764038 ÷ 43 
The aim is to understand the frequency of 43 in 764038.

On to step 1:
When dividing 7 by 43, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 43

Going ahead to step 2:
If we divide 76 by 43, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 43 from 76 to get 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 43

On to step 3:
If we divide 334 by 43, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 301 from 334 to get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 43

Moving on to step 4:
If we divide 330 by 43, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 177.0
If we subtract 301 from 330, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 43

Step 5:
43 goes into 293 6 times with a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 1776.0
If we take 258 away from 293, we end up with 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 43

Going ahead to step 6:
43 goes into 358 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 17768.0
Subtract 344 from 358 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
43 goes into 140 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 17768.3
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
When dividing 110 by 43, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 17768.32
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
The number 43 fits into 240 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 17768.325
Subtract 215 from 240 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
43 can be fit into 250 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17768.3255
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 17768.3255, and the remainder is 0.00035.
