We divide 21837700 by 662
The aim is to understand the frequency of 662 in 21837700.

On to step 1:
If we divide 2 by 662, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 662

On to step 2:
662 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 662

Let's proceed to step 3:
When dividing 218 by 662, we get 0 with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Include the next digit (3) from the dividend after 218, then repeat: 2183 / 662

Moving on to step 4:
662 can be fit into 2183 3 times, resulting in a remainder of 197.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1986 from 2183 to get 197.
Bring next digit (7) of the dividend behind the 197 and repeat the process: 1977 / 662

Advancing to step 5:
662 goes into 1977 2 times with a remainder of 653.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 1324 from 1977 leaves us with 653.
Append the next digit (7) from the dividend to 653 and continue with: 6537 / 662

On to step 6:
If we divide 6537 by 662, we get 9 and a remainder of 579.
Use 9 as the next digit of our solution. 
Result so far: 329.0
The remainder is 579 after subtracting 5958 from 6537.
Append the next digit (0) from the dividend to 579 and continue with: 5790 / 662

Let's proceed to step 7:
When dividing 5790 by 662, we get 8 with a remainder of 494.
The next digit of our result is 8. 
Result so far: 3298.0
If we subtract 5296 from 5790, we get 494.
Append the next digit (0) from the dividend to 494 and continue with: 4940 / 662

Going ahead to step 8:
4940 divided by 662 is 7 with a remainder of 306.
Put 7 as the next digit of the answer. 
Result so far: 32987.0
If we take 4634 away from 4940, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 9:
The number 662 fits into 3060 4 times, leaving a remainder of 412.
Record the quotient 4 as the next digit in the result. 
Result so far: 32987.4
If we take 2648 away from 3060, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 10:
662 can be fit into 4120 6 times, resulting in a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 32987.46
Deduct 3972 from 4120 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 11:
The number 662 fits into 1480 2 times, leaving a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 32987.462
Subtracting 1324 from 1480 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
662 goes into 1560 2 times with a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 32987.4622
Deduct 1324 from 1560 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 32987.4622, and the remainder is 0.00236.
