Let's divide 17212342 by 806
The aim is to understand the frequency of 806 in 17212342.

Step 1:
When dividing 1 by 806, we get 0 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.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 806

Going ahead to step 2:
17 divided by 806 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 806

On to step 3:
When dividing 172 by 806, we get 0 with a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 172 and we're left with 172.
Include the next digit (1) from the dividend after 172, then repeat: 1721 / 806

Step 4:
806 can be fit into 1721 2 times, resulting in a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1612 from 1721 to get 109.
Fetch the next digit (2) from the dividend, attach it to 109 and continue: 1092 / 806

On to step 5:
806 can be fit into 1092 1 times, resulting in a remainder of 286.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 806 from 1092 and we're left with 286.
Grab the next digit (3) from the dividend, add it to 286, then carry on: 2863 / 806

Moving on to step 6:
If we divide 2863 by 806, we get 3 and a remainder of 445.
Use 3 as the next digit of our solution. 
Result so far: 213.0
If we take 2418 away from 2863, we end up with 445.
Fetch the next digit (4) from the dividend, attach it to 445 and continue: 4454 / 806

Step 7:
The number 806 fits into 4454 5 times, leaving a remainder of 424.
Write down 5 as next digit of the result. 
Result so far: 2135.0
The remainder is 424 after subtracting 4030 from 4454.
Take the next digit (2) from the dividend and append it to 424, then repeat: 4242 / 806

On to step 8:
If we divide 4242 by 806, we get 5 and a remainder of 212.
Record the quotient 5 as the next digit in the result. 
Result so far: 21355.0
Subtract 4030 from 4242 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 9:
806 goes into 2120 2 times with a remainder of 508.
Use 2 as the next digit of our solution. 
Result so far: 21355.2
Deduct 1612 from 2120 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 10:
The number 806 fits into 5080 6 times, leaving a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 21355.26
If we subtract 4836 from 5080, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 11:
2440 divided by 806 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 21355.263
Deduct 2418 from 2440 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
When dividing 220 by 806, we get 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 21355.263
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
When dividing 2200 by 806, we get 2 with a remainder of 588.
The next digit of our result is 2. 
Result so far: 21355.26302
Deduct 1612 from 2200 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 14:
When dividing 5880 by 806, we get 7 with a remainder of 238.
The next digit of our result is 7. 
Result so far: 21355.263027
The remainder is 238 after subtracting 5642 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 15:
The number 806 fits into 2380 2 times, leaving a remainder of 768.
Write down 2 as next digit of the result. 
Result so far: 21355.2630272
If we subtract 1612 from 2380, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 16:
7680 divided by 806 is 9 with a remainder of 426.
Write down 9 as next digit of the result. 
Result so far: 21355.26302729
Subtracting 7254 from 7680 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

After the division, we end up with 21355.26302729 and a remainder of 4.26e-07.
