43642985 ÷ 715 
The aim is to understand the frequency of 715 in 43642985.

Moving on to step 1:
715 can be fit into 4 0 times, resulting in 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.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 715

Going ahead to step 2:
If we divide 43 by 715, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 715

Advancing to step 3:
436 divided by 715 is 0 with a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 436 and we're left with 436.
Fetch the next digit (4) from the dividend, attach it to 436 and continue: 4364 / 715

Let's proceed to step 4:
4364 divided by 715 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 74 after subtracting 4290 from 4364.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 715

Going ahead to step 5:
715 can be fit into 742 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtract 715 from 742 to get 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 715

Advancing to step 6:
When dividing 279 by 715, we get 0 with a remainder of 279.
Put 0 as the next digit of the answer. 
Result so far: 610.0
If we subtract 0 from 279, we get 279.
Fetch the next digit (8) from the dividend, attach it to 279 and continue: 2798 / 715

Going ahead to step 7:
The number 715 fits into 2798 3 times, leaving a remainder of 653.
Record the quotient 3 as the next digit in the result. 
Result so far: 6103.0
Subtracting 2145 from 2798 leaves us with 653.
Bring next digit (5) of the dividend behind the 653 and repeat the process: 6535 / 715

Going ahead to step 8:
If we divide 6535 by 715, we get 9 and a remainder of 100.
The next digit of our result is 9. 
Result so far: 61039.0
The remainder is 100 after subtracting 6435 from 6535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 9:
1000 divided by 715 is 1 with a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 61039.1
Deduct 715 from 1000 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 10:
2850 divided by 715 is 3 with a remainder of 705.
Record the quotient 3 as the next digit in the result. 
Result so far: 61039.13
Deduct 2145 from 2850 and we're left with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Moving on to step 11:
7050 divided by 715 is 9 with a remainder of 615.
Put 9 as the next digit of the answer. 
Result so far: 61039.139
If we take 6435 away from 7050, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 12:
715 can be fit into 6150 8 times, resulting in a remainder of 430.
The number 8 becomes the next digit in our result. 
Result so far: 61039.1398
Subtracting 5720 from 6150 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 13:
715 can be fit into 4300 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 61039.13986
Subtract 4290 from 4300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 715 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 61039.13986
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
The number 715 fits into 1000 1 times, leaving a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 61039.1398601
Subtracting 715 from 1000 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 16:
2850 divided by 715 is 3 with a remainder of 705.
Use 3 as the next digit of our solution. 
Result so far: 61039.13986013
Subtracting 2145 from 2850 leaves us with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

The final outcome is 61039.13986013, with a leftover of 7.05e-07.
