Let's divide 931389 by 31
We're looking to find how many times 31 goes into 931389.

On to step 1:
When dividing 9 by 31, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 31

Going ahead to step 2:
31 can be fit into 93 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 93 from 93 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 31

Advancing to step 3:
When dividing 1 by 31, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 31

Advancing to step 4:
The number 31 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 300.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 31

Let's proceed to step 5:
31 can be fit into 138 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3004.0
The remainder is 14 after subtracting 124 from 138.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 31

Step 6:
If we divide 149 by 31, we get 4 and a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 30044.0
Deduct 124 from 149 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
31 can be fit into 250 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 30044.8
If we take 248 away from 250, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 31 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 30044.8
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 31 fits into 200 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 30044.806
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 30044.8064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
31 goes into 160 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 30044.80645
The remainder is 5 after subtracting 155 from 160.
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 12:
If we divide 50 by 31, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 30044.806451
If we subtract 31 from 50, we 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.

Going ahead to step 13:
When dividing 190 by 31, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 30044.8064516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
If we divide 40 by 31, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 30044.80645161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 30044.80645161 with a balance of 9e-09.
