We're dividing 155431 by 76 
The aim is to understand the frequency of 76 in 155431.

Let's proceed to step 1:
1 divided by 76 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 76

Step 2:
When dividing 15 by 76, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 76

Advancing to step 3:
155 divided by 76 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 3 after subtracting 152 from 155.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 76

Advancing to step 4:
34 divided by 76 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 34, we end up with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 76

Moving on to step 5:
When dividing 343 by 76, we get 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 204.0
If we take 304 away from 343, we end up with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 76

On to step 6:
When dividing 391 by 76, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 2045.0
The remainder is 11 after subtracting 380 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
The number 76 fits into 110 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 2045.1
If we take 76 away from 110, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
The number 76 fits into 340 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 2045.14
If we subtract 304 from 340, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
360 divided by 76 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 2045.144
Deduct 304 from 360 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 2045.144 and a remainder of 0.0056.
