We're dividing 15720431 by 331 
We're looking to find how many times 331 goes into 15720431.

Let's proceed to step 1:
When dividing 1 by 331, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 331

Step 2:
When dividing 15 by 331, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 331

Step 3:
331 goes into 157 0 times with a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Include the next digit (2) from the dividend after 157, then repeat: 1572 / 331

Moving on to step 4:
When dividing 1572 by 331, we get 4 with a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1324 from 1572 to get 248.
Grab the next digit (0) from the dividend, add it to 248, then carry on: 2480 / 331

Going ahead to step 5:
331 goes into 2480 7 times with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtract 2317 from 2480 to get 163.
Fetch the next digit (4) from the dividend, attach it to 163 and continue: 1634 / 331

Advancing to step 6:
331 can be fit into 1634 4 times, resulting in a remainder of 310.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
If we take 1324 away from 1634, we end up with 310.
Append the next digit (3) from the dividend to 310 and continue with: 3103 / 331

Step 7:
The number 331 fits into 3103 9 times, leaving a remainder of 124.
The next digit of our result is 9. 
Result so far: 4749.0
The remainder is 124 after subtracting 2979 from 3103.
Include the next digit (1) from the dividend after 124, then repeat: 1241 / 331

Advancing to step 8:
331 can be fit into 1241 3 times, resulting in a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 47493.0
If we take 993 away from 1241, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
The number 331 fits into 2480 7 times, leaving a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 47493.7
The remainder is 163 after subtracting 2317 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 10:
1630 divided by 331 is 4 with a remainder of 306.
Record the quotient 4 as the next digit in the result. 
Result so far: 47493.74
Subtracting 1324 from 1630 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
331 can be fit into 3060 9 times, resulting in a remainder of 81.
The next digit of our result is 9. 
Result so far: 47493.749
If we take 2979 away from 3060, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 12:
When dividing 810 by 331, we get 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 47493.7492
Subtracting 662 from 810 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 13:
331 can be fit into 1480 4 times, resulting in a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 47493.74924
The remainder is 156 after subtracting 1324 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 14:
The number 331 fits into 1560 4 times, leaving a remainder of 236.
The next digit of our result is 4. 
Result so far: 47493.749244
The remainder is 236 after subtracting 1324 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 47493.749244, and the remainder is 2.36e-05.
