28606361 ÷ 321 
We want to figure out the number of times 28606361 can be divided by 321.

On to step 1:
The number 321 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 321

Going ahead to step 2:
If we divide 28 by 321, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 321

Moving on to step 3:
The number 321 fits into 286 0 times, leaving a remainder of 286.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 286, we get 286.
Bring next digit (0) of the dividend behind the 286 and repeat the process: 2860 / 321

Step 4:
If we divide 2860 by 321, we get 8 and a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 2568 from 2860 and we're left with 292.
Grab the next digit (6) from the dividend, add it to 292, then carry on: 2926 / 321

On to step 5:
If we divide 2926 by 321, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 2889 away from 2926, we end up with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 321

Advancing to step 6:
321 goes into 373 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 891.0
If we take 321 away from 373, we end up with 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 321

Let's proceed to step 7:
321 can be fit into 526 1 times, resulting in a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 8911.0
If we take 321 away from 526, we end up with 205.
Include the next digit (1) from the dividend after 205, then repeat: 2051 / 321

Let's proceed to step 8:
If we divide 2051 by 321, we get 6 and a remainder of 125.
The number 6 becomes the next digit in our result. 
Result so far: 89116.0
If we subtract 1926 from 2051, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
321 can be fit into 1250 3 times, resulting in a remainder of 287.
The number 3 becomes the next digit in our result. 
Result so far: 89116.3
Deduct 963 from 1250 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 10:
321 goes into 2870 8 times with a remainder of 302.
Write down 8 as next digit of the result. 
Result so far: 89116.38
If we subtract 2568 from 2870, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 11:
If we divide 3020 by 321, we get 9 and a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 89116.389
The remainder is 131 after subtracting 2889 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 12:
If we divide 1310 by 321, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 89116.3894
If we take 1284 away from 1310, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
321 can be fit into 260 0 times, resulting in a remainder of 260.
The next digit of our result is 0. 
Result so far: 89116.3894
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 14:
321 goes into 2600 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 89116.389408
Deduct 2568 from 2600 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
320 divided by 321 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 89116.389408
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 16:
When dividing 3200 by 321, we get 9 with a remainder of 311.
Write down 9 as next digit of the result. 
Result so far: 89116.38940809
Subtracting 2889 from 3200 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final outcome is 89116.38940809, with a leftover of 3.11e-07.
