377068 ÷ 75 
The aim is to understand the frequency of 75 in 377068.

Step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 75

On to step 2:
If we divide 37 by 75, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 75

Advancing to step 3:
If we divide 377 by 75, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 375 from 377, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 75

Advancing to step 4:
75 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 20, we get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 75

Let's proceed to step 5:
The number 75 fits into 206 2 times, leaving a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 502.0
If we take 150 away from 206, we end up with 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 75

Advancing to step 6:
75 can be fit into 568 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 5027.0
If we take 525 away from 568, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
When dividing 430 by 75, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 5027.5
If we take 375 away from 430, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
The number 75 fits into 550 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 5027.57
Deduct 525 from 550 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 5027.573
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The next digit of our result is 3. 
Result so far: 5027.5733
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 5027.5733 with a remaining 0.00025.
