We look at the division of 639494 by 49 
Let's see how many times 49 fits into 639494.

Step 1:
6 divided by 49 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 49

On to step 2:
49 can be fit into 63 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 49 from 63, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 49

Let's proceed to step 3:
The number 49 fits into 149 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 147 from 149, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 49

Let's proceed to step 4:
49 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 130.0
Subtract 0 from 24 to get 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 49

Let's proceed to step 5:
The number 49 fits into 249 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 1305.0
If we take 245 away from 249, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 49

Let's proceed to step 6:
44 divided by 49 is 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 13050.0
If we take 0 away from 44, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
49 goes into 440 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 13050.8
The remainder is 48 after subtracting 392 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
480 divided by 49 is 9 with a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 13050.89
Deduct 441 from 480 and we're left 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.

Advancing to step 9:
49 can be fit into 390 7 times, resulting in a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 13050.897
If we take 343 away from 390, we end up 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 10:
49 goes into 470 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 13050.8979
Deduct 441 from 470 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 11:
The number 49 fits into 290 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 13050.89795
Subtracting 245 from 290 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 12:
When dividing 450 by 49, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 13050.897959
If we subtract 441 from 450, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
90 divided by 49 is 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 13050.8979591
Subtract 49 from 90 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 14:
When dividing 410 by 49, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 13050.89795918
Subtracting 392 from 410 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 13050.89795918 with a remainder of 1.8e-08.
