We're dividing 645054 by 79 
We want to figure out the number of times 645054 can be divided by 79.

On to step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 79

Moving on to step 2:
When dividing 64 by 79, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 79

On to step 3:
79 can be fit into 645 8 times, resulting in a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 632 from 645, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 79

On to step 4:
The number 79 fits into 130 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Deduct 79 from 130 and we're left with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 79

Advancing to step 5:
The number 79 fits into 515 6 times, leaving a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 816.0
Subtracting 474 from 515 leaves us with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 79

Moving on to step 6:
The number 79 fits into 414 5 times, leaving a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 8165.0
Subtract 395 from 414 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
The number 79 fits into 190 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 8165.2
Subtract 158 from 190 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
79 goes into 320 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 8165.24
Subtract 316 from 320 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 79 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8165.24
If we subtract 0 from 40, 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 10:
The number 79 fits into 400 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 8165.2405
If we take 395 away from 400, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
79 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8165.2405
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
If we divide 500 by 79, we get 6 and a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 8165.240506
The remainder is 26 after subtracting 474 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
The number 79 fits into 260 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 8165.2405063
Subtract 237 from 260 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
79 goes into 230 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 8165.24050632
Subtracting 158 from 230 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 8165.24050632, and the remainder is 7.2e-08.
