646863 ÷ 59 
Let's see how many times 59 fits into 646863.

Moving on to step 1:
59 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 59

Moving on to step 2:
59 can be fit into 64 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 59 from 64.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 59

Advancing to step 3:
59 can be fit into 56 0 times, resulting in a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 56 to get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 59

Going ahead to step 4:
59 goes into 568 9 times with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtracting 531 from 568 leaves us with 37.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 59

Going ahead to step 5:
59 goes into 376 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 1096.0
Subtract 354 from 376 to get 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 59

Moving on to step 6:
59 goes into 223 3 times with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 10963.0
If we subtract 177 from 223, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
59 can be fit into 460 7 times, resulting in a remainder of 47.
The next digit of our result is 7. 
Result so far: 10963.7
Subtracting 413 from 460 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
59 goes into 470 7 times with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 10963.77
If we take 413 away from 470, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 10963.77 with a remainder of 0.057.
