82346172 ÷ 640 
Let's see how many times 640 fits into 82346172.

Step 1:
When dividing 8 by 640, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 640

Moving on to step 2:
The number 640 fits into 82 0 times, leaving a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Bring next digit (3) of the dividend behind the 82 and repeat the process: 823 / 640

Moving on to step 3:
If we divide 823 by 640, we get 1 and a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 183 after subtracting 640 from 823.
Include the next digit (4) from the dividend after 183, then repeat: 1834 / 640

Going ahead to step 4:
640 can be fit into 1834 2 times, resulting in a remainder of 554.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1280 from 1834 leaves us with 554.
Fetch the next digit (6) from the dividend, attach it to 554 and continue: 5546 / 640

Moving on to step 5:
640 goes into 5546 8 times with a remainder of 426.
Put 8 as the next digit of the answer. 
Result so far: 128.0
The remainder is 426 after subtracting 5120 from 5546.
Append the next digit (1) from the dividend to 426 and continue with: 4261 / 640

Moving on to step 6:
640 goes into 4261 6 times with a remainder of 421.
Write down 6 as next digit of the result. 
Result so far: 1286.0
Subtracting 3840 from 4261 leaves us with 421.
Take the next digit (7) from the dividend and append it to 421, then repeat: 4217 / 640

Going ahead to step 7:
4217 divided by 640 is 6 with a remainder of 377.
The number 6 becomes the next digit in our result. 
Result so far: 12866.0
Deduct 3840 from 4217 and we're left with 377.
Fetch the next digit (2) from the dividend, attach it to 377 and continue: 3772 / 640

Let's proceed to step 8:
640 goes into 3772 5 times with a remainder of 572.
The number 5 becomes the next digit in our result. 
Result so far: 128665.0
If we subtract 3200 from 3772, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 9:
640 can be fit into 5720 8 times, resulting in a remainder of 600.
Record the quotient 8 as the next digit in the result. 
Result so far: 128665.8
Subtracting 5120 from 5720 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 10:
640 goes into 6000 9 times with a remainder of 240.
Write down 9 as next digit of the result. 
Result so far: 128665.89
Deduct 5760 from 6000 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
640 can be fit into 2400 3 times, resulting in a remainder of 480.
Put 3 as the next digit of the answer. 
Result so far: 128665.893
Subtract 1920 from 2400 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.

Let's proceed to step 12:
640 goes into 4800 7 times with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 128665.8937
Deduct 4480 from 4800 and we're left with 320.
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 13:
3200 divided by 640 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 128665.89375
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.

Moving on to step 14:
When dividing 0 by 640, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 128665.89375
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.

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: 128665.89375
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.

Our division results in 128665.89375 with a remaining 0.0.
