We look at the division of 42883258 by 661 
Our goal is to divide 42883258 by 661.

Going ahead to step 1:
If we divide 4 by 661, we get 0 and a remainder of 4.
Write down 0 as next digit of the 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 / 661

On to step 2:
When dividing 42 by 661, we get 0 with 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.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 661

Advancing to step 3:
428 divided by 661 is 0 with a remainder of 428.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 428, we get 428.
Include the next digit (8) from the dividend after 428, then repeat: 4288 / 661

Step 4:
If we divide 4288 by 661, we get 6 and a remainder of 322.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3966 from 4288 and we're left with 322.
Grab the next digit (3) from the dividend, add it to 322, then carry on: 3223 / 661

Step 5:
The number 661 fits into 3223 4 times, leaving a remainder of 579.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 2644 from 3223, we get 579.
Include the next digit (2) from the dividend after 579, then repeat: 5792 / 661

Let's proceed to step 6:
661 goes into 5792 8 times with a remainder of 504.
The next digit of our result is 8. 
Result so far: 648.0
Deduct 5288 from 5792 and we're left with 504.
Fetch the next digit (5) from the dividend, attach it to 504 and continue: 5045 / 661

Moving on to step 7:
If we divide 5045 by 661, we get 7 and a remainder of 418.
Put 7 as the next digit of the answer. 
Result so far: 6487.0
The remainder is 418 after subtracting 4627 from 5045.
Bring next digit (8) of the dividend behind the 418 and repeat the process: 4188 / 661

Let's proceed to step 8:
When dividing 4188 by 661, we get 6 with a remainder of 222.
Write down 6 as next digit of the result. 
Result so far: 64876.0
Subtract 3966 from 4188 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 9:
661 goes into 2220 3 times with a remainder of 237.
The next digit of our result is 3. 
Result so far: 64876.3
Subtracting 1983 from 2220 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 10:
661 goes into 2370 3 times with a remainder of 387.
Use 3 as the next digit of our solution. 
Result so far: 64876.33
If we take 1983 away from 2370, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

In conclusion, the division gives 64876.33 with a balance of 0.387.
