We're dividing 62705234 by 645 
The aim is to understand the frequency of 645 in 62705234.

Moving on to step 1:
If we divide 6 by 645, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 645

Let's proceed to step 2:
62 divided by 645 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 645

Advancing to step 3:
If we divide 627 by 645, we get 0 and a remainder of 627.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 627, we end up with 627.
Take the next digit (0) from the dividend and append it to 627, then repeat: 6270 / 645

Moving on to step 4:
If we divide 6270 by 645, we get 9 and a remainder of 465.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 5805 from 6270 leaves us with 465.
Append the next digit (5) from the dividend to 465 and continue with: 4655 / 645

Moving on to step 5:
4655 divided by 645 is 7 with a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 4515 from 4655 and we're left with 140.
Take the next digit (2) from the dividend and append it to 140, then repeat: 1402 / 645

Going ahead to step 6:
If we divide 1402 by 645, we get 2 and a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 972.0
Subtract 1290 from 1402 to get 112.
Include the next digit (3) from the dividend after 112, then repeat: 1123 / 645

Going ahead to step 7:
1123 divided by 645 is 1 with a remainder of 478.
The number 1 becomes the next digit in our result. 
Result so far: 9721.0
Subtract 645 from 1123 to get 478.
Grab the next digit (4) from the dividend, add it to 478, then carry on: 4784 / 645

On to step 8:
If we divide 4784 by 645, we get 7 and a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 97217.0
If we take 4515 away from 4784, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 9:
645 can be fit into 2690 4 times, resulting in a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 97217.4
Subtracting 2580 from 2690 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
If we divide 1100 by 645, we get 1 and a remainder of 455.
Record the quotient 1 as the next digit in the result. 
Result so far: 97217.41
If we take 645 away from 1100, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 11:
When dividing 4550 by 645, we get 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 97217.417
Subtract 4515 from 4550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
350 divided by 645 is 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 97217.417
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 13:
645 can be fit into 3500 5 times, resulting in a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 97217.41705
If we subtract 3225 from 3500, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 14:
645 goes into 2750 4 times with a remainder of 170.
The next digit of our result is 4. 
Result so far: 97217.417054
If we take 2580 away from 2750, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
If we divide 1700 by 645, we get 2 and a remainder of 410.
Write down 2 as next digit of the result. 
Result so far: 97217.4170542
The remainder is 410 after subtracting 1290 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 16:
The number 645 fits into 4100 6 times, leaving a remainder of 230.
Use 6 as the next digit of our solution. 
Result so far: 97217.41705426
If we take 3870 away from 4100, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 97217.41705426, with a leftover of 2.3e-07.
