62947989 ÷ 525 
The aim is to understand the frequency of 525 in 62947989.

Step 1:
When dividing 6 by 525, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 525

Let's proceed to step 2:
If we divide 62 by 525, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 525

Let's proceed to step 3:
The number 525 fits into 629 1 times, leaving a remainder of 104.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 525 away from 629, we end up with 104.
Bring next digit (4) of the dividend behind the 104 and repeat the process: 1044 / 525

On to step 4:
The number 525 fits into 1044 1 times, leaving a remainder of 519.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 525 away from 1044, we end up with 519.
Fetch the next digit (7) from the dividend, attach it to 519 and continue: 5197 / 525

Moving on to step 5:
525 can be fit into 5197 9 times, resulting in a remainder of 472.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we subtract 4725 from 5197, we get 472.
Grab the next digit (9) from the dividend, add it to 472, then carry on: 4729 / 525

Advancing to step 6:
4729 divided by 525 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 1199.0
Subtract 4725 from 4729 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 525

Advancing to step 7:
48 divided by 525 is 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 11990.0
If we take 0 away from 48, we end up with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 525

Let's proceed to step 8:
525 can be fit into 489 0 times, resulting in a remainder of 489.
Use 0 as the next digit of our solution. 
Result so far: 119900.0
Subtract 0 from 489 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 9:
525 goes into 4890 9 times with a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 119900.9
Deduct 4725 from 4890 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 10:
The number 525 fits into 1650 3 times, leaving a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 119900.93
If we subtract 1575 from 1650, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
When dividing 750 by 525, we get 1 with a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 119900.931
The remainder is 225 after subtracting 525 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 12:
The number 525 fits into 2250 4 times, leaving a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 119900.9314
The remainder is 150 after subtracting 2100 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
1500 divided by 525 is 2 with a remainder of 450.
Put 2 as the next digit of the answer. 
Result so far: 119900.93142
If we subtract 1050 from 1500, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 14:
When dividing 4500 by 525, we get 8 with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 119900.931428
Subtract 4200 from 4500 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
When dividing 3000 by 525, we get 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 119900.9314285
Deduct 2625 from 3000 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 16:
525 can be fit into 3750 7 times, resulting in a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 119900.93142857
The remainder is 75 after subtracting 3675 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 119900.93142857, and the remainder is 7.5e-08.
