31311228 ÷ 685 
We're looking to find how many times 685 goes into 31311228.

Let's proceed to step 1:
When dividing 3 by 685, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 685

Moving on to step 2:
If we divide 31 by 685, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 685

Going ahead to step 3:
685 can be fit into 313 0 times, resulting in a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 313, we end up with 313.
Take the next digit (1) from the dividend and append it to 313, then repeat: 3131 / 685

Advancing to step 4:
685 goes into 3131 4 times with a remainder of 391.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2740 from 3131 to get 391.
Take the next digit (1) from the dividend and append it to 391, then repeat: 3911 / 685

Moving on to step 5:
When dividing 3911 by 685, we get 5 with a remainder of 486.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 3425 from 3911 to get 486.
Bring next digit (2) of the dividend behind the 486 and repeat the process: 4862 / 685

Advancing to step 6:
685 goes into 4862 7 times with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 457.0
Subtracting 4795 from 4862 leaves us with 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 685

Step 7:
When dividing 672 by 685, we get 0 with a remainder of 672.
The next digit of our result is 0. 
Result so far: 4570.0
Deduct 0 from 672 and we're left with 672.
Grab the next digit (8) from the dividend, add it to 672, then carry on: 6728 / 685

Step 8:
The number 685 fits into 6728 9 times, leaving a remainder of 563.
Use 9 as the next digit of our solution. 
Result so far: 45709.0
If we subtract 6165 from 6728, we get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 9:
5630 divided by 685 is 8 with a remainder of 150.
Record the quotient 8 as the next digit in the result. 
Result so far: 45709.8
If we subtract 5480 from 5630, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
1500 divided by 685 is 2 with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 45709.82
Subtract 1370 from 1500 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
The number 685 fits into 1300 1 times, leaving a remainder of 615.
Write down 1 as next digit of the result. 
Result so far: 45709.821
If we subtract 685 from 1300, we get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 12:
If we divide 6150 by 685, we get 8 and a remainder of 670.
Put 8 as the next digit of the answer. 
Result so far: 45709.8218
If we take 5480 away from 6150, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 13:
685 can be fit into 6700 9 times, resulting in a remainder of 535.
The next digit of our result is 9. 
Result so far: 45709.82189
If we take 6165 away from 6700, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 14:
If we divide 5350 by 685, we get 7 and a remainder of 555.
Record the quotient 7 as the next digit in the result. 
Result so far: 45709.821897
The remainder is 555 after subtracting 4795 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 15:
5550 divided by 685 is 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 45709.8218978
Deduct 5480 from 5550 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 16:
If we divide 700 by 685, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 45709.82189781
Subtract 685 from 700 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 45709.82189781 with a balance of 1.5e-08.
