30234805 ÷ 806 
The aim is to understand the frequency of 806 in 30234805.

On to step 1:
3 divided by 806 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 806

Step 2:
806 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 806

Advancing to step 3:
When dividing 302 by 806, we get 0 with a remainder of 302.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 302, we get 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 806

Let's proceed to step 4:
806 goes into 3023 3 times with a remainder of 605.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2418 away from 3023, we end up with 605.
Bring next digit (4) of the dividend behind the 605 and repeat the process: 6054 / 806

Let's proceed to step 5:
When dividing 6054 by 806, we get 7 with a remainder of 412.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 5642 from 6054, we get 412.
Take the next digit (8) from the dividend and append it to 412, then repeat: 4128 / 806

Advancing to step 6:
The number 806 fits into 4128 5 times, leaving a remainder of 98.
Put 5 as the next digit of the answer. 
Result so far: 375.0
If we take 4030 away from 4128, we end up with 98.
Take the next digit (0) from the dividend and append it to 98, then repeat: 980 / 806

Moving on to step 7:
806 can be fit into 980 1 times, resulting in a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 3751.0
If we subtract 806 from 980, we get 174.
Append the next digit (5) from the dividend to 174 and continue with: 1745 / 806

On to step 8:
806 can be fit into 1745 2 times, resulting in a remainder of 133.
Use 2 as the next digit of our solution. 
Result so far: 37512.0
Subtract 1612 from 1745 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 9:
When dividing 1330 by 806, we get 1 with a remainder of 524.
Put 1 as the next digit of the answer. 
Result so far: 37512.1
Deduct 806 from 1330 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 10:
5240 divided by 806 is 6 with a remainder of 404.
Put 6 as the next digit of the answer. 
Result so far: 37512.16
If we take 4836 away from 5240, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
If we divide 4040 by 806, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 37512.165
Subtracting 4030 from 4040 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
806 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 37512.165
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
When dividing 1000 by 806, we get 1 with a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 37512.16501
Subtract 806 from 1000 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 14:
1940 divided by 806 is 2 with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 37512.165012
Deduct 1612 from 1940 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 15:
806 can be fit into 3280 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 37512.1650124
If we take 3224 away from 3280, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 16:
806 goes into 560 0 times with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 37512.1650124
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 37512.1650124 with a remainder of 5.6e-07.
