840486 ÷ 46 
We want to figure out the number of times 840486 can be divided by 46.

Going ahead to step 1:
46 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 46

Step 2:
The number 46 fits into 84 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 46 from 84 to get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 46

Going ahead to step 3:
The number 46 fits into 380 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 12 after subtracting 368 from 380.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 46

Step 4:
The number 46 fits into 124 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 182.0
The remainder is 32 after subtracting 92 from 124.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 46

Step 5:
328 divided by 46 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 1827.0
Subtract 322 from 328 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 46

Advancing to step 6:
When dividing 66 by 46, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 18271.0
If we subtract 46 from 66, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 46 fits into 200 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 18271.4
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 46 fits into 160 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 18271.43
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
46 goes into 220 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 18271.434
Deduct 184 from 220 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
If we divide 360 by 46, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 18271.4347
Subtract 322 from 360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
If we divide 380 by 46, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 18271.43478
Subtract 368 from 380 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
120 divided by 46 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 18271.434782
If we subtract 92 from 120, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
46 goes into 280 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 18271.4347826
If we subtract 276 from 280, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
When dividing 40 by 46, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 18271.4347826
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 18271.4347826, and the remainder is 4e-08.
