608639 ÷ 31 
Our goal is to divide 608639 by 31.

Step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 31

Moving on to step 2:
60 divided by 31 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 31 from 60, we get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 31

Moving on to step 3:
The number 31 fits into 298 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 279 from 298 leaves us with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 31

Advancing to step 4:
31 goes into 196 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 196.0
If we take 186 away from 196, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 31

Going ahead to step 5:
103 divided by 31 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1963.0
If we subtract 93 from 103, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 31

Let's proceed to step 6:
When dividing 109 by 31, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 19633.0
The remainder is 16 after subtracting 93 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 31, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19633.5
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 31, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 19633.51
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 19633.516
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
31 goes into 40 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 19633.5161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 19633.51612
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 31 fits into 280 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 19633.516129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
If we divide 10 by 31, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 19633.516129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
If we divide 100 by 31, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 19633.51612903
If we take 93 away from 100, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 19633.51612903 with a remaining 7e-09.
