Let's divide 26838641 by 570
The aim is to understand the frequency of 570 in 26838641.

On to step 1:
570 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 570

Step 2:
26 divided by 570 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 570

Moving on to step 3:
If we divide 268 by 570, we get 0 and a remainder of 268.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 268, we end up with 268.
Grab the next digit (3) from the dividend, add it to 268, then carry on: 2683 / 570

Going ahead to step 4:
2683 divided by 570 is 4 with a remainder of 403.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2280 from 2683 to get 403.
Fetch the next digit (8) from the dividend, attach it to 403 and continue: 4038 / 570

Advancing to step 5:
570 can be fit into 4038 7 times, resulting in a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 3990 away from 4038, we end up with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 570

On to step 6:
If we divide 486 by 570, we get 0 and a remainder of 486.
Write down 0 as next digit of the result. 
Result so far: 470.0
Deduct 0 from 486 and we're left with 486.
Fetch the next digit (4) from the dividend, attach it to 486 and continue: 4864 / 570

Advancing to step 7:
If we divide 4864 by 570, we get 8 and a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 4708.0
Subtracting 4560 from 4864 leaves us with 304.
Fetch the next digit (1) from the dividend, attach it to 304 and continue: 3041 / 570

Step 8:
3041 divided by 570 is 5 with a remainder of 191.
Put 5 as the next digit of the answer. 
Result so far: 47085.0
Subtracting 2850 from 3041 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 9:
570 can be fit into 1910 3 times, resulting in a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 47085.3
If we take 1710 away from 1910, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
If we divide 2000 by 570, we get 3 and a remainder of 290.
Write down 3 as next digit of the result. 
Result so far: 47085.33
Deduct 1710 from 2000 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 47085.33 and a remainder of 0.29.
