We look at the division of 68805653 by 421 
Let's see how many times 421 fits into 68805653.

Step 1:
If we divide 6 by 421, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 421

Moving on to step 2:
68 divided by 421 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (8) from the dividend to 68 and continue with: 688 / 421

Step 3:
When dividing 688 by 421, we get 1 with a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 421 from 688 to get 267.
Bring next digit (0) of the dividend behind the 267 and repeat the process: 2670 / 421

Let's proceed to step 4:
If we divide 2670 by 421, we get 6 and a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2526 from 2670 leaves us with 144.
Include the next digit (5) from the dividend after 144, then repeat: 1445 / 421

Advancing to step 5:
1445 divided by 421 is 3 with a remainder of 182.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
The remainder is 182 after subtracting 1263 from 1445.
Fetch the next digit (6) from the dividend, attach it to 182 and continue: 1826 / 421

On to step 6:
421 goes into 1826 4 times with a remainder of 142.
Put 4 as the next digit of the answer. 
Result so far: 1634.0
If we take 1684 away from 1826, we end up with 142.
Bring next digit (5) of the dividend behind the 142 and repeat the process: 1425 / 421

Let's proceed to step 7:
If we divide 1425 by 421, we get 3 and a remainder of 162.
Use 3 as the next digit of our solution. 
Result so far: 16343.0
The remainder is 162 after subtracting 1263 from 1425.
Fetch the next digit (3) from the dividend, attach it to 162 and continue: 1623 / 421

On to step 8:
421 can be fit into 1623 3 times, resulting in a remainder of 360.
Write down 3 as next digit of the result. 
Result so far: 163433.0
The remainder is 360 after subtracting 1263 from 1623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 9:
If we divide 3600 by 421, we get 8 and a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 163433.8
Subtracting 3368 from 3600 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 10:
When dividing 2320 by 421, we get 5 with a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 163433.85
Deduct 2105 from 2320 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 11:
421 goes into 2150 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 163433.855
The remainder is 45 after subtracting 2105 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 163433.855 with a remainder of 0.0045.
