We look at the division of 16090 by 76 
The aim is to understand the frequency of 76 in 16090.

Step 1:
If we divide 1 by 76, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 76

Moving on to step 2:
When dividing 16 by 76, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 76

Advancing to step 3:
If we divide 160 by 76, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 152 away from 160, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 76

On to step 4:
76 can be fit into 89 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 76 from 89 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 76

Moving on to step 5:
130 divided by 76 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 211.0
Subtracting 76 from 130 leaves us 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.

Advancing to step 6:
If we divide 540 by 76, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 211.7
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.

Moving on to step 7:
When dividing 80 by 76, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 211.71
Subtracting 76 from 80 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
76 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 211.71
Deduct 0 from 40 and we're left 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 9:
76 goes into 400 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 211.7105
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.

Moving on to step 10:
When dividing 200 by 76, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 211.71052
The remainder is 48 after subtracting 152 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 76, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 211.710526
If we subtract 456 from 480, we 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.

Step 12:
240 divided by 76 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 211.7105263
Deduct 228 from 240 and we're left 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.

Advancing to step 13:
76 goes into 120 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 211.71052631
If we subtract 76 from 120, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 211.71052631, and the remainder is 4.4e-08.
