We're dividing 869190 by 31 
Our goal is to divide 869190 by 31.

Let's proceed to step 1:
31 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 31

On to step 2:
The number 31 fits into 86 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 62 away from 86, we end up with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 31

Going ahead to step 3:
If we divide 249 by 31, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 248 from 249 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 31

Advancing to step 4:
The number 31 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 280.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 31

Moving on to step 5:
31 goes into 119 3 times with a remainder of 26.
The next digit of our result is 3. 
Result so far: 2803.0
Subtract 93 from 119 to get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 31

Step 6:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 28038.0
Subtract 248 from 260 to get 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 7:
31 goes into 120 3 times with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 28038.3
If we subtract 93 from 120, we 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.

Going ahead to step 8:
31 goes into 270 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 28038.38
The remainder is 22 after subtracting 248 from 270.
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 9:
If we divide 220 by 31, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 28038.387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 31 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 28038.387
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
31 goes into 300 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 28038.38709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
210 divided by 31 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 28038.387096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
240 divided by 31 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 28038.3870967
Deduct 217 from 240 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
31 can be fit into 230 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 28038.38709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 28038.38709677 with a balance of 1.3e-08.
