We're dividing 510142 by 26 
We're looking to find how many times 26 goes into 510142.

Advancing to step 1:
26 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 26

Advancing to step 2:
26 can be fit into 51 1 times, resulting in a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 26 from 51 to get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 26

Advancing to step 3:
26 goes into 250 9 times with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 16 after subtracting 234 from 250.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 26

On to step 4:
26 goes into 161 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 196.0
Subtract 156 from 161 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 26

Let's proceed to step 5:
The number 26 fits into 54 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1962.0
If we take 52 away from 54, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 26

On to step 6:
If we divide 22 by 26, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 19620.0
The remainder is 22 after subtracting 0 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
220 divided by 26 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 19620.8
If we subtract 208 from 220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
26 goes into 120 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 19620.84
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
26 goes into 160 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 19620.846
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 19620.8461
If we subtract 26 from 40, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
When dividing 140 by 26, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19620.84615
Deduct 130 from 140 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
26 goes into 100 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 19620.846153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
26 goes into 220 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 19620.8461538
Subtracting 208 from 220 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
When dividing 120 by 26, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 19620.84615384
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 19620.84615384, with a leftover of 1.6e-08.
