We're dividing 316221 by 74 
The aim is to understand the frequency of 74 in 316221.

Step 1:
74 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 74

Moving on to step 2:
If we divide 31 by 74, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 74

Advancing to step 3:
316 divided by 74 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 296 from 316 leaves us with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 74

Advancing to step 4:
When dividing 202 by 74, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 54 after subtracting 148 from 202.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 74

Moving on to step 5:
74 can be fit into 542 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 427.0
Subtract 518 from 542 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 74

Moving on to step 6:
The number 74 fits into 241 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 4273.0
The remainder is 19 after subtracting 222 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
74 goes into 190 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 4273.2
Subtract 148 from 190 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 74 fits into 420 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 4273.25
Subtract 370 from 420 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
If we divide 500 by 74, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 4273.256
If we subtract 444 from 500, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 74 is 7 with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 4273.2567
Subtracting 518 from 560 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
The number 74 fits into 420 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4273.25675
Subtracting 370 from 420 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
The number 74 fits into 500 6 times, leaving a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 4273.256756
Subtract 444 from 500 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
560 divided by 74 is 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 4273.2567567
The remainder is 42 after subtracting 518 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
The number 74 fits into 420 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 4273.25675675
If we take 370 away from 420, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 4273.25675675 with a remainder of 5e-08.
