We divide 71709636 by 784
The aim is to understand the frequency of 784 in 71709636.

Let's proceed to step 1:
7 divided by 784 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 784

Let's proceed to step 2:
784 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 784

Advancing to step 3:
When dividing 717 by 784, we get 0 with a remainder of 717.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 717, we get 717.
Append the next digit (0) from the dividend to 717 and continue with: 7170 / 784

On to step 4:
784 can be fit into 7170 9 times, resulting in a remainder of 114.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7056 away from 7170, we end up with 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 784

Moving on to step 5:
If we divide 1149 by 784, we get 1 and a remainder of 365.
The next digit of our result is 1. 
Result so far: 91.0
Subtract 784 from 1149 to get 365.
Fetch the next digit (6) from the dividend, attach it to 365 and continue: 3656 / 784

Going ahead to step 6:
If we divide 3656 by 784, we get 4 and a remainder of 520.
The next digit of our result is 4. 
Result so far: 914.0
If we take 3136 away from 3656, we end up with 520.
Grab the next digit (3) from the dividend, add it to 520, then carry on: 5203 / 784

Step 7:
If we divide 5203 by 784, we get 6 and a remainder of 499.
The number 6 becomes the next digit in our result. 
Result so far: 9146.0
The remainder is 499 after subtracting 4704 from 5203.
Fetch the next digit (6) from the dividend, attach it to 499 and continue: 4996 / 784

Let's proceed to step 8:
4996 divided by 784 is 6 with a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 91466.0
Subtract 4704 from 4996 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 9:
784 can be fit into 2920 3 times, resulting in a remainder of 568.
Use 3 as the next digit of our solution. 
Result so far: 91466.3
Subtracting 2352 from 2920 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 10:
The number 784 fits into 5680 7 times, leaving a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 91466.37
Subtracting 5488 from 5680 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
784 can be fit into 1920 2 times, resulting in a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 91466.372
If we subtract 1568 from 1920, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 12:
784 can be fit into 3520 4 times, resulting in a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 91466.3724
The remainder is 384 after subtracting 3136 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 13:
If we divide 3840 by 784, we get 4 and a remainder of 704.
Record the quotient 4 as the next digit in the result. 
Result so far: 91466.37244
Deduct 3136 from 3840 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final outcome is 91466.37244, with a leftover of 0.000704.
