We divide 28109222 by 166
We're looking to find how many times 166 goes into 28109222.

Advancing to step 1:
The number 166 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 166

Let's proceed to step 2:
If we divide 28 by 166, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 166

On to step 3:
The number 166 fits into 281 1 times, leaving a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 166 from 281, we get 115.
Take the next digit (0) from the dividend and append it to 115, then repeat: 1150 / 166

Going ahead to step 4:
166 can be fit into 1150 6 times, resulting in a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 996 from 1150 and we're left with 154.
Fetch the next digit (9) from the dividend, attach it to 154 and continue: 1549 / 166

On to step 5:
166 can be fit into 1549 9 times, resulting in a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 169.0
Subtract 1494 from 1549 to get 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 166

Step 6:
If we divide 552 by 166, we get 3 and a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 1693.0
Subtract 498 from 552 to get 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 166

Step 7:
If we divide 542 by 166, we get 3 and a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 16933.0
If we take 498 away from 542, we end up with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 166

Let's proceed to step 8:
When dividing 442 by 166, we get 2 with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 169332.0
Deduct 332 from 442 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
If we divide 1100 by 166, we get 6 and a remainder of 104.
The next digit of our result is 6. 
Result so far: 169332.6
If we take 996 away from 1100, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
The number 166 fits into 1040 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 169332.66
Deduct 996 from 1040 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 169332.66, with a leftover of 0.044.
