Let's divide 21587741 by 740
The aim is to understand the frequency of 740 in 21587741.

Let's proceed to step 1:
740 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 740

Step 2:
If we divide 21 by 740, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 740

Let's proceed to step 3:
740 can be fit into 215 0 times, resulting in a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Grab the next digit (8) from the dividend, add it to 215, then carry on: 2158 / 740

On to step 4:
2158 divided by 740 is 2 with a remainder of 678.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1480 from 2158 and we're left with 678.
Bring next digit (7) of the dividend behind the 678 and repeat the process: 6787 / 740

On to step 5:
740 can be fit into 6787 9 times, resulting in a remainder of 127.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 6660 from 6787 and we're left with 127.
Fetch the next digit (7) from the dividend, attach it to 127 and continue: 1277 / 740

Moving on to step 6:
740 goes into 1277 1 times with a remainder of 537.
The next digit of our result is 1. 
Result so far: 291.0
If we take 740 away from 1277, we end up with 537.
Take the next digit (4) from the dividend and append it to 537, then repeat: 5374 / 740

On to step 7:
740 goes into 5374 7 times with a remainder of 194.
Put 7 as the next digit of the answer. 
Result so far: 2917.0
If we subtract 5180 from 5374, we get 194.
Take the next digit (1) from the dividend and append it to 194, then repeat: 1941 / 740

Going ahead to step 8:
740 can be fit into 1941 2 times, resulting in a remainder of 461.
Put 2 as the next digit of the answer. 
Result so far: 29172.0
If we subtract 1480 from 1941, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 9:
4610 divided by 740 is 6 with a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 29172.6
The remainder is 170 after subtracting 4440 from 4610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
The number 740 fits into 1700 2 times, leaving a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 29172.62
Deduct 1480 from 1700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
If we divide 2200 by 740, we get 2 and a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 29172.622
Subtracting 1480 from 2200 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

After the division, we end up with 29172.622 and a remainder of 0.072.
