We look at the division of 559170 by 86 
We want to figure out the number of times 559170 can be divided by 86.

On to step 1:
86 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 86

Let's proceed to step 2:
When dividing 55 by 86, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 86

Step 3:
The number 86 fits into 559 6 times, leaving a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 516 away from 559, we end up with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 86

Going ahead to step 4:
86 can be fit into 431 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 430 from 431 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 86

On to step 5:
The number 86 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 650.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 86

Step 6:
The number 86 fits into 170 1 times, leaving a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 6501.0
Subtracting 86 from 170 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 7:
When dividing 840 by 86, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 6501.9
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 6501.97
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
When dividing 580 by 86, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 6501.976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 6501.9767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
If we divide 380 by 86, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 6501.97674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 6501.976744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 6501.976744, with a leftover of 1.6e-06.
