641500 ÷ 79 
Let's see how many times 79 fits into 641500.

Advancing to step 1:
When dividing 6 by 79, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 79

Let's proceed to step 2:
If we divide 64 by 79, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 79

Step 3:
79 can be fit into 641 8 times, resulting in a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 9 after subtracting 632 from 641.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 79

Advancing to step 4:
The number 79 fits into 95 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 79 away from 95, we end up with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 79

Let's proceed to step 5:
If we divide 160 by 79, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
Deduct 158 from 160 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 79

On to step 6:
79 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8120.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
200 divided by 79 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 8120.2
Deduct 158 from 200 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
79 can be fit into 420 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8120.25
Subtract 395 from 420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 79 fits into 250 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 8120.253
Deduct 237 from 250 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
If we divide 130 by 79, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 8120.2531
Subtract 79 from 130 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
79 goes into 510 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 8120.25316
Subtract 474 from 510 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
When dividing 360 by 79, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 8120.253164
Subtract 316 from 360 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
440 divided by 79 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 8120.2531645
Subtract 395 from 440 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
The number 79 fits into 450 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8120.25316455
If we subtract 395 from 450, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 8120.25316455 with a remainder of 5.5e-08.
