We're dividing 86172168 by 559 
We want to divide 86172168 by 559.

Step 1:
If we divide 8 by 559, we get 0 and 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 559

On to step 2:
When dividing 86 by 559, we get 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.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 559

On to step 3:
861 divided by 559 is 1 with a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 559 from 861 and we're left with 302.
Grab the next digit (7) from the dividend, add it to 302, then carry on: 3027 / 559

On to step 4:
If we divide 3027 by 559, we get 5 and a remainder of 232.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 2795 from 3027 leaves us with 232.
Fetch the next digit (2) from the dividend, attach it to 232 and continue: 2322 / 559

Step 5:
When dividing 2322 by 559, we get 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 154.0
If we take 2236 away from 2322, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 559

Let's proceed to step 6:
861 divided by 559 is 1 with a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 1541.0
If we take 559 away from 861, we end up with 302.
Bring next digit (6) of the dividend behind the 302 and repeat the process: 3026 / 559

Going ahead to step 7:
If we divide 3026 by 559, we get 5 and a remainder of 231.
The number 5 becomes the next digit in our result. 
Result so far: 15415.0
If we take 2795 away from 3026, we end up with 231.
Fetch the next digit (8) from the dividend, attach it to 231 and continue: 2318 / 559

On to step 8:
If we divide 2318 by 559, we get 4 and a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 154154.0
The remainder is 82 after subtracting 2236 from 2318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
559 can be fit into 820 1 times, resulting in a remainder of 261.
Record the quotient 1 as the next digit in the result. 
Result so far: 154154.1
The remainder is 261 after subtracting 559 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 10:
559 can be fit into 2610 4 times, resulting in a remainder of 374.
Record the quotient 4 as the next digit in the result. 
Result so far: 154154.14
Subtracting 2236 from 2610 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
559 goes into 3740 6 times with a remainder of 386.
Write down 6 as next digit of the result. 
Result so far: 154154.146
If we take 3354 away from 3740, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 12:
559 goes into 3860 6 times with a remainder of 506.
Put 6 as the next digit of the answer. 
Result so far: 154154.1466
Deduct 3354 from 3860 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

In conclusion, the division gives 154154.1466 with a balance of 0.00506.
