We look at the division of 13220722 by 310 
We want to figure out the number of times 13220722 can be divided by 310.

On to step 1:
310 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 310

Going ahead to step 2:
310 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 310

Moving on to step 3:
If we divide 132 by 310, we get 0 and a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 132 leaves us with 132.
Bring next digit (2) of the dividend behind the 132 and repeat the process: 1322 / 310

Step 4:
310 goes into 1322 4 times with a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 1240 away from 1322, we end up with 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 310

Going ahead to step 5:
If we divide 820 by 310, we get 2 and a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 200 after subtracting 620 from 820.
Bring next digit (7) of the dividend behind the 200 and repeat the process: 2007 / 310

Advancing to step 6:
310 can be fit into 2007 6 times, resulting in a remainder of 147.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
Deduct 1860 from 2007 and we're left with 147.
Bring next digit (2) of the dividend behind the 147 and repeat the process: 1472 / 310

Let's proceed to step 7:
The number 310 fits into 1472 4 times, leaving a remainder of 232.
Put 4 as the next digit of the answer. 
Result so far: 4264.0
Deduct 1240 from 1472 and we're left with 232.
Fetch the next digit (2) from the dividend, attach it to 232 and continue: 2322 / 310

On to step 8:
2322 divided by 310 is 7 with a remainder of 152.
Record the quotient 7 as the next digit in the result. 
Result so far: 42647.0
Deduct 2170 from 2322 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 9:
The number 310 fits into 1520 4 times, leaving a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 42647.4
Deduct 1240 from 1520 and we're left 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.

Moving on to step 10:
The number 310 fits into 2800 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 42647.49
Deduct 2790 from 2800 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 310 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 42647.49
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
310 can be fit into 1000 3 times, resulting in a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 42647.4903
Subtracting 930 from 1000 leaves us 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.

Step 13:
If we divide 700 by 310, we get 2 and a remainder of 80.
The next digit of our result is 2. 
Result so far: 42647.49032
The remainder is 80 after subtracting 620 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
The number 310 fits into 800 2 times, leaving a remainder of 180.
The next digit of our result is 2. 
Result so far: 42647.490322
Subtract 620 from 800 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 42647.490322 with a remaining 1.8e-05.
