We're dividing 15399204 by 486 
We want to divide 15399204 by 486.

Advancing to step 1:
If we divide 1 by 486, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 486

Step 2:
When dividing 15 by 486, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 486

Moving on to step 3:
When dividing 153 by 486, we get 0 with a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Include the next digit (9) from the dividend after 153, then repeat: 1539 / 486

Step 4:
486 goes into 1539 3 times with a remainder of 81.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 81 after subtracting 1458 from 1539.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 486

Going ahead to step 5:
486 can be fit into 819 1 times, resulting in a remainder of 333.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 333 after subtracting 486 from 819.
Grab the next digit (2) from the dividend, add it to 333, then carry on: 3332 / 486

Advancing to step 6:
3332 divided by 486 is 6 with a remainder of 416.
The next digit of our result is 6. 
Result so far: 316.0
If we take 2916 away from 3332, we end up with 416.
Include the next digit (0) from the dividend after 416, then repeat: 4160 / 486

Let's proceed to step 7:
If we divide 4160 by 486, we get 8 and a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 3168.0
Subtracting 3888 from 4160 leaves us with 272.
Take the next digit (4) from the dividend and append it to 272, then repeat: 2724 / 486

Let's proceed to step 8:
When dividing 2724 by 486, we get 5 with a remainder of 294.
Use 5 as the next digit of our solution. 
Result so far: 31685.0
Subtract 2430 from 2724 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 9:
2940 divided by 486 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 31685.6
Deduct 2916 from 2940 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 486 fits into 240 0 times, leaving a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 31685.6
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
486 goes into 2400 4 times with a remainder of 456.
The next digit of our result is 4. 
Result so far: 31685.604
The remainder is 456 after subtracting 1944 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 12:
If we divide 4560 by 486, we get 9 and a remainder of 186.
The number 9 becomes the next digit in our result. 
Result so far: 31685.6049
The remainder is 186 after subtracting 4374 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 13:
1860 divided by 486 is 3 with a remainder of 402.
Write down 3 as next digit of the result. 
Result so far: 31685.60493
Subtract 1458 from 1860 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 14:
If we divide 4020 by 486, we get 8 and a remainder of 132.
The next digit of our result is 8. 
Result so far: 31685.604938
The remainder is 132 after subtracting 3888 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 15:
486 can be fit into 1320 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 31685.6049382
Deduct 972 from 1320 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 16:
486 can be fit into 3480 7 times, resulting in a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 31685.60493827
Subtract 3402 from 3480 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 31685.60493827 with a remaining 7.8e-08.
