23734448 ÷ 640 
We're looking to find how many times 640 goes into 23734448.

Step 1:
2 divided by 640 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 640

Moving on to step 2:
If we divide 23 by 640, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 640

On to step 3:
237 divided by 640 is 0 with a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 237 to get 237.
Include the next digit (3) from the dividend after 237, then repeat: 2373 / 640

Advancing to step 4:
The number 640 fits into 2373 3 times, leaving a remainder of 453.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1920 from 2373 and we're left with 453.
Fetch the next digit (4) from the dividend, attach it to 453 and continue: 4534 / 640

Let's proceed to step 5:
640 can be fit into 4534 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 4480 from 4534 and we're left with 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 640

Moving on to step 6:
If we divide 544 by 640, we get 0 and a remainder of 544.
Record the quotient 0 as the next digit in the result. 
Result so far: 370.0
Subtract 0 from 544 to get 544.
Append the next digit (4) from the dividend to 544 and continue with: 5444 / 640

Advancing to step 7:
If we divide 5444 by 640, we get 8 and a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 3708.0
If we subtract 5120 from 5444, we get 324.
Bring next digit (8) of the dividend behind the 324 and repeat the process: 3248 / 640

On to step 8:
The number 640 fits into 3248 5 times, leaving a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 37085.0
Deduct 3200 from 3248 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
640 goes into 480 0 times with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 37085.0
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 37085.07
The remainder is 320 after subtracting 4480 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 11:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 37085.075
Deduct 3200 from 3200 and we're left 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.

Step 12:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37085.075
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.

Let's proceed to step 13:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37085.075
Subtract 0 from 0 to 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.

Our division results in 37085.075 with a remaining 0.0.
