12439662 ÷ 79 
We want to divide 12439662 by 79.

Step 1:
If we divide 1 by 79, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 79

Step 2:
79 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 79

Going ahead to step 3:
124 divided by 79 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
If we take 79 away from 124, we end up with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 79

Moving on to step 4:
453 divided by 79 is 5 with a remainder of 58.
The next digit of our result is 5. 
Result so far: 15.0
If we take 395 away from 453, we end up with 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 79

Going ahead to step 5:
When dividing 589 by 79, we get 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
If we take 553 away from 589, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 79

Step 6:
79 goes into 366 4 times with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 1574.0
Subtract 316 from 366 to get 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 79

Let's proceed to step 7:
506 divided by 79 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 15746.0
Subtract 474 from 506 to get 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 79

On to step 8:
322 divided by 79 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 157464.0
Deduct 316 from 322 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
If we divide 60 by 79, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 157464.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
The number 79 fits into 600 7 times, leaving a remainder of 47.
The next digit of our result is 7. 
Result so far: 157464.07
Deduct 553 from 600 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
79 goes into 470 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 157464.075
Deduct 395 from 470 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
The number 79 fits into 750 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 157464.0759
Subtracting 711 from 750 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
The number 79 fits into 390 4 times, leaving a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 157464.07594
If we subtract 316 from 390, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
79 can be fit into 740 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 157464.075949
If we take 711 away from 740, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 15:
The number 79 fits into 290 3 times, leaving a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 157464.0759493
Deduct 237 from 290 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 16:
The number 79 fits into 530 6 times, leaving a remainder of 56.
The next digit of our result is 6. 
Result so far: 157464.07594936
If we subtract 474 from 530, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 157464.07594936, and the remainder is 5.6e-08.
