72184788 divided by 640 
We want to figure out the number of times 72184788 can be divided by 640.

On to step 1:
640 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 640

Moving on to step 2:
When dividing 72 by 640, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 640

On to step 3:
640 goes into 721 1 times with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 81 after subtracting 640 from 721.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 640

On to step 4:
When dividing 818 by 640, we get 1 with a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 640 from 818 and we're left with 178.
Take the next digit (4) from the dividend and append it to 178, then repeat: 1784 / 640

Going ahead to step 5:
The number 640 fits into 1784 2 times, leaving a remainder of 504.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Deduct 1280 from 1784 and we're left with 504.
Fetch the next digit (7) from the dividend, attach it to 504 and continue: 5047 / 640

On to step 6:
640 goes into 5047 7 times with a remainder of 567.
Put 7 as the next digit of the answer. 
Result so far: 1127.0
Subtracting 4480 from 5047 leaves us with 567.
Include the next digit (8) from the dividend after 567, then repeat: 5678 / 640

Moving on to step 7:
When dividing 5678 by 640, we get 8 with a remainder of 558.
The number 8 becomes the next digit in our result. 
Result so far: 11278.0
Deduct 5120 from 5678 and we're left with 558.
Take the next digit (8) from the dividend and append it to 558, then repeat: 5588 / 640

Going ahead to step 8:
640 goes into 5588 8 times with a remainder of 468.
Record the quotient 8 as the next digit in the result. 
Result so far: 112788.0
The remainder is 468 after subtracting 5120 from 5588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 9:
640 goes into 4680 7 times with a remainder of 200.
Record the quotient 7 as the next digit in the result. 
Result so far: 112788.7
If we subtract 4480 from 4680, we 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 10:
640 goes into 2000 3 times with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 112788.73
Deduct 1920 from 2000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
640 goes into 800 1 times with a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 112788.731
If we subtract 640 from 800, we 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 12:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
The next digit of our result is 2. 
Result so far: 112788.7312
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.

Let's proceed to step 13:
640 goes into 3200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 112788.73125
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 14:
If we divide 0 by 640, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 112788.73125
Deduct 0 from 0 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 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 112788.73125
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.

Our division results in 112788.73125 with a remaining 0.0.
