55886975 divided by 443 
The aim is to understand the frequency of 443 in 55886975.

Let's proceed to step 1:
When dividing 5 by 443, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 443

Going ahead to step 2:
If we divide 55 by 443, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 443

Moving on to step 3:
The number 443 fits into 558 1 times, leaving a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 443 from 558, we get 115.
Bring next digit (8) of the dividend behind the 115 and repeat the process: 1158 / 443

On to step 4:
443 goes into 1158 2 times with a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 272 after subtracting 886 from 1158.
Include the next digit (6) from the dividend after 272, then repeat: 2726 / 443

On to step 5:
443 can be fit into 2726 6 times, resulting in a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 2658 away from 2726, we end up with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 443

Step 6:
443 goes into 689 1 times with a remainder of 246.
Write down 1 as next digit of the result. 
Result so far: 1261.0
Subtract 443 from 689 to get 246.
Include the next digit (7) from the dividend after 246, then repeat: 2467 / 443

On to step 7:
443 goes into 2467 5 times with a remainder of 252.
Record the quotient 5 as the next digit in the result. 
Result so far: 12615.0
If we take 2215 away from 2467, we end up with 252.
Grab the next digit (5) from the dividend, add it to 252, then carry on: 2525 / 443

Step 8:
443 goes into 2525 5 times with a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 126155.0
If we take 2215 away from 2525, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 9:
If we divide 3100 by 443, we get 6 and a remainder of 442.
The next digit of our result is 6. 
Result so far: 126155.6
The remainder is 442 after subtracting 2658 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
4420 divided by 443 is 9 with a remainder of 433.
Record the quotient 9 as the next digit in the result. 
Result so far: 126155.69
Subtracting 3987 from 4420 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 11:
When dividing 4330 by 443, we get 9 with a remainder of 343.
The number 9 becomes the next digit in our result. 
Result so far: 126155.699
Deduct 3987 from 4330 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final outcome is 126155.699, with a leftover of 0.0343.
