We divide 210721 by 61
We want to figure out the number of times 210721 can be divided by 61.

Moving on to step 1:
61 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 61

Step 2:
21 divided by 61 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 61

Moving on to step 3:
61 can be fit into 210 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 183 from 210 and we're left with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 61

Moving on to step 4:
The number 61 fits into 277 4 times, leaving a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtracting 244 from 277 leaves us with 33.
Include the next digit (2) from the dividend after 33, then repeat: 332 / 61

Let's proceed to step 5:
61 can be fit into 332 5 times, resulting in a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 345.0
If we take 305 away from 332, we end up with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 61

Going ahead to step 6:
If we divide 271 by 61, we get 4 and a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 3454.0
If we take 244 away from 271, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
270 divided by 61 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3454.4
Subtracting 244 from 270 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
If we divide 260 by 61, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 3454.44
Deduct 244 from 260 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 3454.44 with a remainder of 0.016.
