30987981 divided by 291 
The aim is to understand the frequency of 291 in 30987981.

Moving on to step 1:
If we divide 3 by 291, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 291

Let's proceed to step 2:
If we divide 30 by 291, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 291

Let's proceed to step 3:
The number 291 fits into 309 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 291 from 309, we get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 291

Going ahead to step 4:
291 can be fit into 188 0 times, resulting in a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 188 and we're left with 188.
Bring next digit (7) of the dividend behind the 188 and repeat the process: 1887 / 291

Let's proceed to step 5:
The number 291 fits into 1887 6 times, leaving a remainder of 141.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 1746 from 1887 leaves us with 141.
Include the next digit (9) from the dividend after 141, then repeat: 1419 / 291

On to step 6:
The number 291 fits into 1419 4 times, leaving a remainder of 255.
Put 4 as the next digit of the answer. 
Result so far: 1064.0
Subtracting 1164 from 1419 leaves us with 255.
Fetch the next digit (8) from the dividend, attach it to 255 and continue: 2558 / 291

Let's proceed to step 7:
When dividing 2558 by 291, we get 8 with a remainder of 230.
Write down 8 as next digit of the result. 
Result so far: 10648.0
Subtracting 2328 from 2558 leaves us with 230.
Fetch the next digit (1) from the dividend, attach it to 230 and continue: 2301 / 291

Moving on to step 8:
If we divide 2301 by 291, we get 7 and a remainder of 264.
Use 7 as the next digit of our solution. 
Result so far: 106487.0
If we take 2037 away from 2301, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 9:
2640 divided by 291 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 106487.9
Subtract 2619 from 2640 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
If we divide 210 by 291, we get 0 and a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 106487.9
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 11:
291 goes into 2100 7 times with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 106487.907
Subtract 2037 from 2100 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 12:
When dividing 630 by 291, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 106487.9072
Deduct 582 from 630 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
480 divided by 291 is 1 with a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 106487.90721
Deduct 291 from 480 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 14:
291 goes into 1890 6 times with a remainder of 144.
The next digit of our result is 6. 
Result so far: 106487.907216
Deduct 1746 from 1890 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 15:
The number 291 fits into 1440 4 times, leaving a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 106487.9072164
Deduct 1164 from 1440 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 16:
2760 divided by 291 is 9 with a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 106487.90721649
The remainder is 141 after subtracting 2619 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

The quotient of the division is 106487.90721649, and the remainder is 1.41e-07.
