Let's divide 639149 by 79
Our goal is to divide 639149 by 79.

Step 1:
If we divide 6 by 79, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 79

Going ahead to step 2:
When dividing 63 by 79, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 79

Advancing to step 3:
79 can be fit into 639 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 7 after subtracting 632 from 639.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 79

Advancing to step 4:
79 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtract 0 from 71 to get 71.
Include the next digit (4) from the dividend after 71, then repeat: 714 / 79

Advancing to step 5:
If we divide 714 by 79, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 809.0
Deduct 711 from 714 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 79

On to step 6:
79 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 8090.0
Subtracting 0 from 39 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.

Let's proceed to step 7:
79 goes into 390 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 8090.4
The remainder is 74 after subtracting 316 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
79 can be fit into 740 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 8090.49
Deduct 711 from 740 and we're left 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.

Going ahead to step 9:
When dividing 290 by 79, we get 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 8090.493
If we subtract 237 from 290, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 10:
When dividing 530 by 79, we get 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 8090.4936
Subtracting 474 from 530 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
79 can be fit into 560 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 8090.49367
Subtracting 553 from 560 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
79 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 8090.49367
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
When dividing 700 by 79, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 8090.4936708
Deduct 632 from 700 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
79 goes into 680 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8090.49367088
The remainder is 48 after subtracting 632 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 8090.49367088, with a leftover of 4.8e-08.
