35721 divided by 49 
We want to figure out the number of times 35721 can be divided by 49.

Advancing to step 1:
49 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 49

Moving on to step 2:
The number 49 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 49

On to step 3:
When dividing 357 by 49, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 343 from 357, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 49

On to step 4:
The number 49 fits into 142 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Deduct 98 from 142 and we're left with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 49

Going ahead to step 5:
The number 49 fits into 441 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 729.0
Deduct 441 from 441 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
The number 49 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 729.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 49 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 729.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 729.0 with a balance of 0.0.
