20412985 ÷ 756 
The aim is to understand the frequency of 756 in 20412985.

On to step 1:
2 divided by 756 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 756

Step 2:
When dividing 20 by 756, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 756

Moving on to step 3:
The number 756 fits into 204 0 times, leaving a remainder of 204.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 204, we get 204.
Append the next digit (1) from the dividend to 204 and continue with: 2041 / 756

Let's proceed to step 4:
The number 756 fits into 2041 2 times, leaving a remainder of 529.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1512 from 2041 to get 529.
Bring next digit (2) of the dividend behind the 529 and repeat the process: 5292 / 756

Advancing to step 5:
756 goes into 5292 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 5292 from 5292 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 756

Step 6:
The number 756 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 756

On to step 7:
756 can be fit into 98 0 times, resulting in a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 2700.0
If we subtract 0 from 98, we get 98.
Fetch the next digit (5) from the dividend, attach it to 98 and continue: 985 / 756

Step 8:
756 goes into 985 1 times with a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 27001.0
Subtracting 756 from 985 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 9:
The number 756 fits into 2290 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 27001.3
If we subtract 2268 from 2290, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
756 can be fit into 220 0 times, resulting in a remainder of 220.
The next digit of our result is 0. 
Result so far: 27001.3
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
756 can be fit into 2200 2 times, resulting in a remainder of 688.
The number 2 becomes the next digit in our result. 
Result so far: 27001.302
If we take 1512 away from 2200, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 12:
If we divide 6880 by 756, we get 9 and a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 27001.3029
Subtract 6804 from 6880 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
760 divided by 756 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 27001.30291
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 756 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 27001.30291
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
If we divide 400 by 756, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 27001.30291
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 27001.30291 with a remainder of 4e-06.
