We divide 117980 by 421
Let's see how many times 421 fits into 117980.

Going ahead to step 1:
If we divide 1 by 421, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 421

On to step 2:
421 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 421

Going ahead to step 3:
When dividing 117 by 421, we get 0 with a remainder of 117.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 117 after subtracting 0 from 117.
Include the next digit (9) from the dividend after 117, then repeat: 1179 / 421

Let's proceed to step 4:
421 goes into 1179 2 times with a remainder of 337.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 842 from 1179 and we're left with 337.
Take the next digit (8) from the dividend and append it to 337, then repeat: 3378 / 421

Let's proceed to step 5:
421 goes into 3378 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 10 after subtracting 3368 from 3378.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 421

Advancing to step 6:
421 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 280.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 7:
421 goes into 1000 2 times with a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 280.2
Subtract 842 from 1000 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 8:
The number 421 fits into 1580 3 times, leaving a remainder of 317.
Put 3 as the next digit of the answer. 
Result so far: 280.23
If we take 1263 away from 1580, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 9:
The number 421 fits into 3170 7 times, leaving a remainder of 223.
Use 7 as the next digit of our solution. 
Result so far: 280.237
Deduct 2947 from 3170 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 10:
If we divide 2230 by 421, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 280.2375
Subtracting 2105 from 2230 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 11:
The number 421 fits into 1250 2 times, leaving a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 280.23752
If we subtract 842 from 1250, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 12:
4080 divided by 421 is 9 with a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 280.237529
Deduct 3789 from 4080 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 13:
421 can be fit into 2910 6 times, resulting in a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 280.2375296
If we subtract 2526 from 2910, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 14:
421 can be fit into 3840 9 times, resulting in a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 280.23752969
Subtracting 3789 from 3840 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 280.23752969, and the remainder is 5.1e-08.
