We're dividing 643488 by 49 
Let's see how many times 49 fits into 643488.

Let's proceed to step 1:
49 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 49

Step 2:
49 can be fit into 64 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 15 after subtracting 49 from 64.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 49

Let's proceed to step 3:
The number 49 fits into 153 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 147 from 153 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 49

Let's proceed to step 4:
64 divided by 49 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtract 49 from 64 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 49

Going ahead to step 5:
49 goes into 158 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1313.0
The remainder is 11 after subtracting 147 from 158.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 49

Step 6:
The number 49 fits into 118 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 13132.0
Deduct 98 from 118 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 49 fits into 200 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 13132.4
If we subtract 196 from 200, we 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.

Moving on to step 8:
When dividing 40 by 49, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 13132.4
Subtract 0 from 40 to 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 9:
If we divide 400 by 49, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 13132.408
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
49 goes into 80 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 13132.4081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
49 goes into 310 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 13132.40816
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 49 fits into 160 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 13132.408163
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
49 can be fit into 130 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 13132.4081632
Subtract 98 from 130 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.

Moving on to step 14:
49 can be fit into 320 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 13132.40816326
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 13132.40816326 and a remainder of 2.6e-08.
