We look at the division of 39653521 by 662 
The aim is to understand the frequency of 662 in 39653521.

Step 1:
The number 662 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 662

Let's proceed to step 2:
39 divided by 662 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 662

Moving on to step 3:
662 goes into 396 0 times with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 396 after subtracting 0 from 396.
Grab the next digit (5) from the dividend, add it to 396, then carry on: 3965 / 662

Step 4:
If we divide 3965 by 662, we get 5 and a remainder of 655.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 655 after subtracting 3310 from 3965.
Bring next digit (3) of the dividend behind the 655 and repeat the process: 6553 / 662

Let's proceed to step 5:
When dividing 6553 by 662, we get 9 with a remainder of 595.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 5958 from 6553 and we're left with 595.
Include the next digit (5) from the dividend after 595, then repeat: 5955 / 662

Step 6:
The number 662 fits into 5955 8 times, leaving a remainder of 659.
Write down 8 as next digit of the result. 
Result so far: 598.0
The remainder is 659 after subtracting 5296 from 5955.
Grab the next digit (2) from the dividend, add it to 659, then carry on: 6592 / 662

Going ahead to step 7:
The number 662 fits into 6592 9 times, leaving a remainder of 634.
The next digit of our result is 9. 
Result so far: 5989.0
Deduct 5958 from 6592 and we're left with 634.
Include the next digit (1) from the dividend after 634, then repeat: 6341 / 662

On to step 8:
662 can be fit into 6341 9 times, resulting in a remainder of 383.
Record the quotient 9 as the next digit in the result. 
Result so far: 59899.0
Subtracting 5958 from 6341 leaves us with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 9:
3830 divided by 662 is 5 with a remainder of 520.
The number 5 becomes the next digit in our result. 
Result so far: 59899.5
If we take 3310 away from 3830, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 10:
662 can be fit into 5200 7 times, resulting in a remainder of 566.
Put 7 as the next digit of the answer. 
Result so far: 59899.57
Subtract 4634 from 5200 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 11:
5660 divided by 662 is 8 with a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 59899.578
Subtract 5296 from 5660 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 12:
662 can be fit into 3640 5 times, resulting in a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 59899.5785
Subtract 3310 from 3640 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 13:
662 can be fit into 3300 4 times, resulting in a remainder of 652.
Put 4 as the next digit of the answer. 
Result so far: 59899.57854
If we take 2648 away from 3300, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Step 14:
The number 662 fits into 6520 9 times, leaving a remainder of 562.
Record the quotient 9 as the next digit in the result. 
Result so far: 59899.578549
If we take 5958 away from 6520, we end up with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 15:
5620 divided by 662 is 8 with a remainder of 324.
The number 8 becomes the next digit in our result. 
Result so far: 59899.5785498
Deduct 5296 from 5620 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 16:
The number 662 fits into 3240 4 times, leaving a remainder of 592.
The number 4 becomes the next digit in our result. 
Result so far: 59899.57854984
Subtract 2648 from 3240 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final result is 59899.57854984 with a remainder of 5.92e-07.
