Let's divide 2520396 by 840
We're looking to find how many times 840 goes into 2520396.

Let's proceed to step 1:
2 divided by 840 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 840

Let's proceed to step 2:
If we divide 25 by 840, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 840

Moving on to step 3:
252 divided by 840 is 0 with a remainder of 252.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 252 and we're left with 252.
Append the next digit (0) from the dividend to 252 and continue with: 2520 / 840

Moving on to step 4:
2520 divided by 840 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2520 away from 2520, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 840

On to step 5:
If we divide 3 by 840, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 840

Moving on to step 6:
When dividing 39 by 840, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 300.0
If we subtract 0 from 39, we get 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 840

Let's proceed to step 7:
840 goes into 396 0 times with a remainder of 396.
Write down 0 as next digit of the result. 
Result so far: 3000.0
If we take 0 away from 396, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 8:
When dividing 3960 by 840, we get 4 with a remainder of 600.
The number 4 becomes the next digit in our result. 
Result so far: 3000.4
If we take 3360 away from 3960, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 9:
If we divide 6000 by 840, we get 7 and a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 3000.47
If we take 5880 away from 6000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
1200 divided by 840 is 1 with a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 3000.471
If we take 840 away from 1200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
3600 divided by 840 is 4 with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 3000.4714
If we take 3360 away from 3600, we end up with 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 12:
840 goes into 2400 2 times with a remainder of 720.
Use 2 as the next digit of our solution. 
Result so far: 3000.47142
Subtracting 1680 from 2400 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 13:
When dividing 7200 by 840, we get 8 with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 3000.471428
Deduct 6720 from 7200 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 14:
840 can be fit into 4800 5 times, resulting in a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 3000.4714285
If we subtract 4200 from 4800, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 15:
When dividing 6000 by 840, we get 7 with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 3000.47142857
If we subtract 5880 from 6000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 3000.47142857, and the remainder is 1.2e-07.
