Let's divide 42664243 by 715
The aim is to understand the frequency of 715 in 42664243.

On to step 1:
When dividing 4 by 715, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 715

Step 2:
715 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 715

On to step 3:
715 can be fit into 426 0 times, resulting in a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 426, we get 426.
Take the next digit (6) from the dividend and append it to 426, then repeat: 4266 / 715

Step 4:
715 goes into 4266 5 times with a remainder of 691.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 3575 away from 4266, we end up with 691.
Append the next digit (4) from the dividend to 691 and continue with: 6914 / 715

Moving on to step 5:
When dividing 6914 by 715, we get 9 with a remainder of 479.
The next digit of our result is 9. 
Result so far: 59.0
If we take 6435 away from 6914, we end up with 479.
Grab the next digit (2) from the dividend, add it to 479, then carry on: 4792 / 715

Moving on to step 6:
If we divide 4792 by 715, we get 6 and a remainder of 502.
Put 6 as the next digit of the answer. 
Result so far: 596.0
Deduct 4290 from 4792 and we're left with 502.
Fetch the next digit (4) from the dividend, attach it to 502 and continue: 5024 / 715

Step 7:
When dividing 5024 by 715, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 5967.0
Deduct 5005 from 5024 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 715

Step 8:
If we divide 193 by 715, we get 0 and a remainder of 193.
Put 0 as the next digit of the answer. 
Result so far: 59670.0
Deduct 0 from 193 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 9:
The number 715 fits into 1930 2 times, leaving a remainder of 500.
Write down 2 as next digit of the result. 
Result so far: 59670.2
The remainder is 500 after subtracting 1430 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
When dividing 5000 by 715, we get 6 with a remainder of 710.
Record the quotient 6 as the next digit in the result. 
Result so far: 59670.26
Subtract 4290 from 5000 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 11:
If we divide 7100 by 715, we get 9 and a remainder of 665.
Write down 9 as next digit of the result. 
Result so far: 59670.269
Deduct 6435 from 7100 and we're left with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 12:
6650 divided by 715 is 9 with a remainder of 215.
The next digit of our result is 9. 
Result so far: 59670.2699
The remainder is 215 after subtracting 6435 from 6650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final outcome is 59670.2699, with a leftover of 0.00215.
