764374 divided by 76 
The aim is to understand the frequency of 76 in 764374.

Step 1:
The number 76 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 76

Going ahead to step 2:
If we divide 76 by 76, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 76 from 76 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 76

Let's proceed to step 3:
When dividing 4 by 76, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 76

Advancing to step 4:
76 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 76

Advancing to step 5:
437 divided by 76 is 5 with a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 1005.0
If we take 380 away from 437, we end up with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 76

On to step 6:
The number 76 fits into 574 7 times, leaving a remainder of 42.
The next digit of our result is 7. 
Result so far: 10057.0
If we take 532 away from 574, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
76 can be fit into 420 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 10057.5
If we take 380 away from 420, we end up 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.

On to step 8:
76 can be fit into 400 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10057.55
Subtract 380 from 400 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 10057.55, with a leftover of 0.02.
