Let's divide 76212548 by 843
The aim is to understand the frequency of 843 in 76212548.

Moving on to step 1:
When dividing 7 by 843, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 843

Moving on to step 2:
When dividing 76 by 843, we get 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 843

Going ahead to step 3:
843 can be fit into 762 0 times, resulting in a remainder of 762.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 762 after subtracting 0 from 762.
Fetch the next digit (1) from the dividend, attach it to 762 and continue: 7621 / 843

On to step 4:
843 goes into 7621 9 times with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7587 from 7621 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 843

Advancing to step 5:
342 divided by 843 is 0 with a remainder of 342.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 342 and we're left with 342.
Bring next digit (5) of the dividend behind the 342 and repeat the process: 3425 / 843

Going ahead to step 6:
843 can be fit into 3425 4 times, resulting in a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 904.0
Subtract 3372 from 3425 to get 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 843

Going ahead to step 7:
The number 843 fits into 534 0 times, leaving a remainder of 534.
Record the quotient 0 as the next digit in the result. 
Result so far: 9040.0
If we take 0 away from 534, we end up with 534.
Take the next digit (8) from the dividend and append it to 534, then repeat: 5348 / 843

Advancing to step 8:
The number 843 fits into 5348 6 times, leaving a remainder of 290.
Use 6 as the next digit of our solution. 
Result so far: 90406.0
Subtract 5058 from 5348 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
843 can be fit into 2900 3 times, resulting in a remainder of 371.
Use 3 as the next digit of our solution. 
Result so far: 90406.3
Deduct 2529 from 2900 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 10:
The number 843 fits into 3710 4 times, leaving a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 90406.34
Deduct 3372 from 3710 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 11:
When dividing 3380 by 843, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 90406.344
Subtracting 3372 from 3380 leaves us 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.

The quotient of the division is 90406.344, and the remainder is 0.0008.
