We're dividing 17364759 by 840 
Let's see how many times 840 fits into 17364759.

Advancing to step 1:
If we divide 1 by 840, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 840

Going ahead to step 2:
840 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.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 840

Step 3:
When dividing 173 by 840, we get 0 with a remainder of 173.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 173, we end up with 173.
Append the next digit (6) from the dividend to 173 and continue with: 1736 / 840

Advancing to step 4:
840 can be fit into 1736 2 times, resulting in a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1680 from 1736, we get 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 840

Moving on to step 5:
When dividing 564 by 840, we get 0 with a remainder of 564.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 564 after subtracting 0 from 564.
Include the next digit (7) from the dividend after 564, then repeat: 5647 / 840

On to step 6:
840 can be fit into 5647 6 times, resulting in a remainder of 607.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we take 5040 away from 5647, we end up with 607.
Include the next digit (5) from the dividend after 607, then repeat: 6075 / 840

On to step 7:
840 can be fit into 6075 7 times, resulting in a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 2067.0
If we take 5880 away from 6075, we end up with 195.
Take the next digit (9) from the dividend and append it to 195, then repeat: 1959 / 840

On to step 8:
The number 840 fits into 1959 2 times, leaving a remainder of 279.
The number 2 becomes the next digit in our result. 
Result so far: 20672.0
If we take 1680 away from 1959, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 9:
840 goes into 2790 3 times with a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 20672.3
If we subtract 2520 from 2790, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
If we divide 2700 by 840, we get 3 and a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 20672.33
Subtracting 2520 from 2700 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 20672.33 and a remainder of 0.18.
