166109 ÷ 23 
Our goal is to divide 166109 by 23.

Going ahead to step 1:
23 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 23

Moving on to step 2:
16 divided by 23 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 23

Moving on to step 3:
23 goes into 166 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 161 from 166, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 23

Advancing to step 4:
23 goes into 51 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtract 46 from 51 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 23

Step 5:
When dividing 50 by 23, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 722.0
If we take 46 away from 50, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 23

Step 6:
49 divided by 23 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 7222.0
Subtracting 46 from 49 leaves us 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.

Going ahead to step 7:
If we divide 30 by 23, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 7222.1
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 7222.13
If we subtract 69 from 70, we 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.

On to step 9:
When dividing 10 by 23, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7222.13
If we take 0 away from 10, 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.

Advancing to step 10:
If we divide 100 by 23, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7222.1304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 23, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 7222.13043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 7222.130434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7222.1304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
190 divided by 23 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 7222.13043478
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 7222.13043478, with a leftover of 6e-09.
