We look at the division of 43393338 by 640 
We want to figure out the number of times 43393338 can be divided by 640.

Moving on to step 1:
The number 640 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 640

Let's proceed to step 2:
If we divide 43 by 640, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 640

Moving on to step 3:
When dividing 433 by 640, we get 0 with a remainder of 433.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 433 leaves us with 433.
Include the next digit (9) from the dividend after 433, then repeat: 4339 / 640

Going ahead to step 4:
If we divide 4339 by 640, we get 6 and a remainder of 499.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 3840 from 4339 leaves us with 499.
Take the next digit (3) from the dividend and append it to 499, then repeat: 4993 / 640

Moving on to step 5:
The number 640 fits into 4993 7 times, leaving a remainder of 513.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we subtract 4480 from 4993, we get 513.
Include the next digit (3) from the dividend after 513, then repeat: 5133 / 640

Advancing to step 6:
When dividing 5133 by 640, we get 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 678.0
Subtract 5120 from 5133 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 640

Step 7:
133 divided by 640 is 0 with a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 6780.0
Subtract 0 from 133 to get 133.
Take the next digit (8) from the dividend and append it to 133, then repeat: 1338 / 640

Let's proceed to step 8:
640 goes into 1338 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 67802.0
Deduct 1280 from 1338 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
When dividing 580 by 640, we get 0 with a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 67802.0
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 10:
640 can be fit into 5800 9 times, resulting in a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 67802.09
If we subtract 5760 from 5800, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 640, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 67802.09
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
640 can be fit into 4000 6 times, resulting in a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 67802.0906
Subtract 3840 from 4000 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.

Step 13:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 67802.09062
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.

Going ahead to step 14:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 67802.090625
If we subtract 3200 from 3200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67802.090625
If we take 0 away from 0, we end up 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.

On to step 16:
If we divide 0 by 640, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 67802.090625
If we subtract 0 from 0, we get 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 67802.090625 and a remainder of 0.0.
