Let's divide 20457503 by 749
The aim is to understand the frequency of 749 in 20457503.

Advancing to step 1:
2 divided by 749 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 749

Let's proceed to step 2:
749 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 749

Moving on to step 3:
The number 749 fits into 204 0 times, leaving a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 204, we get 204.
Grab the next digit (5) from the dividend, add it to 204, then carry on: 2045 / 749

On to step 4:
2045 divided by 749 is 2 with a remainder of 547.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1498 from 2045 and we're left with 547.
Grab the next digit (7) from the dividend, add it to 547, then carry on: 5477 / 749

Advancing to step 5:
The number 749 fits into 5477 7 times, leaving a remainder of 234.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 5243 away from 5477, we end up with 234.
Append the next digit (5) from the dividend to 234 and continue with: 2345 / 749

Advancing to step 6:
2345 divided by 749 is 3 with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
Subtract 2247 from 2345 to get 98.
Append the next digit (0) from the dividend to 98 and continue with: 980 / 749

Moving on to step 7:
If we divide 980 by 749, we get 1 and a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 2731.0
If we subtract 749 from 980, we get 231.
Grab the next digit (3) from the dividend, add it to 231, then carry on: 2313 / 749

On to step 8:
2313 divided by 749 is 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 27313.0
Deduct 2247 from 2313 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
660 divided by 749 is 0 with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 27313.0
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 10:
749 goes into 6600 8 times with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 27313.08
The remainder is 608 after subtracting 5992 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 11:
6080 divided by 749 is 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 27313.088
If we take 5992 away from 6080, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 27313.088 with a remainder of 0.0088.
