80391117 ÷ 447 
The aim is to understand the frequency of 447 in 80391117.

Advancing to step 1:
If we divide 8 by 447, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 447

Step 2:
If we divide 80 by 447, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 447

On to step 3:
447 can be fit into 803 1 times, resulting in a remainder of 356.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 447 away from 803, we end up with 356.
Grab the next digit (9) from the dividend, add it to 356, then carry on: 3569 / 447

Advancing to step 4:
3569 divided by 447 is 7 with a remainder of 440.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 440 after subtracting 3129 from 3569.
Append the next digit (1) from the dividend to 440 and continue with: 4401 / 447

Let's proceed to step 5:
When dividing 4401 by 447, we get 9 with a remainder of 378.
Use 9 as the next digit of our solution. 
Result so far: 179.0
If we subtract 4023 from 4401, we get 378.
Take the next digit (1) from the dividend and append it to 378, then repeat: 3781 / 447

Step 6:
When dividing 3781 by 447, we get 8 with a remainder of 205.
Use 8 as the next digit of our solution. 
Result so far: 1798.0
Subtract 3576 from 3781 to get 205.
Take the next digit (1) from the dividend and append it to 205, then repeat: 2051 / 447

Advancing to step 7:
447 goes into 2051 4 times with a remainder of 263.
The next digit of our result is 4. 
Result so far: 17984.0
Deduct 1788 from 2051 and we're left with 263.
Append the next digit (7) from the dividend to 263 and continue with: 2637 / 447

Going ahead to step 8:
The number 447 fits into 2637 5 times, leaving a remainder of 402.
Write down 5 as next digit of the result. 
Result so far: 179845.0
The remainder is 402 after subtracting 2235 from 2637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 9:
447 goes into 4020 8 times with a remainder of 444.
The next digit of our result is 8. 
Result so far: 179845.8
Subtracting 3576 from 4020 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 10:
447 goes into 4440 9 times with a remainder of 417.
Put 9 as the next digit of the answer. 
Result so far: 179845.89
If we take 4023 away from 4440, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 11:
4170 divided by 447 is 9 with a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 179845.899
The remainder is 147 after subtracting 4023 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Our division results in 179845.899 with a remaining 0.0147.
