Let's divide 18487 by 86
We want to divide 18487 by 86.

Step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 86

Advancing to step 2:
86 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 86

Step 3:
86 can be fit into 184 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 172 from 184 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 86

Advancing to step 4:
128 divided by 86 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 86 from 128 to get 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 86

Moving on to step 5:
The number 86 fits into 427 4 times, leaving a remainder of 83.
Use 4 as the next digit of our solution. 
Result so far: 214.0
Subtract 344 from 427 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 6:
86 goes into 830 9 times with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 214.9
If we subtract 774 from 830, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
86 goes into 560 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 214.96
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
When dividing 440 by 86, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 214.965
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 214.9651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
When dividing 140 by 86, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 214.96511
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 214.96511, with a leftover of 5.4e-05.
