Let's divide 189172 by 85
We're looking to find how many times 85 goes into 189172.

Advancing to step 1:
85 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 85

Advancing to step 2:
85 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 85

Moving on to step 3:
If we divide 189 by 85, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 170 from 189 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 85

Advancing to step 4:
When dividing 191 by 85, we get 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 170 from 191 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 85

Moving on to step 5:
When dividing 217 by 85, we get 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 222.0
Deduct 170 from 217 and we're left with 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 85

Going ahead to step 6:
85 goes into 472 5 times with a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 2225.0
Subtracting 425 from 472 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
The number 85 fits into 470 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2225.5
If we take 425 away from 470, we end up 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.

Step 8:
85 can be fit into 450 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2225.55
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 2225.55, with a leftover of 0.025.
