2170663 divided by 830 
The aim is to understand the frequency of 830 in 2170663.

Step 1:
830 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
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 / 830

Advancing to step 2:
21 divided by 830 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 830

Step 3:
If we divide 217 by 830, we get 0 and a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 217 after subtracting 0 from 217.
Include the next digit (0) from the dividend after 217, then repeat: 2170 / 830

Step 4:
830 goes into 2170 2 times with a remainder of 510.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1660 from 2170 and we're left with 510.
Fetch the next digit (6) from the dividend, attach it to 510 and continue: 5106 / 830

Going ahead to step 5:
830 can be fit into 5106 6 times, resulting in a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 4980 from 5106 leaves us with 126.
Grab the next digit (6) from the dividend, add it to 126, then carry on: 1266 / 830

Let's proceed to step 6:
The number 830 fits into 1266 1 times, leaving a remainder of 436.
Use 1 as the next digit of our solution. 
Result so far: 261.0
If we take 830 away from 1266, we end up with 436.
Take the next digit (3) from the dividend and append it to 436, then repeat: 4363 / 830

Let's proceed to step 7:
When dividing 4363 by 830, we get 5 with a remainder of 213.
Record the quotient 5 as the next digit in the result. 
Result so far: 2615.0
Subtract 4150 from 4363 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 8:
830 goes into 2130 2 times with a remainder of 470.
Put 2 as the next digit of the answer. 
Result so far: 2615.2
Deduct 1660 from 2130 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 9:
4700 divided by 830 is 5 with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 2615.25
Deduct 4150 from 4700 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 10:
830 can be fit into 5500 6 times, resulting in a remainder of 520.
Put 6 as the next digit of the answer. 
Result so far: 2615.256
Deduct 4980 from 5500 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 11:
The number 830 fits into 5200 6 times, leaving a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 2615.2566
If we take 4980 away from 5200, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 2615.2566 with a remainder of 0.0022.
