17812803 ÷ 806 
We want to figure out the number of times 17812803 can be divided by 806.

Let's proceed to step 1:
When dividing 1 by 806, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 806

Advancing to step 2:
806 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 806

Moving on to step 3:
806 goes into 178 0 times with a remainder of 178.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 178, we get 178.
Bring next digit (1) of the dividend behind the 178 and repeat the process: 1781 / 806

Going ahead to step 4:
806 goes into 1781 2 times with a remainder of 169.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1612 from 1781 to get 169.
Include the next digit (2) from the dividend after 169, then repeat: 1692 / 806

On to step 5:
The number 806 fits into 1692 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 1612 from 1692 leaves us with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 806

Advancing to step 6:
808 divided by 806 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
If we subtract 806 from 808, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 806

Step 7:
806 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2210.0
If we take 0 away from 20, we end up with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 806

Let's proceed to step 8:
203 divided by 806 is 0 with a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 22100.0
If we subtract 0 from 203, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 9:
806 goes into 2030 2 times with a remainder of 418.
Put 2 as the next digit of the answer. 
Result so far: 22100.2
Deduct 1612 from 2030 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
If we divide 4180 by 806, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 22100.25
The remainder is 150 after subtracting 4030 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
The number 806 fits into 1500 1 times, leaving a remainder of 694.
The number 1 becomes the next digit in our result. 
Result so far: 22100.251
If we subtract 806 from 1500, we get 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 12:
806 goes into 6940 8 times with a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 22100.2518
Subtracting 6448 from 6940 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 13:
806 can be fit into 4920 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 22100.25186
Subtract 4836 from 4920 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
When dividing 840 by 806, we get 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 22100.251861
Subtracting 806 from 840 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 15:
340 divided by 806 is 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 22100.251861
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 16:
The number 806 fits into 3400 4 times, leaving a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 22100.25186104
If we take 3224 away from 3400, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Our division results in 22100.25186104 with a remaining 1.76e-07.
