We divide 20988737 by 674
The aim is to understand the frequency of 674 in 20988737.

Step 1:
674 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 674

Advancing to step 2:
674 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 674

Advancing to step 3:
674 can be fit into 209 0 times, resulting in a remainder of 209.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 209 to get 209.
Include the next digit (8) from the dividend after 209, then repeat: 2098 / 674

Going ahead to step 4:
2098 divided by 674 is 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 76 after subtracting 2022 from 2098.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 674

Going ahead to step 5:
If we divide 768 by 674, we get 1 and a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 674 from 768 to get 94.
Grab the next digit (7) from the dividend, add it to 94, then carry on: 947 / 674

On to step 6:
674 goes into 947 1 times with a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 311.0
The remainder is 273 after subtracting 674 from 947.
Take the next digit (3) from the dividend and append it to 273, then repeat: 2733 / 674

Let's proceed to step 7:
674 goes into 2733 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 3114.0
Subtract 2696 from 2733 to get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 674

On to step 8:
377 divided by 674 is 0 with a remainder of 377.
Record the quotient 0 as the next digit in the result. 
Result so far: 31140.0
The remainder is 377 after subtracting 0 from 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Step 9:
The number 674 fits into 3770 5 times, leaving a remainder of 400.
The next digit of our result is 5. 
Result so far: 31140.5
Deduct 3370 from 3770 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
The number 674 fits into 4000 5 times, leaving a remainder of 630.
Record the quotient 5 as the next digit in the result. 
Result so far: 31140.55
If we subtract 3370 from 4000, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The final outcome is 31140.55, with a leftover of 0.63.
