Let's divide 421502 by 68
Our goal is to divide 421502 by 68.

On to step 1:
If we divide 4 by 68, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 68

Moving on to step 2:
42 divided by 68 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 68

Moving on to step 3:
421 divided by 68 is 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 408 from 421 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 68

Let's proceed to step 4:
68 goes into 135 1 times with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we take 68 away from 135, we end up with 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 68

Moving on to step 5:
If we divide 670 by 68, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 619.0
The remainder is 58 after subtracting 612 from 670.
Append the next digit (2) from the dividend to 58 and continue with: 582 / 68

Moving on to step 6:
68 can be fit into 582 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 6198.0
Deduct 544 from 582 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
68 can be fit into 380 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 6198.5
Deduct 340 from 380 and we're left with 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 8:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 6198.55
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 6198.55 and a remainder of 0.06.
