We look at the division of 76647457 by 447 
The aim is to understand the frequency of 447 in 76647457.

Going ahead to step 1:
The number 447 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 447

On to step 2:
The number 447 fits into 76 0 times, leaving a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 447

Advancing to step 3:
766 divided by 447 is 1 with a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 447 from 766 and we're left with 319.
Bring next digit (4) of the dividend behind the 319 and repeat the process: 3194 / 447

On to step 4:
3194 divided by 447 is 7 with a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 3129 from 3194 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 447

Let's proceed to step 5:
When dividing 657 by 447, we get 1 with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Deduct 447 from 657 and we're left with 210.
Bring next digit (4) of the dividend behind the 210 and repeat the process: 2104 / 447

Going ahead to step 6:
447 can be fit into 2104 4 times, resulting in a remainder of 316.
Write down 4 as next digit of the result. 
Result so far: 1714.0
Subtracting 1788 from 2104 leaves us with 316.
Take the next digit (5) from the dividend and append it to 316, then repeat: 3165 / 447

Step 7:
3165 divided by 447 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 17147.0
Subtract 3129 from 3165 to get 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 447

Let's proceed to step 8:
When dividing 367 by 447, we get 0 with a remainder of 367.
The next digit of our result is 0. 
Result so far: 171470.0
Subtract 0 from 367 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 9:
3670 divided by 447 is 8 with a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 171470.8
Subtract 3576 from 3670 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
If we divide 940 by 447, we get 2 and a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 171470.82
If we subtract 894 from 940, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
If we divide 460 by 447, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 171470.821
Deduct 447 from 460 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
447 can be fit into 130 0 times, resulting in a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 171470.821
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
447 can be fit into 1300 2 times, resulting in a remainder of 406.
Record the quotient 2 as the next digit in the result. 
Result so far: 171470.82102
Subtract 894 from 1300 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 14:
4060 divided by 447 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 171470.821029
Subtracting 4023 from 4060 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 15:
When dividing 370 by 447, we get 0 with a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 171470.821029
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 16:
If we divide 3700 by 447, we get 8 and a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 171470.82102908
If we take 3576 away from 3700, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 171470.82102908 and a remainder of 1.24e-07.
