Let's divide 64437599 by 797
The aim is to understand the frequency of 797 in 64437599.

Advancing to step 1:
The number 797 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 797

Going ahead to step 2:
797 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 797

Going ahead to step 3:
When dividing 644 by 797, we get 0 with a remainder of 644.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 644 after subtracting 0 from 644.
Append the next digit (3) from the dividend to 644 and continue with: 6443 / 797

Moving on to step 4:
The number 797 fits into 6443 8 times, leaving a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6376 from 6443 to get 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 797

Advancing to step 5:
677 divided by 797 is 0 with a remainder of 677.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 677 to get 677.
Grab the next digit (5) from the dividend, add it to 677, then carry on: 6775 / 797

Going ahead to step 6:
6775 divided by 797 is 8 with a remainder of 399.
The number 8 becomes the next digit in our result. 
Result so far: 808.0
The remainder is 399 after subtracting 6376 from 6775.
Append the next digit (9) from the dividend to 399 and continue with: 3999 / 797

On to step 7:
797 goes into 3999 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 8085.0
Subtracting 3985 from 3999 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 797

Advancing to step 8:
797 goes into 149 0 times with a remainder of 149.
Write down 0 as next digit of the result. 
Result so far: 80850.0
If we take 0 away from 149, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 9:
797 goes into 1490 1 times with a remainder of 693.
Put 1 as the next digit of the answer. 
Result so far: 80850.1
Subtract 797 from 1490 to get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Advancing to step 10:
797 can be fit into 6930 8 times, resulting in a remainder of 554.
Put 8 as the next digit of the answer. 
Result so far: 80850.18
Subtracting 6376 from 6930 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 11:
When dividing 5540 by 797, we get 6 with a remainder of 758.
Record the quotient 6 as the next digit in the result. 
Result so far: 80850.186
If we subtract 4782 from 5540, we get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

On to step 12:
If we divide 7580 by 797, we get 9 and a remainder of 407.
Use 9 as the next digit of our solution. 
Result so far: 80850.1869
The remainder is 407 after subtracting 7173 from 7580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Let's proceed to step 13:
797 can be fit into 4070 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 80850.18695
If we subtract 3985 from 4070, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 14:
The number 797 fits into 850 1 times, leaving a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 80850.186951
If we take 797 away from 850, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 15:
When dividing 530 by 797, we get 0 with a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 80850.186951
If we take 0 away from 530, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 16:
When dividing 5300 by 797, we get 6 with a remainder of 518.
Put 6 as the next digit of the answer. 
Result so far: 80850.18695106
Subtracting 4782 from 5300 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

The final outcome is 80850.18695106, with a leftover of 5.18e-07.
