We look at the division of 531789 by 86 
Let's see how many times 86 fits into 531789.

Advancing to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 86

Let's proceed to step 2:
86 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 86

Going ahead to step 3:
If we divide 531 by 86, we get 6 and a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 15 after subtracting 516 from 531.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 86

Advancing to step 4:
The number 86 fits into 157 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 86 from 157, we get 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 86

Let's proceed to step 5:
718 divided by 86 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 618.0
Subtracting 688 from 718 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 86

Step 6:
The number 86 fits into 309 3 times, leaving a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 6183.0
The remainder is 51 after subtracting 258 from 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
When dividing 510 by 86, we get 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 6183.5
If we subtract 430 from 510, we 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.

Let's proceed to step 8:
86 goes into 800 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 6183.59
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 86, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 6183.593
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
20 divided by 86 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6183.593
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
If we divide 200 by 86, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6183.59302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
86 goes into 280 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 6183.593023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
If we divide 220 by 86, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 6183.5930232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
86 can be fit into 480 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 6183.59302325
If we subtract 430 from 480, we 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.

The final outcome is 6183.59302325, with a leftover of 5e-08.
