Let's divide 15349727 by 321
We want to figure out the number of times 15349727 can be divided by 321.

Step 1:
When dividing 1 by 321, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 321

On to step 2:
321 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 321

Going ahead to step 3:
153 divided by 321 is 0 with a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 153, we get 153.
Bring next digit (4) of the dividend behind the 153 and repeat the process: 1534 / 321

On to step 4:
When dividing 1534 by 321, we get 4 with a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1284 away from 1534, we end up with 250.
Take the next digit (9) from the dividend and append it to 250, then repeat: 2509 / 321

Advancing to step 5:
If we divide 2509 by 321, we get 7 and a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 2247 from 2509, we get 262.
Take the next digit (7) from the dividend and append it to 262, then repeat: 2627 / 321

On to step 6:
When dividing 2627 by 321, we get 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 478.0
Deduct 2568 from 2627 and we're left with 59.
Include the next digit (2) from the dividend after 59, then repeat: 592 / 321

On to step 7:
592 divided by 321 is 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 4781.0
Subtract 321 from 592 to get 271.
Grab the next digit (7) from the dividend, add it to 271, then carry on: 2717 / 321

Let's proceed to step 8:
321 goes into 2717 8 times with a remainder of 149.
Write down 8 as next digit of the result. 
Result so far: 47818.0
Deduct 2568 from 2717 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
321 can be fit into 1490 4 times, resulting in a remainder of 206.
Record the quotient 4 as the next digit in the result. 
Result so far: 47818.4
Deduct 1284 from 1490 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 10:
The number 321 fits into 2060 6 times, leaving a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 47818.46
Subtracting 1926 from 2060 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 11:
321 can be fit into 1340 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 47818.464
Subtracting 1284 from 1340 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
If we divide 560 by 321, we get 1 and a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 47818.4641
Deduct 321 from 560 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 13:
When dividing 2390 by 321, we get 7 with a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 47818.46417
Subtracting 2247 from 2390 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 14:
When dividing 1430 by 321, we get 4 with a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 47818.464174
The remainder is 146 after subtracting 1284 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 15:
1460 divided by 321 is 4 with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 47818.4641744
If we take 1284 away from 1460, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 47818.4641744, and the remainder is 1.76e-06.
