17074224 divided by 858 
Our goal is to divide 17074224 by 858.

Moving on to step 1:
If we divide 1 by 858, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 858

On to step 2:
858 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 858

Going ahead to step 3:
858 can be fit into 170 0 times, resulting in a remainder of 170.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 170 and we're left with 170.
Take the next digit (7) from the dividend and append it to 170, then repeat: 1707 / 858

Let's proceed to step 4:
858 goes into 1707 1 times with a remainder of 849.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 858 from 1707 and we're left with 849.
Bring next digit (4) of the dividend behind the 849 and repeat the process: 8494 / 858

Let's proceed to step 5:
The number 858 fits into 8494 9 times, leaving a remainder of 772.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 7722 from 8494 leaves us with 772.
Fetch the next digit (2) from the dividend, attach it to 772 and continue: 7722 / 858

Advancing to step 6:
7722 divided by 858 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 199.0
The remainder is 0 after subtracting 7722 from 7722.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 858

On to step 7:
858 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: 1990.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 858

Moving on to step 8:
858 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 19900.0
Subtract 0 from 24 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
858 goes into 240 0 times with a remainder of 240.
The next digit of our result is 0. 
Result so far: 19900.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
858 can be fit into 2400 2 times, resulting in a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 19900.02
Subtracting 1716 from 2400 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 11:
6840 divided by 858 is 7 with a remainder of 834.
Record the quotient 7 as the next digit in the result. 
Result so far: 19900.027
Subtract 6006 from 6840 to get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Advancing to step 12:
858 goes into 8340 9 times with a remainder of 618.
Put 9 as the next digit of the answer. 
Result so far: 19900.0279
Deduct 7722 from 8340 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 13:
6180 divided by 858 is 7 with a remainder of 174.
The next digit of our result is 7. 
Result so far: 19900.02797
Subtracting 6006 from 6180 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 14:
1740 divided by 858 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 19900.027972
The remainder is 24 after subtracting 1716 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
If we divide 240 by 858, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 19900.027972
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
When dividing 2400 by 858, we get 2 with a remainder of 684.
Record the quotient 2 as the next digit in the result. 
Result so far: 19900.02797202
If we subtract 1716 from 2400, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

The final result is 19900.02797202 with a remainder of 6.84e-07.
