We look at the division of 63686358 by 726 
The aim is to understand the frequency of 726 in 63686358.

On to step 1:
When dividing 6 by 726, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 726

Step 2:
726 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 726

On to step 3:
When dividing 636 by 726, we get 0 with a remainder of 636.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 636 and we're left with 636.
Append the next digit (8) from the dividend to 636 and continue with: 6368 / 726

Step 4:
The number 726 fits into 6368 8 times, leaving a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 5808 from 6368, we get 560.
Grab the next digit (6) from the dividend, add it to 560, then carry on: 5606 / 726

Moving on to step 5:
If we divide 5606 by 726, we get 7 and a remainder of 524.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 5082 from 5606 to get 524.
Include the next digit (3) from the dividend after 524, then repeat: 5243 / 726

Advancing to step 6:
726 can be fit into 5243 7 times, resulting in a remainder of 161.
Use 7 as the next digit of our solution. 
Result so far: 877.0
If we take 5082 away from 5243, we end up with 161.
Append the next digit (5) from the dividend to 161 and continue with: 1615 / 726

Advancing to step 7:
1615 divided by 726 is 2 with a remainder of 163.
The number 2 becomes the next digit in our result. 
Result so far: 8772.0
Subtracting 1452 from 1615 leaves us with 163.
Grab the next digit (8) from the dividend, add it to 163, then carry on: 1638 / 726

Moving on to step 8:
726 can be fit into 1638 2 times, resulting in a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 87722.0
Deduct 1452 from 1638 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 9:
726 can be fit into 1860 2 times, resulting in a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 87722.2
The remainder is 408 after subtracting 1452 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
726 goes into 4080 5 times with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 87722.25
If we take 3630 away from 4080, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 11:
If we divide 4500 by 726, we get 6 and a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 87722.256
Deduct 4356 from 4500 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
726 can be fit into 1440 1 times, resulting in a remainder of 714.
Write down 1 as next digit of the result. 
Result so far: 87722.2561
The remainder is 714 after subtracting 726 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Let's proceed to step 13:
726 goes into 7140 9 times with a remainder of 606.
Put 9 as the next digit of the answer. 
Result so far: 87722.25619
The remainder is 606 after subtracting 6534 from 7140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Step 14:
726 can be fit into 6060 8 times, resulting in a remainder of 252.
The next digit of our result is 8. 
Result so far: 87722.256198
The remainder is 252 after subtracting 5808 from 6060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 15:
726 goes into 2520 3 times with a remainder of 342.
Use 3 as the next digit of our solution. 
Result so far: 87722.2561983
If we subtract 2178 from 2520, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 16:
When dividing 3420 by 726, we get 4 with a remainder of 516.
Write down 4 as next digit of the result. 
Result so far: 87722.25619834
Subtracting 2904 from 3420 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Our division results in 87722.25619834 with a remaining 5.16e-07.
