We're dividing 878793 by 43 
The aim is to understand the frequency of 43 in 878793.

Step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 43

Step 2:
43 can be fit into 87 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 86 away from 87, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 43

On to step 3:
If we divide 18 by 43, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 43

Advancing to step 4:
43 can be fit into 187 4 times, resulting in a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Subtracting 172 from 187 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 43

On to step 5:
43 goes into 159 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2043.0
If we take 129 away from 159, we end up with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 43

On to step 6:
43 can be fit into 303 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 20437.0
Deduct 301 from 303 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 43 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 20437.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 43, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 20437.04
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
43 can be fit into 280 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 20437.046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
When dividing 220 by 43, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 20437.0465
Subtracting 215 from 220 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
If we divide 50 by 43, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 20437.04651
If we subtract 43 from 50, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
43 can be fit into 70 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 20437.046511
If we take 43 away from 70, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 20437.046511 with a balance of 2.7e-06.
