We look at the division of 42679288 by 259 
We want to divide 42679288 by 259.

Step 1:
When dividing 4 by 259, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 259

Moving on to step 2:
259 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 259

Let's proceed to step 3:
259 goes into 426 1 times with a remainder of 167.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 259 from 426 leaves us with 167.
Append the next digit (7) from the dividend to 167 and continue with: 1677 / 259

Let's proceed to step 4:
The number 259 fits into 1677 6 times, leaving a remainder of 123.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 123 after subtracting 1554 from 1677.
Bring next digit (9) of the dividend behind the 123 and repeat the process: 1239 / 259

Going ahead to step 5:
When dividing 1239 by 259, we get 4 with a remainder of 203.
Put 4 as the next digit of the answer. 
Result so far: 164.0
Subtracting 1036 from 1239 leaves us with 203.
Include the next digit (2) from the dividend after 203, then repeat: 2032 / 259

On to step 6:
259 goes into 2032 7 times with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 1647.0
Subtracting 1813 from 2032 leaves us with 219.
Grab the next digit (8) from the dividend, add it to 219, then carry on: 2198 / 259

Moving on to step 7:
When dividing 2198 by 259, we get 8 with a remainder of 126.
The next digit of our result is 8. 
Result so far: 16478.0
Subtract 2072 from 2198 to get 126.
Append the next digit (8) from the dividend to 126 and continue with: 1268 / 259

On to step 8:
When dividing 1268 by 259, we get 4 with a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 164784.0
If we subtract 1036 from 1268, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 9:
If we divide 2320 by 259, we get 8 and a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 164784.8
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.

Moving on to step 10:
259 goes into 2480 9 times with a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 164784.89
The remainder is 149 after subtracting 2331 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 11:
The number 259 fits into 1490 5 times, leaving a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 164784.895
Subtract 1295 from 1490 to get 195.
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 12:
259 goes into 1950 7 times with a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 164784.8957
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 13:
1370 divided by 259 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 164784.89575
If we take 1295 away from 1370, we end up 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.

Advancing to step 14:
750 divided by 259 is 2 with a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 164784.895752
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.

Step 15:
The number 259 fits into 2320 8 times, leaving a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 164784.8957528
If we take 2072 away from 2320, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 16:
2480 divided by 259 is 9 with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 164784.89575289
Subtracting 2331 from 2480 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

After the division, we end up with 164784.89575289 and a remainder of 1.49e-07.
