402309 ÷ 61 
We want to divide 402309 by 61.

Step 1:
61 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 61

Step 2:
The number 61 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 61

Going ahead to step 3:
402 divided by 61 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 366 from 402 to get 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 61

Moving on to step 4:
363 divided by 61 is 5 with a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 305 from 363 to get 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 61

Going ahead to step 5:
61 can be fit into 580 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 659.0
The remainder is 31 after subtracting 549 from 580.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 61

Step 6:
319 divided by 61 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 6595.0
Subtracting 305 from 319 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
61 goes into 140 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 6595.2
Deduct 122 from 140 and we're left 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.

Step 8:
180 divided by 61 is 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 6595.22
The remainder is 58 after subtracting 122 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 6595.22 with a remainder of 0.058.
