We divide 19168539 by 640
We want to divide 19168539 by 640.

Going ahead to step 1:
1 divided by 640 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 640

Let's proceed to step 2:
640 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 640

Step 3:
If we divide 191 by 640, we get 0 and a remainder of 191.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 191 after subtracting 0 from 191.
Take the next digit (6) from the dividend and append it to 191, then repeat: 1916 / 640

Let's proceed to step 4:
If we divide 1916 by 640, we get 2 and a remainder of 636.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1280 from 1916 leaves us with 636.
Bring next digit (8) of the dividend behind the 636 and repeat the process: 6368 / 640

Moving on to step 5:
When dividing 6368 by 640, we get 9 with a remainder of 608.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 5760 from 6368, we get 608.
Bring next digit (5) of the dividend behind the 608 and repeat the process: 6085 / 640

Going ahead to step 6:
6085 divided by 640 is 9 with a remainder of 325.
Write down 9 as next digit of the result. 
Result so far: 299.0
If we subtract 5760 from 6085, we get 325.
Take the next digit (3) from the dividend and append it to 325, then repeat: 3253 / 640

Step 7:
The number 640 fits into 3253 5 times, leaving a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 2995.0
If we take 3200 away from 3253, we end up with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 640

Let's proceed to step 8:
640 goes into 539 0 times with a remainder of 539.
Use 0 as the next digit of our solution. 
Result so far: 29950.0
Subtract 0 from 539 to get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 9:
640 can be fit into 5390 8 times, resulting in a remainder of 270.
The number 8 becomes the next digit in our result. 
Result so far: 29950.8
If we take 5120 away from 5390, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
640 can be fit into 2700 4 times, resulting in a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 29950.84
If we take 2560 away from 2700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
640 can be fit into 1400 2 times, resulting in a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 29950.842
Subtracting 1280 from 1400 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
If we divide 1200 by 640, we get 1 and a remainder of 560.
The next digit of our result is 1. 
Result so far: 29950.8421
If we subtract 640 from 1200, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 13:
When dividing 5600 by 640, we get 8 with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 29950.84218
Deduct 5120 from 5600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
If we divide 4800 by 640, we get 7 and a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 29950.842187
If we subtract 4480 from 4800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
If we divide 3200 by 640, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29950.8421875
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:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29950.8421875
Subtracting 0 from 0 leaves us with 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 29950.8421875 and a remainder of 0.0.
