We look at the division of 68420 by 45 
Our goal is to divide 68420 by 45.

On to step 1:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 45

Advancing to step 2:
68 divided by 45 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 68, we end up with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 45

Moving on to step 3:
The number 45 fits into 234 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 225 from 234 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 45

Moving on to step 4:
45 can be fit into 92 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtracting 90 from 92 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 45

Let's proceed to step 5:
45 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1520.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 6:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1520.4
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1520.44
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 1520.44 with a balance of 0.02.
