Let's divide 38909210 by 644
We want to divide 38909210 by 644.

Moving on to step 1:
3 divided by 644 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 644

Let's proceed to step 2:
38 divided by 644 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 644

Step 3:
644 can be fit into 389 0 times, resulting in a remainder of 389.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 389 leaves us with 389.
Take the next digit (0) from the dividend and append it to 389, then repeat: 3890 / 644

Going ahead to step 4:
The number 644 fits into 3890 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 3864 away from 3890, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 644

Let's proceed to step 5:
The number 644 fits into 269 0 times, leaving a remainder of 269.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 269 to get 269.
Include the next digit (2) from the dividend after 269, then repeat: 2692 / 644

Step 6:
If we divide 2692 by 644, we get 4 and a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 604.0
If we subtract 2576 from 2692, we get 116.
Append the next digit (1) from the dividend to 116 and continue with: 1161 / 644

Step 7:
The number 644 fits into 1161 1 times, leaving a remainder of 517.
Record the quotient 1 as the next digit in the result. 
Result so far: 6041.0
Deduct 644 from 1161 and we're left with 517.
Take the next digit (0) from the dividend and append it to 517, then repeat: 5170 / 644

Step 8:
The number 644 fits into 5170 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 60418.0
Deduct 5152 from 5170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
644 goes into 180 0 times with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 60418.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
644 goes into 1800 2 times with a remainder of 512.
The next digit of our result is 2. 
Result so far: 60418.02
If we take 1288 away from 1800, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 11:
The number 644 fits into 5120 7 times, leaving a remainder of 612.
Write down 7 as next digit of the result. 
Result so far: 60418.027
The remainder is 612 after subtracting 4508 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 12:
644 goes into 6120 9 times with a remainder of 324.
Put 9 as the next digit of the answer. 
Result so far: 60418.0279
Subtract 5796 from 6120 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 13:
3240 divided by 644 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 60418.02795
If we subtract 3220 from 3240, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
644 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 60418.02795
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 15:
When dividing 2000 by 644, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 60418.0279503
If we subtract 1932 from 2000, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 16:
If we divide 680 by 644, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 60418.02795031
Subtract 644 from 680 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 60418.02795031 with a balance of 3.6e-08.
