15216904 ÷ 706 
The aim is to understand the frequency of 706 in 15216904.

Advancing to step 1:
706 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 706

On to step 2:
When dividing 15 by 706, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 706

On to step 3:
If we divide 152 by 706, we get 0 and a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Bring next digit (1) of the dividend behind the 152 and repeat the process: 1521 / 706

On to step 4:
The number 706 fits into 1521 2 times, leaving a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1412 from 1521 leaves us with 109.
Bring next digit (6) of the dividend behind the 109 and repeat the process: 1096 / 706

Going ahead to step 5:
706 can be fit into 1096 1 times, resulting in a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 390 after subtracting 706 from 1096.
Include the next digit (9) from the dividend after 390, then repeat: 3909 / 706

Moving on to step 6:
3909 divided by 706 is 5 with a remainder of 379.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
If we subtract 3530 from 3909, we get 379.
Take the next digit (0) from the dividend and append it to 379, then repeat: 3790 / 706

Let's proceed to step 7:
When dividing 3790 by 706, we get 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 2155.0
The remainder is 260 after subtracting 3530 from 3790.
Fetch the next digit (4) from the dividend, attach it to 260 and continue: 2604 / 706

Going ahead to step 8:
706 goes into 2604 3 times with a remainder of 486.
Record the quotient 3 as the next digit in the result. 
Result so far: 21553.0
If we subtract 2118 from 2604, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 9:
706 can be fit into 4860 6 times, resulting in a remainder of 624.
Record the quotient 6 as the next digit in the result. 
Result so far: 21553.6
If we subtract 4236 from 4860, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 10:
706 goes into 6240 8 times with a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 21553.68
If we take 5648 away from 6240, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 11:
If we divide 5920 by 706, we get 8 and a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 21553.688
Subtract 5648 from 5920 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 21553.688, and the remainder is 0.0272.
