We're dividing 78864988 by 443 
The aim is to understand the frequency of 443 in 78864988.

Advancing to step 1:
When dividing 7 by 443, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 443

Advancing to step 2:
If we divide 78 by 443, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 443

Let's proceed to step 3:
If we divide 788 by 443, we get 1 and a remainder of 345.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 443 from 788, we get 345.
Include the next digit (6) from the dividend after 345, then repeat: 3456 / 443

Let's proceed to step 4:
If we divide 3456 by 443, we get 7 and a remainder of 355.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3101 away from 3456, we end up with 355.
Take the next digit (4) from the dividend and append it to 355, then repeat: 3554 / 443

Let's proceed to step 5:
3554 divided by 443 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 10 after subtracting 3544 from 3554.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 443

Moving on to step 6:
When dividing 109 by 443, we get 0 with a remainder of 109.
The next digit of our result is 0. 
Result so far: 1780.0
Subtract 0 from 109 to get 109.
Fetch the next digit (8) from the dividend, attach it to 109 and continue: 1098 / 443

Let's proceed to step 7:
443 goes into 1098 2 times with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 17802.0
Subtracting 886 from 1098 leaves us with 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 443

Going ahead to step 8:
The number 443 fits into 2128 4 times, leaving a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 178024.0
Deduct 1772 from 2128 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 9:
When dividing 3560 by 443, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 178024.8
If we subtract 3544 from 3560, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
443 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 178024.8
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
443 goes into 1600 3 times with a remainder of 271.
Record the quotient 3 as the next digit in the result. 
Result so far: 178024.803
Deduct 1329 from 1600 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 12:
2710 divided by 443 is 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 178024.8036
If we take 2658 away from 2710, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
When dividing 520 by 443, we get 1 with a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 178024.80361
If we take 443 away from 520, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
443 goes into 770 1 times with a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 178024.803611
Deduct 443 from 770 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The final outcome is 178024.803611, with a leftover of 3.27e-05.
