777210 ÷ 74 
The aim is to understand the frequency of 74 in 777210.

On to step 1:
74 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 74

Going ahead to step 2:
The number 74 fits into 77 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 74 away from 77, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 74

Advancing to step 3:
If we divide 37 by 74, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 74

Going ahead to step 4:
If we divide 372 by 74, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtracting 370 from 372 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 74

Let's proceed to step 5:
74 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 1050.0
If we subtract 0 from 21, we get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 74

On to step 6:
The number 74 fits into 210 2 times, leaving a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 10502.0
If we subtract 148 from 210, 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.

Step 7:
When dividing 620 by 74, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 10502.8
If we subtract 592 from 620, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
When dividing 280 by 74, we get 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 10502.83
If we take 222 away from 280, we end up 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.

Moving on to step 9:
74 goes into 580 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 10502.837
Deduct 518 from 580 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
74 can be fit into 620 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10502.8378
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.

On to step 11:
The number 74 fits into 280 3 times, leaving a remainder of 58.
The next digit of our result is 3. 
Result so far: 10502.83783
The remainder is 58 after subtracting 222 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
When dividing 580 by 74, we get 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 10502.837837
Subtracting 518 from 580 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
When dividing 620 by 74, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 10502.8378378
Subtract 592 from 620 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
74 goes into 280 3 times with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 10502.83783783
Subtracting 222 from 280 leaves us 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.

The final result is 10502.83783783 with a remainder of 5.8e-08.
