Let's divide 28906682 by 421
Our goal is to divide 28906682 by 421.

On to step 1:
If we divide 2 by 421, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 421

Going ahead to step 2:
421 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 421

Moving on to step 3:
421 goes into 289 0 times with a remainder of 289.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 289 and we're left with 289.
Fetch the next digit (0) from the dividend, attach it to 289 and continue: 2890 / 421

Advancing to step 4:
421 goes into 2890 6 times with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 364 after subtracting 2526 from 2890.
Take the next digit (6) from the dividend and append it to 364, then repeat: 3646 / 421

Step 5:
421 can be fit into 3646 8 times, resulting in a remainder of 278.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 3368 from 3646 and we're left with 278.
Append the next digit (6) from the dividend to 278 and continue with: 2786 / 421

Advancing to step 6:
When dividing 2786 by 421, we get 6 with a remainder of 260.
The next digit of our result is 6. 
Result so far: 686.0
Subtracting 2526 from 2786 leaves us with 260.
Bring next digit (8) of the dividend behind the 260 and repeat the process: 2608 / 421

On to step 7:
If we divide 2608 by 421, we get 6 and a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 6866.0
If we subtract 2526 from 2608, we get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 421

Let's proceed to step 8:
If we divide 822 by 421, we get 1 and a remainder of 401.
Record the quotient 1 as the next digit in the result. 
Result so far: 68661.0
The remainder is 401 after subtracting 421 from 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 9:
421 goes into 4010 9 times with a remainder of 221.
Write down 9 as next digit of the result. 
Result so far: 68661.9
Subtracting 3789 from 4010 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 10:
421 goes into 2210 5 times with a remainder of 105.
The next digit of our result is 5. 
Result so far: 68661.95
If we subtract 2105 from 2210, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 11:
The number 421 fits into 1050 2 times, leaving a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 68661.952
If we subtract 842 from 1050, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
When dividing 2080 by 421, we get 4 with a remainder of 396.
Use 4 as the next digit of our solution. 
Result so far: 68661.9524
Deduct 1684 from 2080 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 13:
421 can be fit into 3960 9 times, resulting in a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 68661.95249
If we take 3789 away from 3960, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 14:
421 goes into 1710 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 68661.952494
If we take 1684 away from 1710, 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 15:
If we divide 260 by 421, we get 0 and a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 68661.952494
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
421 can be fit into 2600 6 times, resulting in a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 68661.95249406
Subtracting 2526 from 2600 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 68661.95249406 and a remainder of 7.4e-08.
