Let's divide 42080126 by 259
We're looking to find how many times 259 goes into 42080126.

On to step 1:
259 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
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 / 259

Let's proceed to step 2:
259 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 259

On to step 3:
If we divide 420 by 259, we get 1 and a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 259 from 420 and we're left with 161.
Fetch the next digit (8) from the dividend, attach it to 161 and continue: 1618 / 259

Moving on to step 4:
When dividing 1618 by 259, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 1554 away from 1618, we end up with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 259

Advancing to step 5:
If we divide 640 by 259, we get 2 and a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 162.0
If we subtract 518 from 640, we get 122.
Append the next digit (1) from the dividend to 122 and continue with: 1221 / 259

Let's proceed to step 6:
The number 259 fits into 1221 4 times, leaving a remainder of 185.
The next digit of our result is 4. 
Result so far: 1624.0
If we take 1036 away from 1221, we end up with 185.
Append the next digit (2) from the dividend to 185 and continue with: 1852 / 259

Moving on to step 7:
If we divide 1852 by 259, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 16247.0
If we take 1813 away from 1852, we end up with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 259

Going ahead to step 8:
The number 259 fits into 396 1 times, leaving a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 162471.0
Subtracting 259 from 396 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
The number 259 fits into 1370 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 162471.5
The remainder is 75 after subtracting 1295 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
If we divide 750 by 259, we get 2 and a remainder of 232.
The next digit of our result is 2. 
Result so far: 162471.52
The remainder is 232 after subtracting 518 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 11:
259 goes into 2320 8 times with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 162471.528
Subtract 2072 from 2320 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 12:
If we divide 2480 by 259, we get 9 and a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 162471.5289
If we subtract 2331 from 2480, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 13:
When dividing 1490 by 259, we get 5 with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 162471.52895
The remainder is 195 after subtracting 1295 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 14:
The number 259 fits into 1950 7 times, leaving a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 162471.528957
Subtracting 1813 from 1950 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 15:
The number 259 fits into 1370 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 162471.5289575
Deduct 1295 from 1370 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
When dividing 750 by 259, we get 2 with a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 162471.52895752
Deduct 518 from 750 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final result is 162471.52895752 with a remainder of 2.32e-07.
