We're dividing 42291987 by 505 
We're looking to find how many times 505 goes into 42291987.

Step 1:
The number 505 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 505

Moving on to step 2:
505 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 505

Moving on to step 3:
The number 505 fits into 422 0 times, leaving a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 422 leaves us with 422.
Fetch the next digit (9) from the dividend, attach it to 422 and continue: 4229 / 505

Advancing to step 4:
The number 505 fits into 4229 8 times, leaving a remainder of 189.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 189 after subtracting 4040 from 4229.
Append the next digit (1) from the dividend to 189 and continue with: 1891 / 505

On to step 5:
505 can be fit into 1891 3 times, resulting in a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 1515 from 1891, we get 376.
Fetch the next digit (9) from the dividend, attach it to 376 and continue: 3769 / 505

Moving on to step 6:
The number 505 fits into 3769 7 times, leaving a remainder of 234.
Record the quotient 7 as the next digit in the result. 
Result so far: 837.0
If we subtract 3535 from 3769, we get 234.
Bring next digit (8) of the dividend behind the 234 and repeat the process: 2348 / 505

Let's proceed to step 7:
When dividing 2348 by 505, we get 4 with a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 8374.0
Subtract 2020 from 2348 to get 328.
Fetch the next digit (7) from the dividend, attach it to 328 and continue: 3287 / 505

Advancing to step 8:
The number 505 fits into 3287 6 times, leaving a remainder of 257.
Use 6 as the next digit of our solution. 
Result so far: 83746.0
Subtract 3030 from 3287 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 9:
The number 505 fits into 2570 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 83746.5
The remainder is 45 after subtracting 2525 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
The number 505 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 83746.5
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
If we divide 4500 by 505, we get 8 and a remainder of 460.
Put 8 as the next digit of the answer. 
Result so far: 83746.508
Subtract 4040 from 4500 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
If we divide 4600 by 505, we get 9 and a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 83746.5089
Deduct 4545 from 4600 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
When dividing 550 by 505, we get 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 83746.50891
The remainder is 45 after subtracting 505 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
505 goes into 450 0 times with a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 83746.50891
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 15:
When dividing 4500 by 505, we get 8 with a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 83746.5089108
If we subtract 4040 from 4500, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
505 goes into 4600 9 times with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 83746.50891089
The remainder is 55 after subtracting 4545 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 83746.50891089 and a remainder of 5.5e-08.
