We're dividing 891724 by 3 
Our goal is to divide 891724 by 3.

Step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Going ahead to step 2:
When dividing 29 by 3, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 27 from 29 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

On to step 3:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
Subtract 21 from 21 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Moving on to step 4:
7 divided by 3 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2972.0
Subtracting 6 from 7 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Going ahead to step 5:
If we divide 12 by 3, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 29724.0
Subtract 12 from 12 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Step 6:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 297241.0
Deduct 3 from 4 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 297241.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 297241.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 297241.33 and a remainder of 0.001.
