We look at the division of 79894523 by 974 
The aim is to understand the frequency of 974 in 79894523.

On to step 1:
7 divided by 974 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 974

Advancing to step 2:
974 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 974

Moving on to step 3:
798 divided by 974 is 0 with a remainder of 798.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 798 leaves us with 798.
Fetch the next digit (9) from the dividend, attach it to 798 and continue: 7989 / 974

Advancing to step 4:
The number 974 fits into 7989 8 times, leaving a remainder of 197.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 197 after subtracting 7792 from 7989.
Bring next digit (4) of the dividend behind the 197 and repeat the process: 1974 / 974

Let's proceed to step 5:
If we divide 1974 by 974, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 1948 away from 1974, we end up with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 974

On to step 6:
265 divided by 974 is 0 with a remainder of 265.
Put 0 as the next digit of the answer. 
Result so far: 820.0
If we take 0 away from 265, we end up with 265.
Take the next digit (2) from the dividend and append it to 265, then repeat: 2652 / 974

Going ahead to step 7:
When dividing 2652 by 974, we get 2 with a remainder of 704.
Record the quotient 2 as the next digit in the result. 
Result so far: 8202.0
Subtract 1948 from 2652 to get 704.
Take the next digit (3) from the dividend and append it to 704, then repeat: 7043 / 974

Step 8:
When dividing 7043 by 974, we get 7 with a remainder of 225.
The number 7 becomes the next digit in our result. 
Result so far: 82027.0
Deduct 6818 from 7043 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 9:
2250 divided by 974 is 2 with a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 82027.2
If we subtract 1948 from 2250, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 10:
The number 974 fits into 3020 3 times, leaving a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 82027.23
The remainder is 98 after subtracting 2922 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 11:
If we divide 980 by 974, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 82027.231
Deduct 974 from 980 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
974 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 82027.231
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
The number 974 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 82027.231
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 82027.231 with a remainder of 0.0006.
