Let's divide 80744723 by 481
The aim is to understand the frequency of 481 in 80744723.

On to step 1:
If we divide 8 by 481, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 481

Going ahead to step 2:
The number 481 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 481

Going ahead to step 3:
807 divided by 481 is 1 with a remainder of 326.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 481 from 807 and we're left with 326.
Take the next digit (4) from the dividend and append it to 326, then repeat: 3264 / 481

Moving on to step 4:
481 goes into 3264 6 times with a remainder of 378.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 2886 from 3264 and we're left with 378.
Grab the next digit (4) from the dividend, add it to 378, then carry on: 3784 / 481

Let's proceed to step 5:
The number 481 fits into 3784 7 times, leaving a remainder of 417.
The next digit of our result is 7. 
Result so far: 167.0
If we take 3367 away from 3784, we end up with 417.
Include the next digit (7) from the dividend after 417, then repeat: 4177 / 481

Going ahead to step 6:
4177 divided by 481 is 8 with a remainder of 329.
Write down 8 as next digit of the result. 
Result so far: 1678.0
Subtract 3848 from 4177 to get 329.
Grab the next digit (2) from the dividend, add it to 329, then carry on: 3292 / 481

On to step 7:
The number 481 fits into 3292 6 times, leaving a remainder of 406.
Record the quotient 6 as the next digit in the result. 
Result so far: 16786.0
The remainder is 406 after subtracting 2886 from 3292.
Append the next digit (3) from the dividend to 406 and continue with: 4063 / 481

Let's proceed to step 8:
The number 481 fits into 4063 8 times, leaving a remainder of 215.
Put 8 as the next digit of the answer. 
Result so far: 167868.0
Subtract 3848 from 4063 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 9:
When dividing 2150 by 481, we get 4 with a remainder of 226.
The next digit of our result is 4. 
Result so far: 167868.4
Subtract 1924 from 2150 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
481 goes into 2260 4 times with a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 167868.44
If we take 1924 away from 2260, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The quotient of the division is 167868.44, and the remainder is 0.336.
