Let's divide 3946989 by 418
We're looking to find how many times 418 goes into 3946989.

Step 1:
3 divided by 418 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 418

Moving on to step 2:
39 divided by 418 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 418

Advancing to step 3:
When dividing 394 by 418, we get 0 with a remainder of 394.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 394 and we're left with 394.
Include the next digit (6) from the dividend after 394, then repeat: 3946 / 418

Step 4:
418 goes into 3946 9 times with a remainder of 184.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 3762 from 3946, we get 184.
Bring next digit (9) of the dividend behind the 184 and repeat the process: 1849 / 418

Let's proceed to step 5:
The number 418 fits into 1849 4 times, leaving a remainder of 177.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we subtract 1672 from 1849, we get 177.
Append the next digit (8) from the dividend to 177 and continue with: 1778 / 418

On to step 6:
When dividing 1778 by 418, we get 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 944.0
The remainder is 106 after subtracting 1672 from 1778.
Fetch the next digit (9) from the dividend, attach it to 106 and continue: 1069 / 418

On to step 7:
If we divide 1069 by 418, we get 2 and a remainder of 233.
Put 2 as the next digit of the answer. 
Result so far: 9442.0
Deduct 836 from 1069 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 8:
418 goes into 2330 5 times with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 9442.5
If we take 2090 away from 2330, 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.

Step 9:
418 goes into 2400 5 times with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 9442.55
Subtract 2090 from 2400 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 9442.55 with a balance of 0.31.
