We look at the division of 51472780 by 443 
The aim is to understand the frequency of 443 in 51472780.

Step 1:
443 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 443

Moving on to step 2:
If we divide 51 by 443, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 443

On to step 3:
443 goes into 514 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 443 from 514 to get 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 443

Let's proceed to step 4:
717 divided by 443 is 1 with a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 443 from 717 leaves us with 274.
Take the next digit (2) from the dividend and append it to 274, then repeat: 2742 / 443

On to step 5:
2742 divided by 443 is 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 116.0
Deduct 2658 from 2742 and we're left with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 443

On to step 6:
847 divided by 443 is 1 with a remainder of 404.
Record the quotient 1 as the next digit in the result. 
Result so far: 1161.0
Subtracting 443 from 847 leaves us with 404.
Bring next digit (8) of the dividend behind the 404 and repeat the process: 4048 / 443

Going ahead to step 7:
When dividing 4048 by 443, we get 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 11619.0
Deduct 3987 from 4048 and we're left with 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 443

Let's proceed to step 8:
443 goes into 610 1 times with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 116191.0
If we subtract 443 from 610, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 9:
443 can be fit into 1670 3 times, resulting in a remainder of 341.
Record the quotient 3 as the next digit in the result. 
Result so far: 116191.3
Subtracting 1329 from 1670 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 10:
If we divide 3410 by 443, we get 7 and a remainder of 309.
Write down 7 as next digit of the result. 
Result so far: 116191.37
Deduct 3101 from 3410 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 11:
443 can be fit into 3090 6 times, resulting in a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 116191.376
Deduct 2658 from 3090 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
When dividing 4320 by 443, we get 9 with a remainder of 333.
Put 9 as the next digit of the answer. 
Result so far: 116191.3769
Deduct 3987 from 4320 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 13:
443 can be fit into 3330 7 times, resulting in a remainder of 229.
Record the quotient 7 as the next digit in the result. 
Result so far: 116191.37697
The remainder is 229 after subtracting 3101 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 14:
The number 443 fits into 2290 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 116191.376975
If we take 2215 away from 2290, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 15:
When dividing 750 by 443, we get 1 with a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 116191.3769751
The remainder is 307 after subtracting 443 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 16:
443 can be fit into 3070 6 times, resulting in a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 116191.37697516
If we take 2658 away from 3070, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

The final outcome is 116191.37697516, with a leftover of 4.12e-07.
