We look at the division of 42588997 by 836 
We want to divide 42588997 by 836.

Step 1:
If we divide 4 by 836, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
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 / 836

Step 2:
When dividing 42 by 836, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 836

Moving on to step 3:
425 divided by 836 is 0 with a remainder of 425.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 425, we end up with 425.
Grab the next digit (8) from the dividend, add it to 425, then carry on: 4258 / 836

Let's proceed to step 4:
When dividing 4258 by 836, we get 5 with a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 78 after subtracting 4180 from 4258.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 836

Let's proceed to step 5:
836 goes into 788 0 times with a remainder of 788.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Deduct 0 from 788 and we're left with 788.
Include the next digit (9) from the dividend after 788, then repeat: 7889 / 836

Moving on to step 6:
836 goes into 7889 9 times with a remainder of 365.
The number 9 becomes the next digit in our result. 
Result so far: 509.0
If we subtract 7524 from 7889, we get 365.
Take the next digit (9) from the dividend and append it to 365, then repeat: 3659 / 836

Going ahead to step 7:
If we divide 3659 by 836, we get 4 and a remainder of 315.
The next digit of our result is 4. 
Result so far: 5094.0
If we take 3344 away from 3659, we end up with 315.
Grab the next digit (7) from the dividend, add it to 315, then carry on: 3157 / 836

Moving on to step 8:
836 goes into 3157 3 times with a remainder of 649.
Record the quotient 3 as the next digit in the result. 
Result so far: 50943.0
If we take 2508 away from 3157, we end up with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Let's proceed to step 9:
836 goes into 6490 7 times with a remainder of 638.
The next digit of our result is 7. 
Result so far: 50943.7
If we take 5852 away from 6490, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 10:
If we divide 6380 by 836, we get 7 and a remainder of 528.
Put 7 as the next digit of the answer. 
Result so far: 50943.77
Subtracting 5852 from 6380 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final result is 50943.77 with a remainder of 0.528.
