We look at the division of 162101 by 74 
The aim is to understand the frequency of 74 in 162101.

Going ahead to step 1:
If we divide 1 by 74, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 74

Moving on to step 2:
When dividing 16 by 74, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 74

On to step 3:
The number 74 fits into 162 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 148 away from 162, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 74

Let's proceed to step 4:
74 can be fit into 141 1 times, resulting in a remainder of 67.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 74 from 141, we get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 74

Moving on to step 5:
74 can be fit into 670 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Subtract 666 from 670 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 74

Going ahead to step 6:
If we divide 41 by 74, we get 0 and a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 2190.0
Subtract 0 from 41 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
410 divided by 74 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 2190.5
Subtract 370 from 410 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 74 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2190.55
If we take 370 away from 400, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 2190.55, and the remainder is 0.03.
