621616 divided by 49 
We want to divide 621616 by 49.

Moving on to step 1:
6 divided by 49 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 49

Moving on to step 2:
49 goes into 62 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 49 away from 62, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 49

Going ahead to step 3:
The number 49 fits into 131 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 98 from 131 to get 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 49

Advancing to step 4:
336 divided by 49 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 294 from 336 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 49

Step 5:
If we divide 421 by 49, we get 8 and a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 1268.0
If we take 392 away from 421, we end up with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 49

Advancing to step 6:
If we divide 296 by 49, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 12686.0
If we subtract 294 from 296, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 49 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12686.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 49, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 12686.04
If we take 196 away from 200, we end up with 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 9:
49 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12686.04
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
49 goes into 400 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 12686.0408
Subtract 392 from 400 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
80 divided by 49 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 12686.04081
Subtracting 49 from 80 leaves us 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 12:
When dividing 310 by 49, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 12686.040816
Subtract 294 from 310 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
49 goes into 160 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 12686.0408163
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
If we divide 130 by 49, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12686.04081632
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.

The final outcome is 12686.04081632, with a leftover of 3.2e-08.
