Let's divide 2743458 by 858
We're looking to find how many times 858 goes into 2743458.

On to step 1:
The number 858 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 858

Moving on to step 2:
858 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 858

Moving on to step 3:
858 can be fit into 274 0 times, resulting in a remainder of 274.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 274 to get 274.
Bring next digit (3) of the dividend behind the 274 and repeat the process: 2743 / 858

Let's proceed to step 4:
The number 858 fits into 2743 3 times, leaving a remainder of 169.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2574 from 2743 to get 169.
Fetch the next digit (4) from the dividend, attach it to 169 and continue: 1694 / 858

Step 5:
When dividing 1694 by 858, we get 1 with a remainder of 836.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 858 away from 1694, we end up with 836.
Bring next digit (5) of the dividend behind the 836 and repeat the process: 8365 / 858

Going ahead to step 6:
When dividing 8365 by 858, we get 9 with a remainder of 643.
Use 9 as the next digit of our solution. 
Result so far: 319.0
If we take 7722 away from 8365, we end up with 643.
Fetch the next digit (8) from the dividend, attach it to 643 and continue: 6438 / 858

On to step 7:
6438 divided by 858 is 7 with a remainder of 432.
The next digit of our result is 7. 
Result so far: 3197.0
Subtracting 6006 from 6438 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 8:
If we divide 4320 by 858, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3197.5
If we take 4290 away from 4320, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 858, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 3197.5
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
858 goes into 3000 3 times with a remainder of 426.
Record the quotient 3 as the next digit in the result. 
Result so far: 3197.503
Subtracting 2574 from 3000 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.

Advancing to step 11:
858 can be fit into 4260 4 times, resulting in a remainder of 828.
Write down 4 as next digit of the result. 
Result so far: 3197.5034
If we take 3432 away from 4260, we end up with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Let's proceed to step 12:
The number 858 fits into 8280 9 times, leaving a remainder of 558.
Record the quotient 9 as the next digit in the result. 
Result so far: 3197.50349
Subtract 7722 from 8280 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 13:
5580 divided by 858 is 6 with a remainder of 432.
The number 6 becomes the next digit in our result. 
Result so far: 3197.503496
Deduct 5148 from 5580 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 14:
The number 858 fits into 4320 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 3197.5034965
If we take 4290 away from 4320, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
When dividing 300 by 858, we get 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 3197.5034965
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 3197.5034965 with a remaining 3e-07.
