We look at the division of 167666 by 85 
We want to figure out the number of times 167666 can be divided by 85.

Step 1:
When dividing 1 by 85, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 85

On to step 2:
When dividing 16 by 85, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 85

On to step 3:
85 can be fit into 167 1 times, resulting in a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 85 away from 167, we end up with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 85

Let's proceed to step 4:
826 divided by 85 is 9 with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 765 from 826 leaves us with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 85

Step 5:
When dividing 616 by 85, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 197.0
Subtract 595 from 616 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 85

On to step 6:
The number 85 fits into 216 2 times, leaving a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 1972.0
Subtracting 170 from 216 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
When dividing 460 by 85, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1972.5
If we subtract 425 from 460, 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.

On to step 8:
85 goes into 350 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 1972.54
Subtracting 340 from 350 leaves us 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.

Moving on to step 9:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1972.541
Subtracting 85 from 100 leaves us 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.

Advancing to step 10:
When dividing 150 by 85, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1972.5411
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 1972.5411 and a remainder of 0.00065.
