from the dividend to 323 and continue with: 3231 / 611

Let's proceed to step 8:
611 can be fit into 3231 5 times, resulting in a remainder of 176.
Use 5 as the next digit of our solution. 
Result so far: 141585.0
The remainder is 176 after subtracting 3055 from 3231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
When dividing 1760 by 611, we get 2 with a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 141585.2
If we subtract 1222 from 1760, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Let's proceed to step 10:
611 can be fit into 5380 8 times, resulting in a remainder of 492.
The next digit of our result is 8. 
Result so far: 141585.28
Deduct 4888 from 5380 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 11:
If we divide 4920 by 611, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 141585.288
If we take 4888 away from 4920, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 141585.288, with a leftover of 0.0032.
