We divide 12701673 by 421
We want to divide 12701673 by 421.

Advancing to step 1:
The number 421 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 421

Advancing to step 2:
421 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 421

Going ahead to step 3:
When dividing 127 by 421, we get 0 with a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Bring next digit (0) of the dividend behind the 127 and repeat the process: 1270 / 421

Step 4:
1270 divided by 421 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 7 after subtracting 1263 from 1270.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 421

Advancing to step 5:
421 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 421

Moving on to step 6:
If we divide 716 by 421, we get 1 and a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 301.0
Subtracting 421 from 716 leaves us with 295.
Grab the next digit (7) from the dividend, add it to 295, then carry on: 2957 / 421

Moving on to step 7:
The number 421 fits into 2957 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3017.0
If we subtract 2947 from 2957, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 421

Step 8:
The number 421 fits into 103 0 times, leaving a remainder of 103.
The next digit of our result is 0. 
Result so far: 30170.0
If we subtract 0 from 103, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
421 can be fit into 1030 2 times, resulting in a remainder of 188.
The next digit of our result is 2. 
Result so far: 30170.2
If we subtract 842 from 1030, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 10:
1880 divided by 421 is 4 with a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 30170.24
Subtracting 1684 from 1880 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
421 can be fit into 1960 4 times, resulting in a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 30170.244
Subtract 1684 from 1960 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final result is 30170.244 with a remainder of 0.0276.
