Let's divide 72241637 by 899
The aim is to understand the frequency of 899 in 72241637.

Step 1:
The number 899 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 899

On to step 2:
899 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 899

Advancing to step 3:
The number 899 fits into 722 0 times, leaving a remainder of 722.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 722 leaves us with 722.
Fetch the next digit (4) from the dividend, attach it to 722 and continue: 7224 / 899

On to step 4:
If we divide 7224 by 899, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 32 after subtracting 7192 from 7224.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 899

Going ahead to step 5:
899 can be fit into 321 0 times, resulting in a remainder of 321.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 321 after subtracting 0 from 321.
Fetch the next digit (6) from the dividend, attach it to 321 and continue: 3216 / 899

Moving on to step 6:
3216 divided by 899 is 3 with a remainder of 519.
Record the quotient 3 as the next digit in the result. 
Result so far: 803.0
If we take 2697 away from 3216, we end up with 519.
Grab the next digit (3) from the dividend, add it to 519, then carry on: 5193 / 899

Step 7:
899 goes into 5193 5 times with a remainder of 698.
Record the quotient 5 as the next digit in the result. 
Result so far: 8035.0
If we take 4495 away from 5193, we end up with 698.
Take the next digit (7) from the dividend and append it to 698, then repeat: 6987 / 899

On to step 8:
If we divide 6987 by 899, we get 7 and a remainder of 694.
Put 7 as the next digit of the answer. 
Result so far: 80357.0
Subtracting 6293 from 6987 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Step 9:
If we divide 6940 by 899, we get 7 and a remainder of 647.
The next digit of our result is 7. 
Result so far: 80357.7
If we take 6293 away from 6940, we end up with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Advancing to step 10:
When dividing 6470 by 899, we get 7 with a remainder of 177.
The next digit of our result is 7. 
Result so far: 80357.77
If we subtract 6293 from 6470, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The final outcome is 80357.77, with a leftover of 0.177.
