3107354 ÷ 309 
We want to figure out the number of times 3107354 can be divided by 309.

Advancing to step 1:
309 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 309

Moving on to step 2:
If we divide 31 by 309, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 309

Let's proceed to step 3:
309 can be fit into 310 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 309 from 310, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 309

Let's proceed to step 4:
If we divide 17 by 309, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 309

Advancing to step 5:
The number 309 fits into 173 0 times, leaving a remainder of 173.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 173 leaves us with 173.
Grab the next digit (5) from the dividend, add it to 173, then carry on: 1735 / 309

Going ahead to step 6:
309 goes into 1735 5 times with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
Subtract 1545 from 1735 to get 190.
Fetch the next digit (4) from the dividend, attach it to 190 and continue: 1904 / 309

Going ahead to step 7:
309 goes into 1904 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 10056.0
If we take 1854 away from 1904, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
309 goes into 500 1 times with a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 10056.1
Deduct 309 from 500 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 9:
The number 309 fits into 1910 6 times, leaving a remainder of 56.
The next digit of our result is 6. 
Result so far: 10056.16
Subtract 1854 from 1910 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
When dividing 560 by 309, we get 1 with a remainder of 251.
Record the quotient 1 as the next digit in the result. 
Result so far: 10056.161
The remainder is 251 after subtracting 309 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Advancing to step 11:
The number 309 fits into 2510 8 times, leaving a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 10056.1618
If we take 2472 away from 2510, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
309 can be fit into 380 1 times, resulting in a remainder of 71.
The next digit of our result is 1. 
Result so far: 10056.16181
Deduct 309 from 380 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
The number 309 fits into 710 2 times, leaving a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 10056.161812
Subtracting 618 from 710 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
The number 309 fits into 920 2 times, leaving a remainder of 302.
Record the quotient 2 as the next digit in the result. 
Result so far: 10056.1618122
Subtracting 618 from 920 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Our division results in 10056.1618122 with a remaining 3.02e-06.
