We divide 642137 by 26
We want to figure out the number of times 642137 can be divided by 26.

Step 1:
6 divided by 26 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 26

Let's proceed to step 2:
If we divide 64 by 26, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 52 from 64 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 26

Moving on to step 3:
26 can be fit into 122 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 18 after subtracting 104 from 122.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 26

On to step 4:
26 goes into 181 6 times with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Deduct 156 from 181 and we're left with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 26

Step 5:
The number 26 fits into 253 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 2469.0
Deduct 234 from 253 and we're left with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 26

Let's proceed to step 6:
The number 26 fits into 197 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 24697.0
Subtracting 182 from 197 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 26 fits into 150 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 24697.5
Subtract 130 from 150 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 26 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 24697.57
Subtracting 182 from 200 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 24697.576
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 24697.5769
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
26 goes into 60 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 24697.57692
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
The number 26 fits into 80 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 24697.576923
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 26, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 24697.576923
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
200 divided by 26 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 24697.57692307
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 24697.57692307, with a leftover of 1.8e-08.
