We divide 21514920 by 726
The aim is to understand the frequency of 726 in 21514920.

Step 1:
726 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 726

Advancing to step 2:
726 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 726

Advancing to step 3:
215 divided by 726 is 0 with a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Grab the next digit (1) from the dividend, add it to 215, then carry on: 2151 / 726

Let's proceed to step 4:
When dividing 2151 by 726, we get 2 with a remainder of 699.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1452 away from 2151, we end up with 699.
Fetch the next digit (4) from the dividend, attach it to 699 and continue: 6994 / 726

Step 5:
726 goes into 6994 9 times with a remainder of 460.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 6534 from 6994 to get 460.
Fetch the next digit (9) from the dividend, attach it to 460 and continue: 4609 / 726

Let's proceed to step 6:
The number 726 fits into 4609 6 times, leaving a remainder of 253.
Write down 6 as next digit of the result. 
Result so far: 296.0
If we subtract 4356 from 4609, we get 253.
Bring next digit (2) of the dividend behind the 253 and repeat the process: 2532 / 726

Advancing to step 7:
The number 726 fits into 2532 3 times, leaving a remainder of 354.
Record the quotient 3 as the next digit in the result. 
Result so far: 2963.0
Subtracting 2178 from 2532 leaves us with 354.
Fetch the next digit (0) from the dividend, attach it to 354 and continue: 3540 / 726

Let's proceed to step 8:
726 can be fit into 3540 4 times, resulting in a remainder of 636.
Record the quotient 4 as the next digit in the result. 
Result so far: 29634.0
Subtract 2904 from 3540 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.

Advancing to step 9:
When dividing 6360 by 726, we get 8 with a remainder of 552.
The next digit of our result is 8. 
Result so far: 29634.8
The remainder is 552 after subtracting 5808 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 10:
When dividing 5520 by 726, we get 7 with a remainder of 438.
Record the quotient 7 as the next digit in the result. 
Result so far: 29634.87
Subtracting 5082 from 5520 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 11:
If we divide 4380 by 726, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 29634.876
Deduct 4356 from 4380 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 726, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 29634.876
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
726 can be fit into 2400 3 times, resulting in a remainder of 222.
Record the quotient 3 as the next digit in the result. 
Result so far: 29634.87603
The remainder is 222 after subtracting 2178 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 14:
726 can be fit into 2220 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 29634.876033
If we take 2178 away from 2220, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 29634.876033 with a balance of 4.2e-06.
