Let's divide 172145 by 85
Let's see how many times 85 fits into 172145.

Going ahead to step 1:
The number 85 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 85

Advancing to step 2:
85 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 85

Going ahead to step 3:
When dividing 172 by 85, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 170 away from 172, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 85

Step 4:
When dividing 21 by 85, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 21 to get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 85

Advancing to step 5:
214 divided by 85 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Subtract 170 from 214 to get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 85

Advancing to step 6:
If we divide 445 by 85, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 2025.0
The remainder is 20 after subtracting 425 from 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
200 divided by 85 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2025.2
If we take 170 away from 200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
85 goes into 300 3 times with a remainder of 45.
The next digit of our result is 3. 
Result so far: 2025.23
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
When dividing 450 by 85, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2025.235
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 2025.2352
If we subtract 170 from 250, 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.

On to step 11:
85 goes into 800 9 times with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 2025.23529
If we subtract 765 from 800, we get 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 12:
When dividing 350 by 85, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 2025.235294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 85, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 2025.2352941
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 2025.23529411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 2025.23529411, and the remainder is 6.5e-08.
