978930 divided by 31 
Our goal is to divide 978930 by 31.

Let's proceed to step 1:
9 divided by 31 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 31

Let's proceed to step 2:
31 can be fit into 97 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 93 from 97 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 31

Let's proceed to step 3:
The number 31 fits into 48 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 31 from 48 leaves us with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 31

Let's proceed to step 4:
When dividing 179 by 31, we get 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 315.0
Subtract 155 from 179 to get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 31

Moving on to step 5:
The number 31 fits into 243 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 3157.0
If we subtract 217 from 243, we get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 31

Moving on to step 6:
260 divided by 31 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 31578.0
If we subtract 248 from 260, we 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:
When dividing 120 by 31, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 31578.3
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.

Step 8:
31 goes into 270 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 31578.38
Deduct 248 from 270 and we're left 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.

Going ahead to step 9:
When dividing 220 by 31, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 31578.387
If we subtract 217 from 220, we get 3.
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:
30 divided by 31 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 31578.387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
31 can be fit into 300 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 31578.38709
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
The number 31 fits into 210 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 31578.387096
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:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 31578.3870967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
When dividing 230 by 31, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 31578.38709677
Deduct 217 from 230 and we're left 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.

After the division, we end up with 31578.38709677 and a remainder of 1.3e-08.
