We're dividing 27025063 by 991 
The aim is to understand the frequency of 991 in 27025063.

Moving on to step 1:
If we divide 2 by 991, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 991

Advancing to step 2:
991 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 991

Going ahead to step 3:
The number 991 fits into 270 0 times, leaving a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 270 after subtracting 0 from 270.
Bring next digit (2) of the dividend behind the 270 and repeat the process: 2702 / 991

Step 4:
When dividing 2702 by 991, we get 2 with a remainder of 720.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1982 away from 2702, we end up with 720.
Grab the next digit (5) from the dividend, add it to 720, then carry on: 7205 / 991

Going ahead to step 5:
When dividing 7205 by 991, we get 7 with a remainder of 268.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtract 6937 from 7205 to get 268.
Bring next digit (0) of the dividend behind the 268 and repeat the process: 2680 / 991

Going ahead to step 6:
If we divide 2680 by 991, we get 2 and a remainder of 698.
Put 2 as the next digit of the answer. 
Result so far: 272.0
Subtract 1982 from 2680 to get 698.
Grab the next digit (6) from the dividend, add it to 698, then carry on: 6986 / 991

Going ahead to step 7:
When dividing 6986 by 991, we get 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 2727.0
Deduct 6937 from 6986 and we're left with 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 991

Moving on to step 8:
493 divided by 991 is 0 with a remainder of 493.
The number 0 becomes the next digit in our result. 
Result so far: 27270.0
Subtract 0 from 493 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 9:
The number 991 fits into 4930 4 times, leaving a remainder of 966.
Record the quotient 4 as the next digit in the result. 
Result so far: 27270.4
Subtracting 3964 from 4930 leaves us with 966.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9660, and continue the process.

Moving on to step 10:
When dividing 9660 by 991, we get 9 with a remainder of 741.
The next digit of our result is 9. 
Result so far: 27270.49
Subtract 8919 from 9660 to get 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Step 11:
991 goes into 7410 7 times with a remainder of 473.
The number 7 becomes the next digit in our result. 
Result so far: 27270.497
Subtracting 6937 from 7410 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 12:
The number 991 fits into 4730 4 times, leaving a remainder of 766.
Put 4 as the next digit of the answer. 
Result so far: 27270.4974
If we subtract 3964 from 4730, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

On to step 13:
991 can be fit into 7660 7 times, resulting in a remainder of 723.
The next digit of our result is 7. 
Result so far: 27270.49747
Deduct 6937 from 7660 and we're left with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Step 14:
991 goes into 7230 7 times with a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 27270.497477
The remainder is 293 after subtracting 6937 from 7230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

The final result is 27270.497477 with a remainder of 2.93e-05.
