99507551 ÷ 709 
The aim is to understand the frequency of 709 in 99507551.

On to step 1:
If we divide 9 by 709, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 709

Step 2:
If we divide 99 by 709, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 709

On to step 3:
When dividing 995 by 709, we get 1 with a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 709 from 995 leaves us with 286.
Include the next digit (0) from the dividend after 286, then repeat: 2860 / 709

Advancing to step 4:
709 can be fit into 2860 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 2836 from 2860 to get 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 709

Step 5:
247 divided by 709 is 0 with a remainder of 247.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 247, we get 247.
Append the next digit (5) from the dividend to 247 and continue with: 2475 / 709

Going ahead to step 6:
709 can be fit into 2475 3 times, resulting in a remainder of 348.
Use 3 as the next digit of our solution. 
Result so far: 1403.0
The remainder is 348 after subtracting 2127 from 2475.
Include the next digit (5) from the dividend after 348, then repeat: 3485 / 709

Let's proceed to step 7:
3485 divided by 709 is 4 with a remainder of 649.
The number 4 becomes the next digit in our result. 
Result so far: 14034.0
If we subtract 2836 from 3485, we get 649.
Include the next digit (1) from the dividend after 649, then repeat: 6491 / 709

On to step 8:
When dividing 6491 by 709, we get 9 with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 140349.0
Subtracting 6381 from 6491 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.

On to step 9:
709 can be fit into 1100 1 times, resulting in a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 140349.1
If we take 709 away from 1100, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 10:
3910 divided by 709 is 5 with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 140349.15
Subtracting 3545 from 3910 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 11:
When dividing 3650 by 709, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 140349.155
If we subtract 3545 from 3650, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

After the division, we end up with 140349.155 and a remainder of 0.0105.
