512112 ÷ 79 
We want to figure out the number of times 512112 can be divided by 79.

On to step 1:
If we divide 5 by 79, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 79

Let's proceed to step 2:
The number 79 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 79

Let's proceed to step 3:
79 can be fit into 512 6 times, resulting in a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 474 from 512 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 79

Going ahead to step 4:
79 goes into 381 4 times with a remainder of 65.
The next digit of our result is 4. 
Result so far: 64.0
If we take 316 away from 381, we end up with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 79

Advancing to step 5:
79 can be fit into 651 8 times, resulting in a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 648.0
If we take 632 away from 651, we end up with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 79

Let's proceed to step 6:
The number 79 fits into 192 2 times, leaving a remainder of 34.
The next digit of our result is 2. 
Result so far: 6482.0
Subtracting 158 from 192 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
If we divide 340 by 79, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 6482.4
Subtracting 316 from 340 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
79 can be fit into 240 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 6482.43
Deduct 237 from 240 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 79 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 6482.43
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 79 fits into 300 3 times, leaving a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 6482.4303
If we take 237 away from 300, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 11:
79 goes into 630 7 times with a remainder of 77.
The next digit of our result is 7. 
Result so far: 6482.43037
If we subtract 553 from 630, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 12:
79 goes into 770 9 times with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 6482.430379
If we take 711 away from 770, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 13:
79 goes into 590 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 6482.4303797
Deduct 553 from 590 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
The number 79 fits into 370 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 6482.43037974
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 6482.43037974 with a remaining 5.4e-08.
