67432315 divided by 991 
The aim is to understand the frequency of 991 in 67432315.

Step 1:
When dividing 6 by 991, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 991

Let's proceed to step 2:
67 divided by 991 is 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 991

Step 3:
If we divide 674 by 991, we get 0 and a remainder of 674.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 674 after subtracting 0 from 674.
Bring next digit (3) of the dividend behind the 674 and repeat the process: 6743 / 991

Moving on to step 4:
991 goes into 6743 6 times with a remainder of 797.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 5946 from 6743, we get 797.
Fetch the next digit (2) from the dividend, attach it to 797 and continue: 7972 / 991

On to step 5:
991 can be fit into 7972 8 times, resulting in a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 44 after subtracting 7928 from 7972.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 991

On to step 6:
When dividing 443 by 991, we get 0 with a remainder of 443.
Put 0 as the next digit of the answer. 
Result so far: 680.0
If we subtract 0 from 443, we get 443.
Take the next digit (1) from the dividend and append it to 443, then repeat: 4431 / 991

On to step 7:
If we divide 4431 by 991, we get 4 and a remainder of 467.
Record the quotient 4 as the next digit in the result. 
Result so far: 6804.0
If we take 3964 away from 4431, we end up with 467.
Fetch the next digit (5) from the dividend, attach it to 467 and continue: 4675 / 991

Moving on to step 8:
4675 divided by 991 is 4 with a remainder of 711.
Write down 4 as next digit of the result. 
Result so far: 68044.0
The remainder is 711 after subtracting 3964 from 4675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Moving on to step 9:
991 goes into 7110 7 times with a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 68044.7
Deduct 6937 from 7110 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 10:
1730 divided by 991 is 1 with a remainder of 739.
Write down 1 as next digit of the result. 
Result so far: 68044.71
If we subtract 991 from 1730, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Going ahead to step 11:
991 can be fit into 7390 7 times, resulting in a remainder of 453.
The next digit of our result is 7. 
Result so far: 68044.717
If we take 6937 away from 7390, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 12:
The number 991 fits into 4530 4 times, leaving a remainder of 566.
The next digit of our result is 4. 
Result so far: 68044.7174
If we take 3964 away from 4530, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 13:
991 can be fit into 5660 5 times, resulting in a remainder of 705.
The number 5 becomes the next digit in our result. 
Result so far: 68044.71745
Subtracting 4955 from 5660 leaves us with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Let's proceed to step 14:
The number 991 fits into 7050 7 times, leaving a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 68044.717457
Subtract 6937 from 7050 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 15:
When dividing 1130 by 991, we get 1 with a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 68044.7174571
Subtract 991 from 1130 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 16:
When dividing 1390 by 991, we get 1 with a remainder of 399.
Put 1 as the next digit of the answer. 
Result so far: 68044.71745711
The remainder is 399 after subtracting 991 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

In conclusion, the division gives 68044.71745711 with a balance of 3.99e-07.
