6495914 ÷ 991 
The aim is to understand the frequency of 991 in 6495914.

Moving on to step 1:
6 divided by 991 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 991

On to step 2:
If we divide 64 by 991, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 991

On to step 3:
If we divide 649 by 991, we get 0 and a remainder of 649.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 649 after subtracting 0 from 649.
Grab the next digit (5) from the dividend, add it to 649, then carry on: 6495 / 991

Advancing to step 4:
991 goes into 6495 6 times with a remainder of 549.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5946 away from 6495, we end up with 549.
Bring next digit (9) of the dividend behind the 549 and repeat the process: 5499 / 991

Advancing to step 5:
5499 divided by 991 is 5 with a remainder of 544.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we take 4955 away from 5499, we end up with 544.
Include the next digit (1) from the dividend after 544, then repeat: 5441 / 991

Let's proceed to step 6:
If we divide 5441 by 991, we get 5 and a remainder of 486.
The next digit of our result is 5. 
Result so far: 655.0
Subtract 4955 from 5441 to get 486.
Take the next digit (4) from the dividend and append it to 486, then repeat: 4864 / 991

Step 7:
991 can be fit into 4864 4 times, resulting in a remainder of 900.
Use 4 as the next digit of our solution. 
Result so far: 6554.0
Subtracting 3964 from 4864 leaves us with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

On to step 8:
If we divide 9000 by 991, we get 9 and a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 6554.9
If we take 8919 away from 9000, 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.

On to step 9:
The number 991 fits into 810 0 times, leaving a remainder of 810.
Use 0 as the next digit of our solution. 
Result so far: 6554.9
If we subtract 0 from 810, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 10:
The number 991 fits into 8100 8 times, leaving a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 6554.908
The remainder is 172 after subtracting 7928 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 11:
The number 991 fits into 1720 1 times, leaving a remainder of 729.
Use 1 as the next digit of our solution. 
Result so far: 6554.9081
The remainder is 729 after subtracting 991 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Moving on to step 12:
If we divide 7290 by 991, we get 7 and a remainder of 353.
Record the quotient 7 as the next digit in the result. 
Result so far: 6554.90817
If we take 6937 away from 7290, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 13:
If we divide 3530 by 991, we get 3 and a remainder of 557.
Use 3 as the next digit of our solution. 
Result so far: 6554.908173
If we subtract 2973 from 3530, we get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 14:
The number 991 fits into 5570 5 times, leaving a remainder of 615.
Write down 5 as next digit of the result. 
Result so far: 6554.9081735
The remainder is 615 after subtracting 4955 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 15:
The number 991 fits into 6150 6 times, leaving a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 6554.90817356
Deduct 5946 from 6150 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final result is 6554.90817356 with a remainder of 2.04e-07.
