11580842 ÷ 840 
We want to divide 11580842 by 840.

Let's proceed to step 1:
If we divide 1 by 840, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 840

Moving on to step 2:
The number 840 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 840

Advancing to step 3:
840 goes into 115 0 times with a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 115 leaves us with 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 840

Moving on to step 4:
When dividing 1158 by 840, we get 1 with a remainder of 318.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 840 from 1158 and we're left with 318.
Include the next digit (0) from the dividend after 318, then repeat: 3180 / 840

On to step 5:
When dividing 3180 by 840, we get 3 with a remainder of 660.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 2520 from 3180 leaves us with 660.
Take the next digit (8) from the dividend and append it to 660, then repeat: 6608 / 840

On to step 6:
840 can be fit into 6608 7 times, resulting in a remainder of 728.
Put 7 as the next digit of the answer. 
Result so far: 137.0
The remainder is 728 after subtracting 5880 from 6608.
Grab the next digit (4) from the dividend, add it to 728, then carry on: 7284 / 840

Advancing to step 7:
840 goes into 7284 8 times with a remainder of 564.
Use 8 as the next digit of our solution. 
Result so far: 1378.0
Subtracting 6720 from 7284 leaves us with 564.
Include the next digit (2) from the dividend after 564, then repeat: 5642 / 840

Step 8:
The number 840 fits into 5642 6 times, leaving a remainder of 602.
Use 6 as the next digit of our solution. 
Result so far: 13786.0
If we take 5040 away from 5642, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 9:
840 can be fit into 6020 7 times, resulting in a remainder of 140.
Write down 7 as next digit of the result. 
Result so far: 13786.7
If we take 5880 away from 6020, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
When dividing 1400 by 840, we get 1 with a remainder of 560.
Write down 1 as next digit of the result. 
Result so far: 13786.71
Deduct 840 from 1400 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
5600 divided by 840 is 6 with a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 13786.716
If we subtract 5040 from 5600, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 12:
When dividing 5600 by 840, we get 6 with a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 13786.7166
If we take 5040 away from 5600, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

In conclusion, the division gives 13786.7166 with a balance of 0.0056.
