We're dividing 851866 by 26 
We're looking to find how many times 26 goes into 851866.

Moving on to step 1:
If we divide 8 by 26, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 26

Moving on to step 2:
85 divided by 26 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 78 away from 85, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 26

Moving on to step 3:
26 can be fit into 71 2 times, resulting in a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 52 away from 71, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 26

Advancing to step 4:
198 divided by 26 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
Deduct 182 from 198 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 26

Step 5:
The number 26 fits into 166 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 3276.0
If we subtract 156 from 166, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 26

Moving on to step 6:
26 goes into 106 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 32764.0
Subtracting 104 from 106 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 7:
When dividing 20 by 26, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 32764.0
If we subtract 0 from 20, we 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.

Moving on to step 8:
26 goes into 200 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 32764.07
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
When dividing 180 by 26, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 32764.076
Subtracting 156 from 180 leaves us 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.

Let's proceed to step 10:
If we divide 240 by 26, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 32764.0769
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 26 fits into 60 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 32764.07692
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 26, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 32764.076923
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:
26 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 32764.076923
If we take 0 away from 20, we end up 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.

Going ahead 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: 32764.07692307
Deduct 182 from 200 and we're left 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.

Our division results in 32764.07692307 with a remaining 1.8e-08.
