19870242 ÷ 331 
We want to figure out the number of times 19870242 can be divided by 331.

Let's proceed to step 1:
331 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 331

Advancing to step 2:
331 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 331

Going ahead to step 3:
The number 331 fits into 198 0 times, leaving a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 198, we end up with 198.
Append the next digit (7) from the dividend to 198 and continue with: 1987 / 331

Advancing to step 4:
1987 divided by 331 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 1986 from 1987 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 331

Let's proceed to step 5:
The number 331 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 10, we end up with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 331

Advancing to step 6:
The number 331 fits into 102 0 times, leaving a remainder of 102.
The next digit of our result is 0. 
Result so far: 600.0
Subtracting 0 from 102 leaves us with 102.
Take the next digit (4) from the dividend and append it to 102, then repeat: 1024 / 331

Going ahead to step 7:
The number 331 fits into 1024 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 6003.0
If we subtract 993 from 1024, we get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 331

Moving on to step 8:
312 divided by 331 is 0 with a remainder of 312.
Use 0 as the next digit of our solution. 
Result so far: 60030.0
The remainder is 312 after subtracting 0 from 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 9:
When dividing 3120 by 331, we get 9 with a remainder of 141.
The next digit of our result is 9. 
Result so far: 60030.9
If we take 2979 away from 3120, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 10:
331 can be fit into 1410 4 times, resulting in a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 60030.94
Subtract 1324 from 1410 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 11:
331 goes into 860 2 times with a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 60030.942
Deduct 662 from 860 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 12:
331 can be fit into 1980 5 times, resulting in a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 60030.9425
Deduct 1655 from 1980 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 13:
If we divide 3250 by 331, we get 9 and a remainder of 271.
The next digit of our result is 9. 
Result so far: 60030.94259
Subtracting 2979 from 3250 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 14:
The number 331 fits into 2710 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 60030.942598
Subtract 2648 from 2710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 15:
331 goes into 620 1 times with a remainder of 289.
The next digit of our result is 1. 
Result so far: 60030.9425981
Subtract 331 from 620 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 16:
331 goes into 2890 8 times with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 60030.94259818
The remainder is 242 after subtracting 2648 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Our division results in 60030.94259818 with a remaining 2.42e-07.
