Let's divide 53347015 by 665
The aim is to understand the frequency of 665 in 53347015.

Advancing to step 1:
When dividing 5 by 665, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 665

Going ahead to step 2:
53 divided by 665 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 665

Let's proceed to step 3:
When dividing 533 by 665, we get 0 with a remainder of 533.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 533 leaves us with 533.
Bring next digit (4) of the dividend behind the 533 and repeat the process: 5334 / 665

Moving on to step 4:
The number 665 fits into 5334 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 14 after subtracting 5320 from 5334.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 665

Step 5:
147 divided by 665 is 0 with a remainder of 147.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 147 leaves us with 147.
Bring next digit (0) of the dividend behind the 147 and repeat the process: 1470 / 665

Moving on to step 6:
665 can be fit into 1470 2 times, resulting in a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 802.0
Deduct 1330 from 1470 and we're left with 140.
Grab the next digit (1) from the dividend, add it to 140, then carry on: 1401 / 665

Moving on to step 7:
665 goes into 1401 2 times with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 8022.0
The remainder is 71 after subtracting 1330 from 1401.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 665

Let's proceed to step 8:
If we divide 715 by 665, we get 1 and a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 80221.0
Subtract 665 from 715 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 665, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 80221.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 10:
The number 665 fits into 5000 7 times, leaving a remainder of 345.
Record the quotient 7 as the next digit in the result. 
Result so far: 80221.07
Deduct 4655 from 5000 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 11:
The number 665 fits into 3450 5 times, leaving a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 80221.075
If we subtract 3325 from 3450, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
If we divide 1250 by 665, we get 1 and a remainder of 585.
Write down 1 as next digit of the result. 
Result so far: 80221.0751
Subtract 665 from 1250 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 13:
665 goes into 5850 8 times with a remainder of 530.
The next digit of our result is 8. 
Result so far: 80221.07518
Subtracting 5320 from 5850 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 14:
When dividing 5300 by 665, we get 7 with a remainder of 645.
Record the quotient 7 as the next digit in the result. 
Result so far: 80221.075187
Deduct 4655 from 5300 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Going ahead to step 15:
665 goes into 6450 9 times with a remainder of 465.
Put 9 as the next digit of the answer. 
Result so far: 80221.0751879
Deduct 5985 from 6450 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 16:
665 goes into 4650 6 times with a remainder of 660.
The next digit of our result is 6. 
Result so far: 80221.07518796
If we subtract 3990 from 4650, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

After the division, we end up with 80221.07518796 and a remainder of 6.6e-07.
