We look at the division of 42521555 by 328 
Our goal is to divide 42521555 by 328.

Let's proceed to step 1:
328 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 328

Advancing to step 2:
If we divide 42 by 328, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 328

Let's proceed to step 3:
328 can be fit into 425 1 times, resulting in a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 328 from 425 leaves us with 97.
Grab the next digit (2) from the dividend, add it to 97, then carry on: 972 / 328

On to step 4:
When dividing 972 by 328, we get 2 with a remainder of 316.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 656 from 972 and we're left with 316.
Append the next digit (1) from the dividend to 316 and continue with: 3161 / 328

On to step 5:
3161 divided by 328 is 9 with a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 2952 from 3161 to get 209.
Take the next digit (5) from the dividend and append it to 209, then repeat: 2095 / 328

Let's proceed to step 6:
If we divide 2095 by 328, we get 6 and a remainder of 127.
Put 6 as the next digit of the answer. 
Result so far: 1296.0
Subtract 1968 from 2095 to get 127.
Fetch the next digit (5) from the dividend, attach it to 127 and continue: 1275 / 328

Advancing to step 7:
1275 divided by 328 is 3 with a remainder of 291.
Use 3 as the next digit of our solution. 
Result so far: 12963.0
Deduct 984 from 1275 and we're left with 291.
Include the next digit (5) from the dividend after 291, then repeat: 2915 / 328

Step 8:
2915 divided by 328 is 8 with a remainder of 291.
The next digit of our result is 8. 
Result so far: 129638.0
If we take 2624 away from 2915, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 9:
When dividing 2910 by 328, we get 8 with a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 129638.8
If we take 2624 away from 2910, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 10:
When dividing 2860 by 328, we get 8 with a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 129638.88
Deduct 2624 from 2860 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

In conclusion, the division gives 129638.88 with a balance of 0.236.
