We're dividing 20639086 by 738 
We want to divide 20639086 by 738.

Let's proceed to step 1:
When dividing 2 by 738, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 738

Let's proceed to step 2:
20 divided by 738 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 738

Moving on to step 3:
When dividing 206 by 738, we get 0 with a remainder of 206.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 206 and we're left with 206.
Fetch the next digit (3) from the dividend, attach it to 206 and continue: 2063 / 738

Advancing to step 4:
738 goes into 2063 2 times with a remainder of 587.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 587 after subtracting 1476 from 2063.
Append the next digit (9) from the dividend to 587 and continue with: 5879 / 738

Moving on to step 5:
When dividing 5879 by 738, we get 7 with a remainder of 713.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 5166 away from 5879, we end up with 713.
Take the next digit (0) from the dividend and append it to 713, then repeat: 7130 / 738

Going ahead to step 6:
738 can be fit into 7130 9 times, resulting in a remainder of 488.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
Subtract 6642 from 7130 to get 488.
Take the next digit (8) from the dividend and append it to 488, then repeat: 4888 / 738

Moving on to step 7:
If we divide 4888 by 738, we get 6 and a remainder of 460.
Write down 6 as next digit of the result. 
Result so far: 2796.0
If we subtract 4428 from 4888, we get 460.
Fetch the next digit (6) from the dividend, attach it to 460 and continue: 4606 / 738

Moving on to step 8:
If we divide 4606 by 738, we get 6 and a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 27966.0
If we subtract 4428 from 4606, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 9:
If we divide 1780 by 738, we get 2 and a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 27966.2
Subtract 1476 from 1780 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 10:
738 goes into 3040 4 times with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 27966.24
Deduct 2952 from 3040 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
738 can be fit into 880 1 times, resulting in a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 27966.241
Subtracting 738 from 880 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 12:
If we divide 1420 by 738, we get 1 and a remainder of 682.
Record the quotient 1 as the next digit in the result. 
Result so far: 27966.2411
If we take 738 away from 1420, we end up with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

The final outcome is 27966.2411, with a leftover of 0.00682.
