We look at the division of 20724706 by 166 
Our goal is to divide 20724706 by 166.

Step 1:
166 goes into 2 0 times with 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.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 166

Advancing to step 2:
When dividing 20 by 166, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 166

Step 3:
When dividing 207 by 166, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 166 from 207, we get 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 166

On to step 4:
When dividing 412 by 166, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 332 from 412 leaves us with 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 166

Advancing to step 5:
166 goes into 804 4 times with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 664 away from 804, we end up with 140.
Fetch the next digit (7) from the dividend, attach it to 140 and continue: 1407 / 166

Step 6:
166 goes into 1407 8 times with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 1248.0
If we subtract 1328 from 1407, we get 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 166

Step 7:
166 goes into 790 4 times with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 12484.0
Subtracting 664 from 790 leaves us with 126.
Take the next digit (6) from the dividend and append it to 126, then repeat: 1266 / 166

Moving on to step 8:
166 can be fit into 1266 7 times, resulting in a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 124847.0
If we subtract 1162 from 1266, we get 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 9:
When dividing 1040 by 166, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 124847.6
Subtracting 996 from 1040 leaves us 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.

Advancing to step 10:
When dividing 440 by 166, we get 2 with a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 124847.62
If we subtract 332 from 440, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
If we divide 1080 by 166, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 124847.626
If we take 996 away from 1080, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
166 goes into 840 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 124847.6265
The remainder is 10 after subtracting 830 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
166 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 124847.6265
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
If we divide 1000 by 166, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 124847.626506
If we take 996 away from 1000, we end up 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 15:
166 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 124847.626506
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
400 divided by 166 is 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 124847.62650602
Subtracting 332 from 400 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Our division results in 124847.62650602 with a remaining 6.8e-08.
