We look at the division of 238425 by 76 
The aim is to understand the frequency of 76 in 238425.

On to step 1:
2 divided by 76 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 76

Moving on to step 2:
When dividing 23 by 76, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 76

On to step 3:
If we divide 238 by 76, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 228 from 238 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 76

On to step 4:
104 divided by 76 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 76 from 104 and we're left with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 76

On to step 5:
76 goes into 282 3 times with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 313.0
Deduct 228 from 282 and we're left with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 76

Moving on to step 6:
When dividing 545 by 76, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3137.0
If we take 532 away from 545, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 76 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 3137.1
If we take 76 away from 130, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
The number 76 fits into 540 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 3137.17
If we take 532 away from 540, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 76, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 3137.171
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 76, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3137.171
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 76, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3137.17105
Subtracting 380 from 400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
200 divided by 76 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 3137.171052
If we subtract 152 from 200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
When dividing 480 by 76, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 3137.1710526
Subtract 456 from 480 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
When dividing 240 by 76, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3137.17105263
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3137.17105263, and the remainder is 1.2e-08.
