We're dividing 83910298 by 443 
The aim is to understand the frequency of 443 in 83910298.

Let's proceed to step 1:
443 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 443

Let's proceed to step 2:
443 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 443

On to step 3:
443 goes into 839 1 times with a remainder of 396.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 443 from 839, we get 396.
Append the next digit (1) from the dividend to 396 and continue with: 3961 / 443

Let's proceed to step 4:
443 can be fit into 3961 8 times, resulting in a remainder of 417.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 3544 from 3961 and we're left with 417.
Include the next digit (0) from the dividend after 417, then repeat: 4170 / 443

On to step 5:
4170 divided by 443 is 9 with a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtracting 3987 from 4170 leaves us with 183.
Grab the next digit (2) from the dividend, add it to 183, then carry on: 1832 / 443

Going ahead to step 6:
443 goes into 1832 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1894.0
If we subtract 1772 from 1832, we get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 443

On to step 7:
443 can be fit into 609 1 times, resulting in a remainder of 166.
Use 1 as the next digit of our solution. 
Result so far: 18941.0
If we subtract 443 from 609, we get 166.
Grab the next digit (8) from the dividend, add it to 166, then carry on: 1668 / 443

Let's proceed to step 8:
443 goes into 1668 3 times with a remainder of 339.
Use 3 as the next digit of our solution. 
Result so far: 189413.0
If we take 1329 away from 1668, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 9:
443 goes into 3390 7 times with a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 189413.7
The remainder is 289 after subtracting 3101 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 10:
If we divide 2890 by 443, we get 6 and a remainder of 232.
The next digit of our result is 6. 
Result so far: 189413.76
The remainder is 232 after subtracting 2658 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
If we divide 2320 by 443, we get 5 and a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 189413.765
The remainder is 105 after subtracting 2215 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
1050 divided by 443 is 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 189413.7652
The remainder is 164 after subtracting 886 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 13:
1640 divided by 443 is 3 with a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 189413.76523
Subtract 1329 from 1640 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 14:
443 can be fit into 3110 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 189413.765237
The remainder is 9 after subtracting 3101 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 15:
443 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 189413.765237
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 16:
If we divide 900 by 443, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 189413.76523702
The remainder is 14 after subtracting 886 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 189413.76523702 with a remainder of 1.4e-08.
