We're dividing 721585 by 31 
Let's see how many times 31 fits into 721585.

Let's proceed to step 1:
When dividing 7 by 31, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 31

Moving on to step 2:
When dividing 72 by 31, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 72 leaves us with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 31

Advancing to step 3:
When dividing 101 by 31, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 8 after subtracting 93 from 101.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 31

Moving on to step 4:
When dividing 85 by 31, we get 2 with a remainder of 23.
The next digit of our result is 2. 
Result so far: 232.0
The remainder is 23 after subtracting 62 from 85.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 31

Advancing to step 5:
238 divided by 31 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 2327.0
Deduct 217 from 238 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 31

Going ahead to step 6:
31 can be fit into 215 6 times, resulting in a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 23276.0
Subtract 186 from 215 to 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.

Moving on to step 7:
31 can be fit into 290 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 23276.9
If we take 279 away from 290, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
If we divide 110 by 31, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 23276.93
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
31 goes into 170 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 23276.935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 31, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 23276.9354
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
260 divided by 31 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 23276.93548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 23276.935483
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.

On to step 13:
When dividing 270 by 31, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 23276.9354838
If we take 248 away from 270, we end up 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.

Advancing to step 14:
When dividing 220 by 31, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 23276.93548387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 23276.93548387 with a balance of 3e-09.
