We look at the division of 6781512 by 709 
The aim is to understand the frequency of 709 in 6781512.

Going ahead to step 1:
If we divide 6 by 709, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 709

Going ahead to step 2:
709 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 709

On to step 3:
709 can be fit into 678 0 times, resulting in a remainder of 678.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 678 after subtracting 0 from 678.
Fetch the next digit (1) from the dividend, attach it to 678 and continue: 6781 / 709

Let's proceed to step 4:
709 can be fit into 6781 9 times, resulting in a remainder of 400.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 6381 from 6781 and we're left with 400.
Grab the next digit (5) from the dividend, add it to 400, then carry on: 4005 / 709

Step 5:
4005 divided by 709 is 5 with a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
The remainder is 460 after subtracting 3545 from 4005.
Fetch the next digit (1) from the dividend, attach it to 460 and continue: 4601 / 709

On to step 6:
When dividing 4601 by 709, we get 6 with a remainder of 347.
Put 6 as the next digit of the answer. 
Result so far: 956.0
Subtract 4254 from 4601 to get 347.
Fetch the next digit (2) from the dividend, attach it to 347 and continue: 3472 / 709

Going ahead to step 7:
The number 709 fits into 3472 4 times, leaving a remainder of 636.
Use 4 as the next digit of our solution. 
Result so far: 9564.0
Subtract 2836 from 3472 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 8:
The number 709 fits into 6360 8 times, leaving a remainder of 688.
Put 8 as the next digit of the answer. 
Result so far: 9564.8
If we subtract 5672 from 6360, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 9:
709 can be fit into 6880 9 times, resulting in a remainder of 499.
Use 9 as the next digit of our solution. 
Result so far: 9564.89
If we take 6381 away from 6880, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

On to step 10:
When dividing 4990 by 709, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 9564.897
The remainder is 27 after subtracting 4963 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
709 can be fit into 270 0 times, resulting in a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 9564.897
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 12:
If we divide 2700 by 709, we get 3 and a remainder of 573.
The next digit of our result is 3. 
Result so far: 9564.89703
If we subtract 2127 from 2700, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 13:
The number 709 fits into 5730 8 times, leaving a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 9564.897038
Deduct 5672 from 5730 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
When dividing 580 by 709, we get 0 with a remainder of 580.
The next digit of our result is 0. 
Result so far: 9564.897038
The remainder is 580 after subtracting 0 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 15:
709 can be fit into 5800 8 times, resulting in a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 9564.89703808
If we take 5672 away from 5800, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 9564.89703808, and the remainder is 1.28e-07.
