Let's divide 3498415 by 486
Let's see how many times 486 fits into 3498415.

On to step 1:
3 divided by 486 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 486

Advancing to step 2:
The number 486 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 486

Going ahead to step 3:
349 divided by 486 is 0 with a remainder of 349.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 349 after subtracting 0 from 349.
Include the next digit (8) from the dividend after 349, then repeat: 3498 / 486

Step 4:
3498 divided by 486 is 7 with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 3402 away from 3498, we end up with 96.
Take the next digit (4) from the dividend and append it to 96, then repeat: 964 / 486

Step 5:
486 goes into 964 1 times with a remainder of 478.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 486 from 964 leaves us with 478.
Fetch the next digit (1) from the dividend, attach it to 478 and continue: 4781 / 486

Let's proceed to step 6:
If we divide 4781 by 486, we get 9 and a remainder of 407.
Use 9 as the next digit of our solution. 
Result so far: 719.0
Deduct 4374 from 4781 and we're left with 407.
Include the next digit (5) from the dividend after 407, then repeat: 4075 / 486

Let's proceed to step 7:
486 can be fit into 4075 8 times, resulting in a remainder of 187.
Write down 8 as next digit of the result. 
Result so far: 7198.0
Deduct 3888 from 4075 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 8:
If we divide 1870 by 486, we get 3 and a remainder of 412.
Use 3 as the next digit of our solution. 
Result so far: 7198.3
Subtract 1458 from 1870 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 9:
486 can be fit into 4120 8 times, resulting in a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 7198.38
Subtract 3888 from 4120 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
The number 486 fits into 2320 4 times, leaving a remainder of 376.
Use 4 as the next digit of our solution. 
Result so far: 7198.384
If we subtract 1944 from 2320, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
If we divide 3760 by 486, we get 7 and a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 7198.3847
Subtract 3402 from 3760 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 12:
If we divide 3580 by 486, we get 7 and a remainder of 178.
The number 7 becomes the next digit in our result. 
Result so far: 7198.38477
If we take 3402 away from 3580, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final result is 7198.38477 with a remainder of 0.000178.
