We're dividing 20778 by 644 
Our goal is to divide 20778 by 644.

Moving on to step 1:
If we divide 2 by 644, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 644

On to step 2:
644 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 644

Step 3:
644 goes into 207 0 times with a remainder of 207.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 207 and we're left with 207.
Take the next digit (7) from the dividend and append it to 207, then repeat: 2077 / 644

Step 4:
644 can be fit into 2077 3 times, resulting in a remainder of 145.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 145 after subtracting 1932 from 2077.
Take the next digit (8) from the dividend and append it to 145, then repeat: 1458 / 644

Advancing to step 5:
1458 divided by 644 is 2 with a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
The remainder is 170 after subtracting 1288 from 1458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 6:
If we divide 1700 by 644, we get 2 and a remainder of 412.
Use 2 as the next digit of our solution. 
Result so far: 32.2
The remainder is 412 after subtracting 1288 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 7:
The number 644 fits into 4120 6 times, leaving a remainder of 256.
The next digit of our result is 6. 
Result so far: 32.26
Subtracting 3864 from 4120 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 8:
The number 644 fits into 2560 3 times, leaving a remainder of 628.
Use 3 as the next digit of our solution. 
Result so far: 32.263
Subtracting 1932 from 2560 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 9:
6280 divided by 644 is 9 with a remainder of 484.
Record the quotient 9 as the next digit in the result. 
Result so far: 32.2639
Subtracting 5796 from 6280 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 10:
The number 644 fits into 4840 7 times, leaving a remainder of 332.
Record the quotient 7 as the next digit in the result. 
Result so far: 32.26397
Deduct 4508 from 4840 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 11:
When dividing 3320 by 644, we get 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 32.263975
Deduct 3220 from 3320 and we're left with 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 12:
1000 divided by 644 is 1 with a remainder of 356.
Record the quotient 1 as the next digit in the result. 
Result so far: 32.2639751
Subtract 644 from 1000 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 13:
3560 divided by 644 is 5 with a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 32.26397515
If we take 3220 away from 3560, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 32.26397515, with a leftover of 3.4e-07.
