Let's divide 659903 by 31
Let's see how many times 31 fits into 659903.

Step 1:
31 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 31

Step 2:
The number 31 fits into 65 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 62 from 65, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 31

Moving on to step 3:
When dividing 39 by 31, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 8 after subtracting 31 from 39.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 31

Moving on to step 4:
When dividing 89 by 31, we get 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Subtract 62 from 89 to get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 31

Going ahead to step 5:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2128.0
The remainder is 22 after subtracting 248 from 270.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 31

Let's proceed to step 6:
If we divide 223 by 31, we get 7 and a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 21287.0
If we subtract 217 from 223, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 31 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 21287.1
If we subtract 31 from 60, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
290 divided by 31 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 21287.19
The remainder is 11 after subtracting 279 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 31, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 21287.193
Subtracting 93 from 110 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
When dividing 170 by 31, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 21287.1935
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 31, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 21287.19354
Subtracting 124 from 150 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.

Going ahead to step 12:
260 divided by 31 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 21287.193548
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
When dividing 120 by 31, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 21287.1935483
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 21287.19354838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 21287.19354838 and a remainder of 2.2e-08.
