85506879 ÷ 43 
The aim is to understand the frequency of 43 in 85506879.

Moving on to step 1:
8 divided by 43 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 43

Moving on to step 2:
When dividing 85 by 43, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 43 from 85 and we're left with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 43

Moving on to step 3:
If we divide 425 by 43, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 387 from 425 to get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 43

Going ahead to step 4:
The number 43 fits into 380 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
The remainder is 36 after subtracting 344 from 380.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 43

Going ahead to step 5:
366 divided by 43 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 1988.0
If we subtract 344 from 366, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 43

Advancing to step 6:
The number 43 fits into 228 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 19885.0
If we subtract 215 from 228, we get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 43

Moving on to step 7:
137 divided by 43 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 198853.0
If we subtract 129 from 137, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 43

Moving on to step 8:
If we divide 89 by 43, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1988532.0
If we take 86 away from 89, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
If we divide 30 by 43, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1988532.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 1988532.06
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
If we divide 420 by 43, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1988532.069
If we take 387 away from 420, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
If we divide 330 by 43, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1988532.0697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
When dividing 290 by 43, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 1988532.06976
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
43 goes into 320 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 1988532.069767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 15:
The number 43 fits into 190 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1988532.0697674
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 16:
180 divided by 43 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1988532.06976744
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 1988532.06976744, and the remainder is 8e-09.
