13370345 ÷ 721 
Let's see how many times 721 fits into 13370345.

Going ahead to step 1:
When dividing 1 by 721, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 721

Going ahead to step 2:
721 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 721

Advancing to step 3:
The number 721 fits into 133 0 times, leaving a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 133, we get 133.
Append the next digit (7) from the dividend to 133 and continue with: 1337 / 721

Step 4:
721 goes into 1337 1 times with a remainder of 616.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 721 from 1337, we get 616.
Take the next digit (0) from the dividend and append it to 616, then repeat: 6160 / 721

Moving on to step 5:
721 can be fit into 6160 8 times, resulting in a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 5768 from 6160 and we're left with 392.
Fetch the next digit (3) from the dividend, attach it to 392 and continue: 3923 / 721

Moving on to step 6:
The number 721 fits into 3923 5 times, leaving a remainder of 318.
The next digit of our result is 5. 
Result so far: 185.0
If we take 3605 away from 3923, we end up with 318.
Take the next digit (4) from the dividend and append it to 318, then repeat: 3184 / 721

Let's proceed to step 7:
721 goes into 3184 4 times with a remainder of 300.
The next digit of our result is 4. 
Result so far: 1854.0
Deduct 2884 from 3184 and we're left with 300.
Fetch the next digit (5) from the dividend, attach it to 300 and continue: 3005 / 721

Going ahead to step 8:
If we divide 3005 by 721, we get 4 and a remainder of 121.
Put 4 as the next digit of the answer. 
Result so far: 18544.0
The remainder is 121 after subtracting 2884 from 3005.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
When dividing 1210 by 721, we get 1 with a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 18544.1
If we take 721 away from 1210, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 10:
The number 721 fits into 4890 6 times, leaving a remainder of 564.
The next digit of our result is 6. 
Result so far: 18544.16
Deduct 4326 from 4890 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 11:
721 goes into 5640 7 times with a remainder of 593.
Record the quotient 7 as the next digit in the result. 
Result so far: 18544.167
Deduct 5047 from 5640 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Step 12:
If we divide 5930 by 721, we get 8 and a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 18544.1678
Subtract 5768 from 5930 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 13:
When dividing 1620 by 721, we get 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 18544.16782
Subtract 1442 from 1620 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 14:
721 can be fit into 1780 2 times, resulting in a remainder of 338.
The number 2 becomes the next digit in our result. 
Result so far: 18544.167822
Subtract 1442 from 1780 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final result is 18544.167822 with a remainder of 3.38e-05.
