28991346 ÷ 486 
Our goal is to divide 28991346 by 486.

On to step 1:
2 divided by 486 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 486

Advancing to step 2:
28 divided by 486 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 486

Step 3:
486 goes into 289 0 times with a remainder of 289.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 289 leaves us with 289.
Grab the next digit (9) from the dividend, add it to 289, then carry on: 2899 / 486

Let's proceed to step 4:
486 goes into 2899 5 times with a remainder of 469.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 2430 from 2899 to get 469.
Fetch the next digit (1) from the dividend, attach it to 469 and continue: 4691 / 486

Moving on to step 5:
4691 divided by 486 is 9 with a remainder of 317.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 4374 from 4691, we get 317.
Grab the next digit (3) from the dividend, add it to 317, then carry on: 3173 / 486

Moving on to step 6:
486 can be fit into 3173 6 times, resulting in a remainder of 257.
Use 6 as the next digit of our solution. 
Result so far: 596.0
Deduct 2916 from 3173 and we're left with 257.
Fetch the next digit (4) from the dividend, attach it to 257 and continue: 2574 / 486

Step 7:
486 goes into 2574 5 times with a remainder of 144.
Put 5 as the next digit of the answer. 
Result so far: 5965.0
If we take 2430 away from 2574, we end up with 144.
Take the next digit (6) from the dividend and append it to 144, then repeat: 1446 / 486

Advancing to step 8:
486 goes into 1446 2 times with a remainder of 474.
Use 2 as the next digit of our solution. 
Result so far: 59652.0
If we subtract 972 from 1446, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 9:
486 goes into 4740 9 times with a remainder of 366.
Put 9 as the next digit of the answer. 
Result so far: 59652.9
If we subtract 4374 from 4740, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 10:
486 can be fit into 3660 7 times, resulting in a remainder of 258.
Write down 7 as next digit of the result. 
Result so far: 59652.97
The remainder is 258 after subtracting 3402 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 11:
2580 divided by 486 is 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 59652.975
If we take 2430 away from 2580, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
If we divide 1500 by 486, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 59652.9753
If we take 1458 away from 1500, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
The number 486 fits into 420 0 times, leaving a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 59652.9753
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 14:
4200 divided by 486 is 8 with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 59652.975308
If we subtract 3888 from 4200, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 15:
The number 486 fits into 3120 6 times, leaving a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 59652.9753086
Subtract 2916 from 3120 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 16:
486 goes into 2040 4 times with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 59652.97530864
Subtracting 1944 from 2040 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

In conclusion, the division gives 59652.97530864 with a balance of 9.6e-08.
