We look at the division of 79942595 by 997 
The aim is to understand the frequency of 997 in 79942595.

Moving on to step 1:
When dividing 7 by 997, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 997

Advancing to step 2:
997 goes into 79 0 times with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 997

Going ahead to step 3:
If we divide 799 by 997, we get 0 and a remainder of 799.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 799 to get 799.
Fetch the next digit (4) from the dividend, attach it to 799 and continue: 7994 / 997

Let's proceed to step 4:
If we divide 7994 by 997, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7976 away from 7994, we end up with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 997

On to step 5:
The number 997 fits into 182 0 times, leaving a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 182 and we're left with 182.
Bring next digit (5) of the dividend behind the 182 and repeat the process: 1825 / 997

Advancing to step 6:
997 goes into 1825 1 times with a remainder of 828.
Put 1 as the next digit of the answer. 
Result so far: 801.0
The remainder is 828 after subtracting 997 from 1825.
Include the next digit (9) from the dividend after 828, then repeat: 8289 / 997

On to step 7:
If we divide 8289 by 997, we get 8 and a remainder of 313.
Use 8 as the next digit of our solution. 
Result so far: 8018.0
If we subtract 7976 from 8289, we get 313.
Grab the next digit (5) from the dividend, add it to 313, then carry on: 3135 / 997

Going ahead to step 8:
997 goes into 3135 3 times with a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 80183.0
If we take 2991 away from 3135, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 9:
997 can be fit into 1440 1 times, resulting in a remainder of 443.
Put 1 as the next digit of the answer. 
Result so far: 80183.1
Subtract 997 from 1440 to get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 10:
997 goes into 4430 4 times with a remainder of 442.
The number 4 becomes the next digit in our result. 
Result so far: 80183.14
Subtracting 3988 from 4430 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 11:
4420 divided by 997 is 4 with a remainder of 432.
Write down 4 as next digit of the result. 
Result so far: 80183.144
If we take 3988 away from 4420, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The quotient of the division is 80183.144, and the remainder is 0.0432.
