986841 ÷ 42 
We want to divide 986841 by 42.

On to step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 42

On to step 2:
42 goes into 98 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 84 from 98 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 42

Moving on to step 3:
The number 42 fits into 146 3 times, leaving a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 126 from 146 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 42

On to step 4:
42 goes into 208 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 234.0
The remainder is 40 after subtracting 168 from 208.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 42

Let's proceed to step 5:
The number 42 fits into 404 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 2349.0
The remainder is 26 after subtracting 378 from 404.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 42

Advancing to step 6:
261 divided by 42 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 23496.0
Deduct 252 from 261 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 42, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 23496.2
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 23496.21
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 23496.214
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 23496.2142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
When dividing 360 by 42, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 23496.21428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
If we divide 240 by 42, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 23496.214285
Subtracting 210 from 240 leaves us 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.

Step 13:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 23496.2142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 23496.21428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 23496.21428571, with a leftover of 1.8e-08.
