Let's divide 6399097 by 486
Our goal is to divide 6399097 by 486.

Moving on to step 1:
6 divided by 486 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 486

Moving on to step 2:
When dividing 63 by 486, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 486

Step 3:
If we divide 639 by 486, we get 1 and a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 486 from 639 to get 153.
Grab the next digit (9) from the dividend, add it to 153, then carry on: 1539 / 486

Moving on to step 4:
If we divide 1539 by 486, we get 3 and a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1458 from 1539 leaves us with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 486

Going ahead to step 5:
486 can be fit into 810 1 times, resulting in a remainder of 324.
The next digit of our result is 1. 
Result so far: 131.0
If we take 486 away from 810, we end up with 324.
Bring next digit (9) of the dividend behind the 324 and repeat the process: 3249 / 486

Advancing to step 6:
If we divide 3249 by 486, we get 6 and a remainder of 333.
The number 6 becomes the next digit in our result. 
Result so far: 1316.0
If we take 2916 away from 3249, we end up with 333.
Take the next digit (7) from the dividend and append it to 333, then repeat: 3337 / 486

Advancing to step 7:
3337 divided by 486 is 6 with a remainder of 421.
Use 6 as the next digit of our solution. 
Result so far: 13166.0
If we take 2916 away from 3337, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 8:
4210 divided by 486 is 8 with a remainder of 322.
The number 8 becomes the next digit in our result. 
Result so far: 13166.8
Subtract 3888 from 4210 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 9:
3220 divided by 486 is 6 with a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 13166.86
The remainder is 304 after subtracting 2916 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 10:
486 can be fit into 3040 6 times, resulting in a remainder of 124.
The next digit of our result is 6. 
Result so far: 13166.866
Subtract 2916 from 3040 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 13166.866 with a remainder of 0.0124.
