We look at the division of 714091 by 74 
The aim is to understand the frequency of 74 in 714091.

Step 1:
If we divide 7 by 74, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 74

Moving on to step 2:
When dividing 71 by 74, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 74

Let's proceed to step 3:
The number 74 fits into 714 9 times, leaving a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 666 from 714 to get 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 74

Moving on to step 4:
When dividing 480 by 74, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 444 away from 480, we end up with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 74

Let's proceed to step 5:
If we divide 369 by 74, we get 4 and a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 964.0
Deduct 296 from 369 and we're left with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 74

Step 6:
When dividing 731 by 74, we get 9 with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 9649.0
If we subtract 666 from 731, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
When dividing 650 by 74, we get 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 9649.8
The remainder is 58 after subtracting 592 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
The number 74 fits into 580 7 times, leaving a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 9649.87
The remainder is 62 after subtracting 518 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
When dividing 620 by 74, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 9649.878
The remainder is 28 after subtracting 592 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
The number 74 fits into 280 3 times, leaving a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 9649.8783
Deduct 222 from 280 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
580 divided by 74 is 7 with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 9649.87837
If we subtract 518 from 580, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
74 goes into 620 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 9649.878378
Deduct 592 from 620 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 74 is 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 9649.8783783
If we subtract 222 from 280, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
The number 74 fits into 580 7 times, leaving a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 9649.87837837
If we subtract 518 from 580, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 9649.87837837 with a remainder of 6.2e-08.
