724909 ÷ 31 
We want to figure out the number of times 724909 can be divided by 31.

Let's proceed to step 1:
31 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 31

Moving on to step 2:
31 goes into 72 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 10 after subtracting 62 from 72.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 31

Advancing to step 3:
When dividing 104 by 31, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 93 away from 104, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 31

Going ahead to step 4:
When dividing 119 by 31, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 233.0
If we take 93 away from 119, we end up with 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 31

Advancing to step 5:
31 goes into 260 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2338.0
Subtract 248 from 260 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 31

Moving on to step 6:
129 divided by 31 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 23384.0
If we subtract 124 from 129, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
31 goes into 50 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 23384.1
Subtracting 31 from 50 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 23384.16
Subtract 186 from 190 to 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.

Advancing to step 9:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 23384.161
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.

On to step 10:
31 can be fit into 90 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 23384.1612
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 23384.16129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
If we divide 10 by 31, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 23384.16129
Subtracting 0 from 10 leaves us 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 13:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 23384.1612903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 23384.16129032
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 23384.16129032 with a remainder of 8e-09.
