We're dividing 213130 by 86 
We want to figure out the number of times 213130 can be divided by 86.

Advancing to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 86

Let's proceed to step 2:
The number 86 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 86

Let's proceed to step 3:
86 goes into 213 2 times with a remainder of 41.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 172 from 213 and we're left with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 86

Step 4:
When dividing 411 by 86, we get 4 with a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 67 after subtracting 344 from 411.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 86

On to step 5:
When dividing 673 by 86, we get 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 247.0
If we subtract 602 from 673, we get 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 86

Advancing to step 6:
The number 86 fits into 710 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 2478.0
The remainder is 22 after subtracting 688 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
86 goes into 220 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 2478.2
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
480 divided by 86 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2478.25
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 86 fits into 500 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 2478.255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 2478.255, with a leftover of 0.007.
