Let's divide 172035 by 86
We want to figure out the number of times 172035 can be divided by 86.

Step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 86

Going ahead to step 2:
If we divide 17 by 86, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 86

Going ahead to step 3:
The number 86 fits into 172 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 172 from 172, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 86

On to step 4:
86 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 86

Advancing to step 5:
If we divide 3 by 86, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 86

On to step 6:
If we divide 35 by 86, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 2000.0
Subtracting 0 from 35 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
86 goes into 350 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 2000.4
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 86 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2000.4
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
86 goes into 600 6 times with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 2000.406
If we take 516 away from 600, we end up 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.

Going ahead to step 10:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 2000.4069
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.

Let's proceed to step 11:
If we divide 660 by 86, we get 7 and a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 2000.40697
Deduct 602 from 660 and we're left 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.

On to step 12:
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: 2000.406976
Subtracting 516 from 580 leaves us 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.

Let's proceed to step 13:
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: 2000.4069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
86 goes into 380 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 2000.40697674
Subtracting 344 from 380 leaves us 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.

In conclusion, the division gives 2000.40697674 with a balance of 3.6e-08.
