We look at the division of 90267809 by 797 
The aim is to understand the frequency of 797 in 90267809.

Moving on to step 1:
When dividing 9 by 797, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 797

Going ahead to step 2:
797 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 797

Advancing to step 3:
If we divide 902 by 797, we get 1 and a remainder of 105.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 797 from 902 to get 105.
Bring next digit (6) of the dividend behind the 105 and repeat the process: 1056 / 797

Advancing to step 4:
797 can be fit into 1056 1 times, resulting in a remainder of 259.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 797 from 1056 to get 259.
Fetch the next digit (7) from the dividend, attach it to 259 and continue: 2597 / 797

On to step 5:
797 can be fit into 2597 3 times, resulting in a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtracting 2391 from 2597 leaves us with 206.
Append the next digit (8) from the dividend to 206 and continue with: 2068 / 797

Going ahead to step 6:
The number 797 fits into 2068 2 times, leaving a remainder of 474.
Use 2 as the next digit of our solution. 
Result so far: 1132.0
If we take 1594 away from 2068, we end up with 474.
Grab the next digit (0) from the dividend, add it to 474, then carry on: 4740 / 797

Moving on to step 7:
If we divide 4740 by 797, we get 5 and a remainder of 755.
Put 5 as the next digit of the answer. 
Result so far: 11325.0
Subtracting 3985 from 4740 leaves us with 755.
Take the next digit (9) from the dividend and append it to 755, then repeat: 7559 / 797

Moving on to step 8:
The number 797 fits into 7559 9 times, leaving a remainder of 386.
The number 9 becomes the next digit in our result. 
Result so far: 113259.0
Subtracting 7173 from 7559 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 9:
797 goes into 3860 4 times with a remainder of 672.
Use 4 as the next digit of our solution. 
Result so far: 113259.4
Deduct 3188 from 3860 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 10:
6720 divided by 797 is 8 with a remainder of 344.
The next digit of our result is 8. 
Result so far: 113259.48
Deduct 6376 from 6720 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 11:
When dividing 3440 by 797, we get 4 with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 113259.484
Subtract 3188 from 3440 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 12:
When dividing 2520 by 797, we get 3 with a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 113259.4843
Subtracting 2391 from 2520 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 13:
1290 divided by 797 is 1 with a remainder of 493.
Put 1 as the next digit of the answer. 
Result so far: 113259.48431
Deduct 797 from 1290 and we're left with 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 14:
797 can be fit into 4930 6 times, resulting in a remainder of 148.
Use 6 as the next digit of our solution. 
Result so far: 113259.484316
The remainder is 148 after subtracting 4782 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 15:
When dividing 1480 by 797, we get 1 with a remainder of 683.
The next digit of our result is 1. 
Result so far: 113259.4843161
Deduct 797 from 1480 and we're left with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Going ahead to step 16:
797 can be fit into 6830 8 times, resulting in a remainder of 454.
The number 8 becomes the next digit in our result. 
Result so far: 113259.48431618
If we subtract 6376 from 6830, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

The final outcome is 113259.48431618, with a leftover of 4.54e-07.
