Let's divide 18521213 by 716
The aim is to understand the frequency of 716 in 18521213.

Moving on to step 1:
716 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 716

On to step 2:
716 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 716

Advancing to step 3:
716 can be fit into 185 0 times, resulting in a remainder of 185.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 185 leaves us with 185.
Include the next digit (2) from the dividend after 185, then repeat: 1852 / 716

Going ahead to step 4:
The number 716 fits into 1852 2 times, leaving a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1432 from 1852 and we're left with 420.
Include the next digit (1) from the dividend after 420, then repeat: 4201 / 716

Advancing to step 5:
4201 divided by 716 is 5 with a remainder of 621.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 3580 away from 4201, we end up with 621.
Grab the next digit (2) from the dividend, add it to 621, then carry on: 6212 / 716

Moving on to step 6:
When dividing 6212 by 716, we get 8 with a remainder of 484.
The next digit of our result is 8. 
Result so far: 258.0
The remainder is 484 after subtracting 5728 from 6212.
Grab the next digit (1) from the dividend, add it to 484, then carry on: 4841 / 716

Moving on to step 7:
The number 716 fits into 4841 6 times, leaving a remainder of 545.
Use 6 as the next digit of our solution. 
Result so far: 2586.0
Deduct 4296 from 4841 and we're left with 545.
Grab the next digit (3) from the dividend, add it to 545, then carry on: 5453 / 716

Advancing to step 8:
If we divide 5453 by 716, we get 7 and a remainder of 441.
Put 7 as the next digit of the answer. 
Result so far: 25867.0
If we subtract 5012 from 5453, we get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 9:
When dividing 4410 by 716, we get 6 with a remainder of 114.
The number 6 becomes the next digit in our result. 
Result so far: 25867.6
If we take 4296 away from 4410, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
1140 divided by 716 is 1 with a remainder of 424.
Put 1 as the next digit of the answer. 
Result so far: 25867.61
If we subtract 716 from 1140, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
If we divide 4240 by 716, we get 5 and a remainder of 660.
Put 5 as the next digit of the answer. 
Result so far: 25867.615
Subtracting 3580 from 4240 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 12:
716 goes into 6600 9 times with a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 25867.6159
If we subtract 6444 from 6600, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 13:
When dividing 1560 by 716, we get 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 25867.61592
The remainder is 128 after subtracting 1432 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
If we divide 1280 by 716, we get 1 and a remainder of 564.
Write down 1 as next digit of the result. 
Result so far: 25867.615921
Subtracting 716 from 1280 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 15:
5640 divided by 716 is 7 with a remainder of 628.
Use 7 as the next digit of our solution. 
Result so far: 25867.6159217
Subtract 5012 from 5640 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 16:
The number 716 fits into 6280 8 times, leaving a remainder of 552.
Put 8 as the next digit of the answer. 
Result so far: 25867.61592178
Deduct 5728 from 6280 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final outcome is 25867.61592178, with a leftover of 5.52e-07.
