Let's divide 163503 by 86
We want to figure out the number of times 163503 can be divided by 86.

Advancing to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 86

Moving on to step 2:
86 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 86

Let's proceed to step 3:
86 goes into 163 1 times with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 86 from 163 and we're left with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 86

Advancing to step 4:
86 can be fit into 775 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 774 away from 775, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 86

Going ahead to step 5:
The number 86 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 190.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 86

Going ahead to step 6:
86 goes into 103 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1901.0
Subtracting 86 from 103 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
If we divide 170 by 86, we get 1 and a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1901.1
Subtract 86 from 170 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
840 divided by 86 is 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 1901.19
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
86 goes into 660 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 1901.197
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
580 divided by 86 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1901.1976
The remainder is 64 after subtracting 516 from 580.
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 11:
86 goes into 640 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 1901.19767
If we subtract 602 from 640, we get 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 12:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1901.197674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
If we divide 360 by 86, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1901.1976744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 1901.1976744 with a balance of 1.6e-07.
