We look at the division of 19304397 by 640 
We're looking to find how many times 640 goes into 19304397.

On to step 1:
When dividing 1 by 640, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 640

Advancing to step 2:
640 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 640

On to step 3:
The number 640 fits into 193 0 times, leaving a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 193, we get 193.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 640

Let's proceed to step 4:
The number 640 fits into 1930 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1920 from 1930 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 640

Advancing to step 5:
The number 640 fits into 104 0 times, leaving a remainder of 104.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 104 leaves us with 104.
Take the next digit (3) from the dividend and append it to 104, then repeat: 1043 / 640

Step 6:
1043 divided by 640 is 1 with a remainder of 403.
Use 1 as the next digit of our solution. 
Result so far: 301.0
The remainder is 403 after subtracting 640 from 1043.
Grab the next digit (9) from the dividend, add it to 403, then carry on: 4039 / 640

On to step 7:
640 goes into 4039 6 times with a remainder of 199.
Put 6 as the next digit of the answer. 
Result so far: 3016.0
Subtract 3840 from 4039 to get 199.
Bring next digit (7) of the dividend behind the 199 and repeat the process: 1997 / 640

Step 8:
640 goes into 1997 3 times with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 30163.0
If we take 1920 away from 1997, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
The number 640 fits into 770 1 times, leaving a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 30163.1
Deduct 640 from 770 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
When dividing 1300 by 640, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 30163.12
If we take 1280 away from 1300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
640 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 30163.12
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.

Advancing to step 12:
640 goes into 2000 3 times with a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 30163.1203
If we subtract 1920 from 2000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
If we divide 800 by 640, we get 1 and a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 30163.12031
Subtract 640 from 800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
When dividing 1600 by 640, we get 2 with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 30163.120312
The remainder is 320 after subtracting 1280 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
When dividing 3200 by 640, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 30163.1203125
The remainder is 0 after subtracting 3200 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30163.1203125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 30163.1203125 and a remainder of 0.0.
