12916789 divided by 310 
We want to figure out the number of times 12916789 can be divided by 310.

Moving on to step 1:
310 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 310

Going ahead to step 2:
The number 310 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 310

Advancing to step 3:
310 can be fit into 129 0 times, resulting in a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 129 leaves us with 129.
Include the next digit (1) from the dividend after 129, then repeat: 1291 / 310

Moving on to step 4:
310 can be fit into 1291 4 times, resulting in a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1240 from 1291 leaves us with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 310

On to step 5:
The number 310 fits into 516 1 times, leaving a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 310 from 516 and we're left with 206.
Take the next digit (7) from the dividend and append it to 206, then repeat: 2067 / 310

Moving on to step 6:
If we divide 2067 by 310, we get 6 and a remainder of 207.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
If we take 1860 away from 2067, we end up with 207.
Fetch the next digit (8) from the dividend, attach it to 207 and continue: 2078 / 310

Let's proceed to step 7:
When dividing 2078 by 310, we get 6 with a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 4166.0
Subtract 1860 from 2078 to get 218.
Grab the next digit (9) from the dividend, add it to 218, then carry on: 2189 / 310

Advancing to step 8:
2189 divided by 310 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 41667.0
If we subtract 2170 from 2189, 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.

Let's proceed to step 9:
The number 310 fits into 190 0 times, leaving a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 41667.0
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
If we divide 1900 by 310, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 41667.06
If we take 1860 away from 1900, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
310 can be fit into 400 1 times, resulting in a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 41667.061
Deduct 310 from 400 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
When dividing 900 by 310, we get 2 with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 41667.0612
Subtracting 620 from 900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 13:
When dividing 2800 by 310, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 41667.06129
The remainder is 10 after subtracting 2790 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 310, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 41667.06129
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
310 goes into 1000 3 times with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 41667.0612903
Subtract 930 from 1000 to get 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:
310 can be fit into 700 2 times, resulting in a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 41667.06129032
If we subtract 620 from 700, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 41667.06129032 and a remainder of 8e-08.
