We divide 166975 by 13
We want to figure out the number of times 166975 can be divided by 13.

Moving on to step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 13

On to step 2:
If we divide 16 by 13, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 13 from 16, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 13

Moving on to step 3:
13 goes into 36 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 26 from 36 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 13

Going ahead to step 4:
If we divide 109 by 13, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 104 from 109 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 13

Step 5:
When dividing 57 by 13, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 1284.0
If we take 52 away from 57, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 13

Let's proceed to step 6:
If we divide 55 by 13, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 12844.0
If we take 52 away from 55, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 12844.2
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 12844.23
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12844.23
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 12844.2307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 13, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12844.23076
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 13 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 12844.230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 13 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12844.2307692
Deduct 26 from 30 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
When dividing 40 by 13, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 12844.23076923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 12844.23076923 and a remainder of 1e-09.
