We divide 10056680 by 421
Our goal is to divide 10056680 by 421.

Step 1:
When dividing 1 by 421, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 421

Step 2:
421 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 421

Let's proceed to step 3:
421 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 100, we get 100.
Grab the next digit (5) from the dividend, add it to 100, then carry on: 1005 / 421

Moving on to step 4:
421 goes into 1005 2 times with a remainder of 163.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 842 from 1005 to get 163.
Append the next digit (6) from the dividend to 163 and continue with: 1636 / 421

Advancing to step 5:
If we divide 1636 by 421, we get 3 and a remainder of 373.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 1263 away from 1636, we end up with 373.
Bring next digit (6) of the dividend behind the 373 and repeat the process: 3736 / 421

Moving on to step 6:
If we divide 3736 by 421, we get 8 and a remainder of 368.
Write down 8 as next digit of the result. 
Result so far: 238.0
The remainder is 368 after subtracting 3368 from 3736.
Include the next digit (8) from the dividend after 368, then repeat: 3688 / 421

On to step 7:
421 can be fit into 3688 8 times, resulting in a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 2388.0
The remainder is 320 after subtracting 3368 from 3688.
Include the next digit (0) from the dividend after 320, then repeat: 3200 / 421

Step 8:
421 goes into 3200 7 times with a remainder of 253.
The number 7 becomes the next digit in our result. 
Result so far: 23887.0
Subtract 2947 from 3200 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 9:
421 can be fit into 2530 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 23887.6
Subtracting 2526 from 2530 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 421, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 23887.6
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
421 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 23887.6
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 23887.6 with a remainder of 0.04.
