63415739 ÷ 709 
The aim is to understand the frequency of 709 in 63415739.

Let's proceed to step 1:
The number 709 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 709

Step 2:
If we divide 63 by 709, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 709

Step 3:
709 can be fit into 634 0 times, resulting in a remainder of 634.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 634 to get 634.
Include the next digit (1) from the dividend after 634, then repeat: 6341 / 709

Advancing to step 4:
709 can be fit into 6341 8 times, resulting in a remainder of 669.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5672 from 6341 leaves us with 669.
Include the next digit (5) from the dividend after 669, then repeat: 6695 / 709

Moving on to step 5:
When dividing 6695 by 709, we get 9 with a remainder of 314.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 6381 from 6695 leaves us with 314.
Bring next digit (7) of the dividend behind the 314 and repeat the process: 3147 / 709

Moving on to step 6:
If we divide 3147 by 709, we get 4 and a remainder of 311.
Write down 4 as next digit of the result. 
Result so far: 894.0
The remainder is 311 after subtracting 2836 from 3147.
Bring next digit (3) of the dividend behind the 311 and repeat the process: 3113 / 709

On to step 7:
The number 709 fits into 3113 4 times, leaving a remainder of 277.
Record the quotient 4 as the next digit in the result. 
Result so far: 8944.0
The remainder is 277 after subtracting 2836 from 3113.
Append the next digit (9) from the dividend to 277 and continue with: 2779 / 709

On to step 8:
The number 709 fits into 2779 3 times, leaving a remainder of 652.
Use 3 as the next digit of our solution. 
Result so far: 89443.0
If we subtract 2127 from 2779, we get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 9:
6520 divided by 709 is 9 with a remainder of 139.
Use 9 as the next digit of our solution. 
Result so far: 89443.9
Deduct 6381 from 6520 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 10:
1390 divided by 709 is 1 with a remainder of 681.
Put 1 as the next digit of the answer. 
Result so far: 89443.91
Subtract 709 from 1390 to get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Step 11:
709 can be fit into 6810 9 times, resulting in a remainder of 429.
The number 9 becomes the next digit in our result. 
Result so far: 89443.919
If we take 6381 away from 6810, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 12:
709 can be fit into 4290 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 89443.9196
Subtracting 4254 from 4290 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 709 fits into 360 0 times, leaving a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 89443.9196
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 14:
709 can be fit into 3600 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 89443.919605
If we take 3545 away from 3600, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 15:
The number 709 fits into 550 0 times, leaving a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 89443.919605
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 16:
The number 709 fits into 5500 7 times, leaving a remainder of 537.
The next digit of our result is 7. 
Result so far: 89443.91960507
Subtracting 4963 from 5500 leaves us with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

The final result is 89443.91960507 with a remainder of 5.37e-07.
