81553092 divided by 76 
The aim is to understand the frequency of 76 in 81553092.

On to step 1:
8 divided by 76 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 76

Going ahead to step 2:
When dividing 81 by 76, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 76 away from 81, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 76

Moving on to step 3:
76 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 76

Moving on to step 4:
When dividing 555 by 76, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 532 away from 555, we end up with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 76

Step 5:
76 can be fit into 233 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1073.0
If we subtract 228 from 233, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 76

Step 6:
When dividing 50 by 76, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10730.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 76

On to step 7:
509 divided by 76 is 6 with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 107306.0
Subtracting 456 from 509 leaves us with 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 76

Let's proceed to step 8:
76 goes into 532 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1073067.0
Subtracting 532 from 532 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
76 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1073067.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 76, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1073067.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 1073067.0, and the remainder is 0.0.
