2389012 divided by 421 
Let's see how many times 421 fits into 2389012.

Let's proceed to step 1:
421 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 421

Going ahead to step 2:
The number 421 fits into 23 0 times, leaving a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 421

On to step 3:
If we divide 238 by 421, we get 0 and a remainder of 238.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 238 and we're left with 238.
Bring next digit (9) of the dividend behind the 238 and repeat the process: 2389 / 421

Advancing to step 4:
If we divide 2389 by 421, we get 5 and a remainder of 284.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 2105 from 2389 and we're left with 284.
Bring next digit (0) of the dividend behind the 284 and repeat the process: 2840 / 421

On to step 5:
The number 421 fits into 2840 6 times, leaving a remainder of 314.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 2526 from 2840, we get 314.
Grab the next digit (1) from the dividend, add it to 314, then carry on: 3141 / 421

On to step 6:
If we divide 3141 by 421, we get 7 and a remainder of 194.
The number 7 becomes the next digit in our result. 
Result so far: 567.0
If we take 2947 away from 3141, we end up with 194.
Fetch the next digit (2) from the dividend, attach it to 194 and continue: 1942 / 421

Going ahead to step 7:
The number 421 fits into 1942 4 times, leaving a remainder of 258.
Record the quotient 4 as the next digit in the result. 
Result so far: 5674.0
If we subtract 1684 from 1942, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 8:
The number 421 fits into 2580 6 times, leaving a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 5674.6
Subtracting 2526 from 2580 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
540 divided by 421 is 1 with a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 5674.61
The remainder is 119 after subtracting 421 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 10:
421 can be fit into 1190 2 times, resulting in a remainder of 348.
The next digit of our result is 2. 
Result so far: 5674.612
If we subtract 842 from 1190, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 11:
3480 divided by 421 is 8 with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 5674.6128
Subtract 3368 from 3480 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
1120 divided by 421 is 2 with a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 5674.61282
Subtracting 842 from 1120 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 13:
If we divide 2780 by 421, we get 6 and a remainder of 254.
Put 6 as the next digit of the answer. 
Result so far: 5674.612826
Subtracting 2526 from 2780 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 14:
The number 421 fits into 2540 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 5674.6128266
If we subtract 2526 from 2540, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 5674.6128266 with a remainder of 1.4e-07.
