Let's divide 20781666 by 156
We want to divide 20781666 by 156.

Moving on to step 1:
2 divided by 156 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 156

Let's proceed to step 2:
If we divide 20 by 156, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 156

On to step 3:
156 can be fit into 207 1 times, resulting in a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 156 from 207 and we're left with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 156

Step 4:
If we divide 518 by 156, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 50 after subtracting 468 from 518.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 156

Step 5:
501 divided by 156 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we subtract 468 from 501, we get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 156

Advancing to step 6:
The number 156 fits into 336 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1332.0
If we take 312 away from 336, we end up with 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 156

Advancing to step 7:
156 can be fit into 246 1 times, resulting in a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 13321.0
Subtract 156 from 246 to get 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 156

On to step 8:
When dividing 906 by 156, we get 5 with a remainder of 126.
The next digit of our result is 5. 
Result so far: 133215.0
Deduct 780 from 906 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 9:
The number 156 fits into 1260 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 133215.8
If we take 1248 away from 1260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
156 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 133215.8
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
When dividing 1200 by 156, we get 7 with a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 133215.807
If we take 1092 away from 1200, we end up with 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 12:
The number 156 fits into 1080 6 times, leaving a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 133215.8076
Subtracting 936 from 1080 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
1440 divided by 156 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 133215.80769
Subtracting 1404 from 1440 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
If we divide 360 by 156, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 133215.807692
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 15:
156 can be fit into 480 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 133215.8076923
If we subtract 468 from 480, we 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 16:
The number 156 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 133215.8076923
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 133215.8076923, and the remainder is 1.2e-07.
