We look at the division of 51600494 by 447 
The aim is to understand the frequency of 447 in 51600494.

Step 1:
When dividing 5 by 447, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 447

On to step 2:
447 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 447

Advancing to step 3:
447 can be fit into 516 1 times, resulting in a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 447 from 516 leaves us with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 447

Let's proceed to step 4:
When dividing 690 by 447, we get 1 with a remainder of 243.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 447 from 690 leaves us with 243.
Grab the next digit (0) from the dividend, add it to 243, then carry on: 2430 / 447

Step 5:
When dividing 2430 by 447, we get 5 with a remainder of 195.
The next digit of our result is 5. 
Result so far: 115.0
Subtracting 2235 from 2430 leaves us with 195.
Append the next digit (4) from the dividend to 195 and continue with: 1954 / 447

Going ahead to step 6:
447 goes into 1954 4 times with a remainder of 166.
The number 4 becomes the next digit in our result. 
Result so far: 1154.0
Deduct 1788 from 1954 and we're left with 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 447

Going ahead to step 7:
1669 divided by 447 is 3 with a remainder of 328.
The next digit of our result is 3. 
Result so far: 11543.0
If we take 1341 away from 1669, we end up with 328.
Grab the next digit (4) from the dividend, add it to 328, then carry on: 3284 / 447

Step 8:
When dividing 3284 by 447, we get 7 with a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 115437.0
Deduct 3129 from 3284 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 9:
447 goes into 1550 3 times with a remainder of 209.
Write down 3 as next digit of the result. 
Result so far: 115437.3
Deduct 1341 from 1550 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 10:
When dividing 2090 by 447, we get 4 with a remainder of 302.
The next digit of our result is 4. 
Result so far: 115437.34
Subtracting 1788 from 2090 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 11:
If we divide 3020 by 447, we get 6 and a remainder of 338.
Put 6 as the next digit of the answer. 
Result so far: 115437.346
The remainder is 338 after subtracting 2682 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 12:
3380 divided by 447 is 7 with a remainder of 251.
Write down 7 as next digit of the result. 
Result so far: 115437.3467
Subtracting 3129 from 3380 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 13:
When dividing 2510 by 447, we get 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 115437.34675
The remainder is 275 after subtracting 2235 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 14:
2750 divided by 447 is 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 115437.346756
If we subtract 2682 from 2750, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 15:
The number 447 fits into 680 1 times, leaving a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 115437.3467561
If we subtract 447 from 680, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 16:
2330 divided by 447 is 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 115437.34675615
Subtracting 2235 from 2330 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final outcome is 115437.34675615, with a leftover of 9.5e-08.
