21445577 ÷ 37 
The aim is to understand the frequency of 37 in 21445577.

Let's proceed to step 1:
37 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 37

Step 2:
When dividing 21 by 37, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 37

Advancing to step 3:
If we divide 214 by 37, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 185 away from 214, we end up with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 37

Going ahead to step 4:
37 goes into 294 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 259 from 294 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 37

Advancing to step 5:
37 can be fit into 355 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 579.0
Subtracting 333 from 355 leaves us with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 37

Moving on to step 6:
The number 37 fits into 225 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 5796.0
If we subtract 222 from 225, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 37

Moving on to step 7:
37 can be fit into 37 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 57961.0
The remainder is 0 after subtracting 37 from 37.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 37

Step 8:
If we divide 7 by 37, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 579610.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 37, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 579610.1
Deduct 37 from 70 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
37 can be fit into 330 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 579610.18
Subtract 296 from 330 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
The number 37 fits into 340 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 579610.189
Subtract 333 from 340 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
The number 37 fits into 70 1 times, leaving a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 579610.1891
If we subtract 37 from 70, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
The number 37 fits into 330 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 579610.18918
Subtracting 296 from 330 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
The number 37 fits into 340 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 579610.189189
If we take 333 away from 340, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 15:
The number 37 fits into 70 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 579610.1891891
Subtract 37 from 70 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 16:
When dividing 330 by 37, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 579610.18918918
Deduct 296 from 330 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 579610.18918918 with a balance of 3.4e-08.
