Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 421

Going ahead to step 2:
37 divided by 421 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 421

Going ahead to step 3:
374 divided by 421 is 0 with a remainder of 374.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 374 to get 374.
Include the next digit (0) from the dividend after 374, then repeat: 3740 / 421

On to step 4:
3740 divided by 421 is 8 with a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 3368 from 3740 to get 372.
Grab the next digit (5) from the dividend, add it to 372, then carry on: 3725 / 421

Advancing to step 5:
When dividing 3725 by 421, we get 8 with a remainder of 357.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtracting 3368 from 3725 leaves us with 357.
Include the next digit (2) from the dividend after 357, then repeat: 3572 / 421

Moving on to step 6:
The number 421 fits into 3572 8 times, leaving a remainder of 204.
Write down 8 as next digit of the result. 
Result so far: 888.0
Deduct 3368 from 3572 and we're left with 204.
Grab the next digit (2) from the dividend, add it to 204, then carry on: 2042 / 421

Going ahead to step 7:
421 goes into 2042 4 times with a remainder of 358.
Use 4 as the next digit of our solution. 
Result so far: 8884.0
If we subtract 1684 from 2042, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 8:
If we divide 3580 by 421, we get 8 and a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 8884.8
The remainder is 212 after subtracting 3368 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
The number 421 fits into 2120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 8884.85
Subtracting 2105 from 2120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
When dividing 150 by 421, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 8884.85
If we subtract 0 from 150, we get 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 11:
421 can be fit into 1500 3 times, resulting in a remainder of 237.
Use 3 as the next digit of our solution. 
Result so far: 8884.8503
The remainder is 237 after subtracting 1263 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Moving on to step 12:
If we divide 2370 by 421, we get 5 and a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 8884.85035
The remainder is 265 after subtracting 2105 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 13:
421 can be fit into 2650 6 times, resulting in a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 8884.850356
Deduct 2526 from 2650 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 14:
1240 divided by 421 is 2 with a remainder of 398.
Put 2 as the next digit of the answer. 
Result so far: 8884.8503562
Subtract 842 from 1240 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 15:
421 goes into 3980 9 times with a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 8884.85035629
Subtract 3789 from 3980 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The quotient of the division is 8884.85035629, and the remainder is 1.91e-07.
